[Can Hawthorn Bananas Eat Together __ Hawthorn Bananas Simultaneously]

[Can Hawthorn Bananas Eat Together __ Hawthorn Bananas Simultaneously]

Hawthorn has a sweet and sour taste, but it has a bitter taste when it is not fully mature.

The most commonly made candied fruit and hawthorn flakes have the effect of appetizing and spleen; and banana is a fruit that replaces starch.

Eating more bananas can speed up the gastrointestinal motility, moisturize the bowel, and have a cold nature, and those who are hot can eat the fire and dry it.

Some people like to mix these two fruits, so is there any negative effect?

Hawthorn’s efficacy and role Hawthorn contains sugars, proteins, trace amounts, vitamin C, carotene, starch, malic acid, citric acid, calcium and iron, which are very beneficial to human health.

The main effects of hawthorn are: 1, treatment of cardiovascular diseases.

The main component of hawthorn is flavonoids, which have obvious pharmacological effects on the human cardiovascular system, and can reduce blood lipids, blood pressure, heart rate, and anti-arrhythmia.

2, spleen and digestion.

Hawthorn is a good medicine for strengthening the spleen and appetizing, digesting stagnation, promoting blood circulation and reducing phlegm.

3. Anti-cancer.

The flavonoid compound vitexin in hawthorn is a natural medicine with anti-cancer and anti-tumor effects, and it has a certain inhibitory effect on tumor growth, growth, infiltration and metastasis itself.

Hawthorn can be processed into hawthorn flakes, hawthorn cakes, hawthorn rolls, hawthorn cakes, candied hawthorn fruits, hawthorn tea, cantaloupe and so on. These foods are sweet and sour, and are very popular.

Can hawthorn be eaten with bananas?

However, oranges, hawthorns and bananas should not be eaten on an empty stomach.

For example, persimmon contains substances such as persimmon and pectin, which have a complementary astringent effect. They can be eaten in large amounts on an empty stomach, and are easily combined with gastric acid to form hard-to-dissolve lumps, which may cause “gastric persimmon stone disease”.At the same time, patients with cholesterol, gallstones and kidney stones should also be careful when eating persimmons, so as not to cause deterioration of the disease; bananas are rich in magnesium elements. If you eat a lot of bananas on an empty stomach, the magnesium content in the blood will suddenly increase, causing magnesium in the bloodImbalanced with calcium, irritates the gastric mucosa and is unhealthy.

[How about drinking ginseng every day]_ginseng_once a day_impact

[How about drinking ginseng every day]_ginseng_once a day_impact

Ginseng is a very precious medicine in life. It has pharmacological and health care functions. It is an important medicinal material used by the elderly to maintain the body and improve resistance.

Although ginseng has powerful effects and obvious effects, any food must have a degree of consumption, otherwise it will be counterproductive. Let’s take a look at what happens to drinking ginseng every day?

1. Although ginseng has good pharmacological effects, it should not be used for a long time.

The ancients had long noticed this.

Ginseng is mainly used for tonic deficiency. If the external evil does not go and is eager to use ginseng to make up for it, ginseng is not used to remove evil attacks and often leads to the occlusion of evil gas.

This will not only reduce the effect of nourishing the vital energy, but will make it difficult to cure the disease caused. Therefore, the condition should be analyzed before taking the medicine.

Traditional Chinese medicine believes that ginseng should be avoided for lung stagnation, chest tightness, suffocation, unexplained evils, and all evidence and fever.

Otherwise, things will go wrong, and things will go wrong.

2. Ginseng is often included in those with qi deficiency (such as palpitation, shortness of breath, spontaneous sweating, pale tongue, fat tongue, tooth marks, pulse knot generation and other symptoms).

For those with yin deficiency and fire (if there is no phlegm in the liver, upset tongue, dry tongue, afternoon hot flashes, night sweats, red tongue, pulse count and other symptoms), ginseng should not be used.

If used, constipation, epistaxis, etc. may occur.

Ginseng can nourish qi and strengthen the spleen and improve digestive function, but if it is used excessively for a long time, it can reduce appetite and stagnate for satiety.

If fullness is observed, ginseng should be terminated.

Taking fresh radish juice (or 3-6 grams of fried rice dumplings) can alleviate this symptom.

3, due to long-term use of ginseng can cause excitement, insomnia, neurasthenia, high blood pressure; some people also appear rash, edema and early morning diarrhea.

The institute classified the high blood pressure accompanied by nervous excitement, rash, and early morning diarrhea after taking ginseng as the “ginseng metabolic syndrome”.

The thief shouted to catch the thief!Selling equipment to steal intelligence

The thief shouted to catch the thief!Selling equipment to steal intelligence
Xinhua News Agency, Washington, February 12th (International Observation) Selling equipment to steal intelligence, the United States again exposed the Internet’s bad behavior.In the 1970s, the Swiss crypto equipment supplier Klipto AG was secretly corrected to obtain confidential information of other countries. The German side retreated shortly after the reunification of Germany and Germany, and the United States did not stop this intelligence stealing operation until 2018.  Analysts have pointed out that the United States has always been a self-proclaimed cybersecurity guard, and has frequently accused other countries of launching cyber attacks, but has ignored its own blemishes.The incident of stealing intelligence from other countries through Swiss company equipment once again highlighted the cyberbullying thinking of American thieves shouting and catching thieves.  The German media repeatedly suspected that the German-American replacement agency was acting on the equipment of Kripto AG in 1996, but Kripto AG refused to call it a basis.A long article published on the 11th by the United States “Washington Post” once again focused on this issue, revealing the relevant CIA confidential documents obtained by the newspaper and Deutsche TV joint investigation.  It is reported that around 1970, the CIA and West German intelligence agencies jointly acquired and actually controlled Kripto AG.The company has been selling encryption equipment to more than 120 countries, including Iran, India, Pakistan, and some Latin American countries, while virtue gains confidential information from other countries through back doors opened on the device.Foreign governments paid the United States and West Germany large sums of money, but let these two countries (possibly up to five or six countries) read their most confidential communications.  This set of information-stealing techniques has been repeatedly successful.It is reported that, through the equipment of Kripto AG, U.S. and West German intelligence personnel monitored the words and deeds of Iranian religious leaders during the 1979 hostage crisis at the U.S. Embassy in Iran and provided Argentine troops to Britain during the 1982 Maldivian WarFang’s intelligence, after the 1986 Berlin Ballroom bombing, grasped the relevant information of Libyan leaders.  It is reported that after the reunification of Germany and Germany in 1990, the German intelligence agency considered that the above-mentioned intelligence stealing operations were too risky, and then withdrew.The CIA immediately bought the German stake and continued the operation until 2018.  The above-mentioned actions disclosed by the bad media are just one example of the evil behavior of the US Internet, and there are many such examples.  According to Edward Snowden, a former US defense official employee, as early as 2009, the US National Security Agency had hacked into Chinese companies’ systems to steal source code, read customer lists and internal mail.  In April 2017, the media broke the news that a hacking organization related to the US National Security Agency attacked the transfer settlement system SWIFT, EastNets, the largest financial service provider in the Middle East, to steal host information, login credentials, etc.  Last June, U.S. intelligence agencies were exposed to attacks on some Iranian computer systems, paralyzing Iran ‘s rocket launch system; implanting malicious program code into the Russian power system to assassinate and detect intelligence or launch a cyber attack on the Russian power system.  In terms of system and strategy, in 2017, the U.S. government officially upgraded U.S. Army Cyber Command to the 10th U.S. Army Joint Operations Command, which is on par with major combat commands such as U.S. Central Command; in 2018, it released a network strategy report, focusing onPreemptive in cyberspace.Some analysts believe that various trends indicate that the United States is intensifying its preparations for cyber warfare.  Public opinion points out that the 淡水桑拿网 implementation of surveillance, theft of information, and undermining undermined the United States’ endeavours in the field of network security. However, it continues to accuse other countries of undermining network security.This double standard behavior highlights the hegemonic thinking of the United States.  Derriet was disturbed by the intelligence stealing operations described above, and there were voices in Germany and Switzerland in connection with the operation calling for investigation and expressing corrections.  In Germany, several federal lawmakers have asked the government to investigate the incident.Stefan Tomei, a member of the German Liberal Democratic Party, said such acts could not be tolerated.He said the federal government cannot remain silent and should immediately launch a full investigation without 上海夜网论坛 reservation.Left-wing MP Andre Hine called the intelligence stealing operation the biggest historical scandal at the German Federal Intelligence Agency.  In Switzerland, some media believe that this incident will probably affect the future neutrality of this permanent neutral country in international events.The “New Zurich” said that Switzerland has always been famous for maintaining neutrality in international affairs, and that Swiss technology companies also rely on the neutrality of the country to develop their businesses.Since the Snowden incident, U.S. suppliers have been labeled as unsafe, and Swiss companies have taken the lead in the international market.If, until two years ago, Kripto AG was actually part of the CIA’s surveillance network, this would affect the reputation of the entire Swiss industry and thereby undermine its competitive advantage.(Participating reporters: Yuan Zhang and Junxia Chen) Original title: International Watch: Selling Equipment to Steal Intelligence

  (3) Tracking of key global technology companies5. Merchants research: Perspectives on the frontiers of technologyConfirmation is very important research.

Therefore, we have launched a series of “Cloud Track Book” reports, which regularly update and improve the existing cloud industry database, and provide insight into the micro changes of IaaS, PaaS, and SaaS.

This article focuses on IaaS, focusing on the IaaS capital expenditures and transition changes and inflection points of upstream servers.

  1. The server is strongly related to IaaS capital expenditure, and Intel DCG corroborates the inflection point.

IaaS vendors are direct customers of server companies. In recent years, the rapid development of the cloud computing industry has also become an important factor in their growth.

From historical data, the growth rate of capital expansion of IaaS vendors and the growth rate of revenue of server companies show an increasing correlation. Therefore, the overall capital expansion of IaaS vendors is of great significance for tracking the marginal changes in upstream server demand.

At the same time, Intel’s data center business (DCG), as the upstream of the server industry, can be used as an important evidence to determine changes in server demand.

  2. The growth rate of IaaS capital expenditures at home and abroad in 19Q1-2 has bottomed out one after another and is expected to turn positive soon.

The overall growth rate of domestic IaaS vendors ‘capital expenditure continued to turn negative from 18Q2 until 19Q2 reached its inflection point. The decline in 19Q3 narrowed and the chain increased significantly.

Among them, Tencent’s capital expansion rate turned positive before 19Q3, and the rebound was obvious. We expect the industrial recovery to come.

The growth rate of the overall capital expenditure of overseas IaaS suppliers continued to turn negative from 18Q1 until the bottom point was reached in 19Q1, and the growth rate of each of the 19Q2-4 companies turned positive.

One quarter after the domestic IaaS industry cycle was earlier in foreign countries, the industry as a whole showed a clear state of collective recovery. The average IaaS vendor cloud revenue continued to grow at a high rate, and the inflection point for cloud upstream server demand was approaching.

In addition, Intel’s data center business (DCG) has rebounded sharply for two consecutive quarters from the bottom of 19Q2, directing the server industry to enter the boom upward channel, and IaaS supplier demand is urgent.

  3. The turning point of the domestic cloud office catalytic industry is accelerating. It is recommended to pay attention to Inspur Information.

The new crown pneumonia epidemic has caused a surge in demand for telecommuting, catalyzing the release of cloud demand in various industries, and major domestic IaaS vendors have urgently expanded their servers, which will accelerate the arrival of the domestic industry turning point.

In the long run, the domestic IaaS industry is still in an early stage compared to overseas, with a total of 12 in the world.

9%, there is still a lot of room for growth.

We are optimistic about the information of server leader Inspur. Zhongke Shuguang and others continue to benefit from the development of the cloud industry. At the same time, the rapid development of IaaS has also laid a good foundation for the development of application layers such as UFIDA and Jinshan Office.

  Risk Warning: The progress of the cloud computing industry is not up to expectations; the time span of the deterioration of the epidemic has exceeded expectations.

  (2) China Merchants Computer: The relaxation of refinancing rules is beneficial to computer innovative enterprises. On February 14, the CSRC issued relevant rules related to the adjustment of some terms of the refinancing system of listed companies.Optimize the non-public institutional arrangements, appropriately extend the three aspects of the validity period of the approval, and at the same time moderately relax the restrictions on the scale of non-public offering of stock financing, further expand the non-public offering share of listed companies, and help listed companies fight the epidemic and resume production.

  1. The refinancing of listed companies was moderately loosened, and regulatory policy guidance was further clarified.

The main contents of the new refinancing rules are: first, streamlining the issuance conditions and broadening the coverage of GEM refinancing; second, optimizing the non-public institutional arrangements to support listed companies dating strategic investors; third, appropriately extending the validity period of the approvals to facilitate the choice of listed companiesRelease window.The new regulations to be released generally focus on reducing the number of non-publicly issued shares of listed companies. From the specific content: 1) Restrictions on the issuance of GEM companies: Cancel the non-public issuance conditions for 2 consecutive years, and cancel public offerings.The condition that the return on assets at the end of the most recent period is higher than 45%; 2) The number of non-public offering objects, the scale of the issue, and the issue price have been further relaxed: the number of non-public offering objects has been adjusted to not more than 35, and the number of non-public offering shares has been changed fromExceeding 20% of the total share capital before the issuance is adjusted to 30%, and the issue price is not lower than the average price of the company’s stock 20% to 20% before the 20th trading day before the pricing benchmark date;Adjusted from 36 months and 12 months to 18 months and 6 months, once there is no restriction on the reduction of shares to be determined.

  2. Facilitate the refinancing of small and medium-sized startups based on technological innovation and improve the layout of related industries.

Due to the rapid development and change of the industry in which science and technology innovation enterprises are located, and human intelligence as the main progress, innovation business often requires a large amount of up-front expenditure before profitability, and the competition pattern has changed relative to the changes in traditional industries.

From the development history of European and American technology giants including Oracle, SAP, Symantec and other companies, we can grind and refinance is definitely an important means for science and technology companies to build competitiveness and become stronger.

It has been three years since the refinancing policy was tightened in February 2017. The scale of financing of small and medium-sized startups based on technological innovation has affected the development of the business to a certain extent.

With the introduction of new financing policy relaxation measures, and gradually incorporating capital market tools and continuous improvement, technology innovation companies are expected to benefit directly.

From the development history of overseas cloud computing and cyber security companies, refinancing is an important driving factor for the rapid expansion of their business. We believe that the introduction of new regulations on refinancing will gradually accelerate the development of internal cloud computing and cyber security listed companies. RelatedThe industrial layout will be further improved.

  Investment suggestion: Continue to focus on recommending the “cloud + security” combination: cloud service leader UFIDA, Kingsoft Office, Guanglianda, leading network security vendor Qixingxing, Green Alliance Technology, Nanyang Co., Ltd., convinced.

  Risk reminder: The policy support is lower than expected; the core technology development faces major challenges. (3) In the past six quarters when the price of silicon materials was at a low level, the basicchemicals department continued to be interrupted, and the Gunshan factory clearly provided for impairment.

OCI announced that the Gunsan plant’s production capacity will be shifted to the production of electronic-grade temporary products, while reducing the production of Korean solar-grade alternative materials.

Continue to reduce the withdrawal of Korean silicon materials represented by OCI, and reduce the global production capacity by nearly 10%.

At the same time, fierce competition has also led to the rapid withdrawal of domestic silicon materials second- and third-tier companies, and the market share will be concentrated on internal silicon materials leaders such as Tongwei, Daquan and Xinte, especially Tongwei, which will continue to increase production in the near future.

In addition, recently, due to the epidemic, some silicon materials have been transported, and the throughput of South Korea ‘s OCI silicon materials has begun to enter into maintenance (there may be a gradual withdrawal in the future). The overall supply of silicon materials is tight and prices are rising.

Overall, the pattern of the silicon material industry will gradually improve in the next six quarters.

  1. Sustained Korean silicon production capacity exit.

Due to the difference between the cost of South Korea’s OCI silicon materials and domestic leaders, and the continuous price of materials after “531” has dropped sharply, its basic chemicals department has continued to decline in the past few quarters, and the Gunsan plant has significantly depreciated.

The OCI announced that after the routine maintenance of the Gunsan plant is completed, the production capacity of some P1 production lines will be switched to the production of electronic-grade alternatives, while reducing the production of Korean solar-grade alternatives.

OCI, Hanwha’s high-temperature material production capacity accounts for about 10% of the world, and has long been an important supplier of domestic single-crystal silicon compacts.

If the South Korean ceiling is expected to continue to withdraw, it will bring an effective supply gap of nearly 10%.

  2. During the reshuffle of domestic silicon materials, the second and third lines quickly withdrew.

From 2018 to 2019, the price of silicon materials has fallen sharply. At present, domestic second- and third-tier silicon materials companies have generally changed, and the old production lines of mainstream silicon materials companies are no longer profitable.

In 2019, domestic manufacturers other than the five major manufacturers will replace about 7-8 substitutes. In 2020, this part may fall to the level of 2-3, and the market will further concentrate on large companies.

  Domestic competitive enterprises have prominent competitive advantages and resolutely expand production, and the market concentration has accelerated.

Domestic leading companies such as Tongwei, Daquan, and Xinte have obvious cost advantages. In the past two years, large-scale new capacity has been invested in construction, and the comprehensive cost advantage will be further expanded.

In 2019, Tongwei, special changes, Daquan, Zhongneng, and Dongfang hope that the total domestic share will be about 78%, and it may increase to nearly 90% in 2020, especially Tongwei shares, and yesterday announced the expansion plan:It is planned to double the capacity of silicon raw materials to 25 times within 4 years. If the expansion is realized, it will widen the gap with other companies.

  3. The price of silicon materials is expected to rise, and the scale will continue to improve in the medium term.

Initially, the short-term materials affected by the transformation of the diamond line have ended, and the growth rate of demand is close to the growth rate of downstream installed capacity. On the supply side, it is expected that the effective supply of silicon materials in the next six quarters will increase very little.

From a static perspective, the current long-term industry profit level has fallen to a low level, and the gross profit margin of Daquan has fallen to a historical average level. WACKER, OCI, REC, EBITA / income have fallen to negative numbers.

Due to the impact of the epidemic situation on the transportation of some silicon materials, South Korea’s OCI silicon material throughput has entered into maintenance (which may be gradually withdrawn in the future), the overall supply is tight, and the price of silicon materials has an upward trend.

  Investment advice: Recommend Tongwei shares, TBEA.

Attention: US stocks big new energy, Sanfu (chemical), Hesheng Silicon (chemical).

  (4) China Merchants Power New: Yiwei Lithium-Small battery business may reach a higher level. The power sector will usher in the general trend of the Internet of Everything. The battery demand for the Internet of Things is richer and stronger.The battery scale has leapt to the first place in the world, with the most comprehensive battery solutions and excellent rapid customization and response capabilities. The company’s lithium primary battery business may achieve a big leap in the great development of the Internet of Things.

The “Golden Bean” miniature lithium-ion battery cultivated by the company is suitable for wearable and other markets, and has been successfully extended to TWS applications. It is expected to break through in new and more applications in the future.

Overall, the company’s small battery business may reach a higher level.

At the same time, the company’s continuous strategic expansion of the power battery sector in the past 5 years is gradually entering the harvest period.

Maintain the highly recommended level and adjust the target price to 80-85 yuan.

  1. “Jindou” batteries have been successfully applied to the TWS field, and the company’s micro batteries are expected to gain more applications in the wearable field.

The company has independently developed the core equipment and products of this type of battery 5 years ago, and has formed a number of complete patent groups.

The company has cut into the supply chain of mainstream overseas TWS headset brands.

Due to the higher production barriers and patent issues of this product, it is expected to have an expected profit return, followed by a strong contribution after the ETC.Today Samsung released the new TWS headset Buds +, which increases the unit price of new products by 20.

$ 99 to $ 149.

At $ 99, the new product lasts 11 hours on a single charge, plus a charging case of 22 hours, an 83% and 69% increase over the previous generation. The new product’s earbud battery capacity is 83mAh, which is an increase of 46 over the previous generation.

6%, while the earbud battery weight has only increased by 5%, and battery performance has improved significantly.

TWS is a successful application of the company’s micro battery in the wearable field, and it is expected to gain more applications in new and diversified applications in the future.

  2. Lithium primary batteries will make great strides in the context of the great development of the Internet of Things.

Under the general trend of the Internet of Everything, the power demand in various types of IoT applications may blow up. In the long term, primary lithium batteries and small lithium-ion batteries will be the main power supply methods.

The scale of the company’s lithium primary battery has leapt to the number one in the world, forming a technology, process, and tooling platform. It has the most comprehensive battery solution and excellent rapid customization and response capabilities. The company’s lithium primary battery business may develop in the Internet of Things.To achieve a big leap.
  3. The company’s power business began to harvest.

Power battery has always been the company’s largest area in the past 5 years, and it has also had a serious impact and drag on statements.

In the past 5-6 years of development, the company has basically achieved accumulation and improvement from industrial to automotive grades. Soft-pack batteries have successively broken through international customers such as Daimler, Hyundai-Kia, etc., transforming production line optimization and climbing, it is expected that softThe battery pack will gradually start to make money.

At the same time, the company’s iron-lithium batteries not only compete and continue to profit, but also maintain capacity expansion.

It is expected that the power sector is expected to turn losses into profit in 2020 and begin to make positive contributions.

  Conclusions and recommendations: The company ‘s lithium primary batteries have global competitiveness, and the domestic consumption of lithium ion decomposition figure is the first echelon in the country. The company ‘s comprehensive power solution capabilities are stronger. Under the trend of “interconnecting everything, wireless, and lithium”, the companyThe small battery will maintain a strong growth, unless it is based on the assumption that the holding e-cigarette company does not grow, the company is estimated to be 28 times in 2020, and it continues to be highly recommended, with an adjusted target price of 80-85 yuan.

  Risk reminder: Changes in new tobacco policies, the company’s capacity expansion and customer development are lower than expected.

  (5) China Merchants Communication: short-term or long-term?

In-depth analysis of cloud video development opportunities This report believes that the foundation of cloud video development has been consolidated, the development of cloud video is a general trend, and the short-term epidemic is only accelerating the cultivation of user habits. Long-term cloud video addresses the pain points of high traditional video communication costs and narrow coverage.With the advent of great growth opportunities in the cloud video industry, we are optimistic about the long-term development opportunities of the cloud video industry and maintain a “recommended” investment rating.

  1. The foundation for the long-term development of cloud video has been consolidated. The epidemic has accelerated the cultivation of user habits and is expected to become the starting point for the accelerated development of cloud video.

With the maturity of the communication network infrastructure and the opening of the 5G era, the development of cloud computing technology and next-generation codec technology, and the popularity of intelligent hardware, the foundation of cloud video development has been consolidated, and the natural defects of hardware video conferencing cannot be adapted to the 5G era.We judge that the development of cloud video is the general trend, and the epidemic has only accelerated the cultivation of user habits. The window for accelerated development of cloud video conference has arrived earlier, and the benchmark SARS has driven the non-linear hardware video conference market into long-term prosperity.In the future, we believe that the epidemic is expected to help accelerate the development of the cloud video industry.

  2. There are differences in the competitive environment between China and the United States, and the scaling model is difficult to pass through in China. Cloud video companies can cut through vertical industries through the “cloud (software) + end (hardware)” approach, and finally penetrate into the large customer market.

Everyone in China and the United States has differences in user habits, estimation habits, and competition patterns, and users do not have the mobile video office habit. At the same time, the benefits of pure SaaS products are insufficient. Other Internet giants have participated in the cloud video conference market competition.However, in the vertical industry, there are a lot of budget needs and customized product requirements. It is difficult for the giants to cover all sub-sectors. At the same time, the vertical industry space is integrated. We believe that the opportunity of cloud video enterprise scale lies in the combination of cloud video and vertical industry applications.

  3. We believe that companies with high-quality product capabilities, a thorough understanding of subdivided industries, and accurate card positioning, and companies with high-quality sales channels are expected to stand out.

From the perspective of layout and technology, domestic cloud video companies have differed from each other beyond their competitive strength and development foundation.

Although most cloud video companies currently adopt a “cloud + end” layout, there are differences in technical path choices, business models, sales channels, etc. Different cloud video companies have different priorities and choose to subdivide the track instead. We believe that the productCapabilities, business models, sales channels, and vertical industry cards are the core competitiveness of cloud video companies.

  Investment suggestion: optimistic about the long-term development opportunities of cloud video.

Key recommendations: Huichang Communications, Yealink Networks, Starnet Ruijie; Suggested attention: 263, Qixin Group.

  Risk reminder: 5G construction is less than expected, cloud computing is developing less than expected, and competition in the industry is intensifying. (6) China Merchants Communications: 5G indoor proprietary licenses are officially issued.
3400MHz 5G indoor exclusive shared license to accelerate average 5G deployment and commercial progress.

In the 5G era, indoor application scenarios represented by ultra-high-definition video, AR / VR, intelligent manufacturing, and telemedicine are expected to account for more than 80% of traffic. Indoor network coverage must be prominent, and the scale is expected to increase significantly.

On February 10, the Ministry of Industry and Information Technology officially submitted radio frequency use licenses to three operators, namely China Telecom, China Unicom, and Radio and TV, and agreed to use the three companies nationwide.

3GHz?
3.

The 4GHz frequency band is used for 5G indoor signal coverage, and the 5G system deployment and commercial process are gradually promoted.

  1. In the 5G era, multiple solutions will continue to coexist. Digital room division systems are easy to deploy, easy to operate and maintain, efficient, large-capacity, and multi-mode and multi-frequency.

It is estimated that the market size of enterprise-level small base stations is close to 9 billion yuan.

3G / 4G-based indoor coverage technologies are mainly divided into two types: traditional DAS systems and small base station systems.

At present, indoor coverage is still dominated by passive distribution systems, but the passive components of the existing network of the DAS system are not compatible with 5G and the transmission line transmission loss is too large, it is difficult to achieve smoothness to 5G.

We judge that the 5G room will be mainly carried by active digital products. Small base stations are easy to deploy, easy to operate and maintain, efficient, large capacity, and the advantages of multi-mode and multi-frequency will be highlighted in the 5G period.

  2. From the perspective of the supply side, traditional small base station manufacturers and main equipment manufacturers have launched new digital room division systems. Both parties have their own advantages and are expected to occupy a place in the 5G small base station market.

At present, domestic small base station products and solutions include traditional small base station manufacturers, main equipment manufacturers, ODM manufacturers, and so on.
Traditional small base station manufacturers (such as Jingxin, 3D, etc.) have been cultivating in the small base station field for many years, and have the advantages of early technology accumulation, customer resources, and brands.

However, in the 4G era, main equipment vendors have also begun to make efforts to include multiple product portfolios to supplement and seize the small base station market.
ODM manufacturers (such as Foxconn, etc.) have not formed a threat due to the lack of core technical capabilities.

It is recommended to focus on the main equipment manufacturers,[Riskanda],[Jinxin Communication](Hong Kong Stocks),[3D Communication].

  Investment suggestion: 5G scale construction starts, cloud computing enters the substantive landing stage, 5G applications accelerate development, and the communication sector will be laid out around “one core + three main lines” in 2020.

  This week’s key recommendations: Halo New Network, Baoxin Software, StarNet Ruijie, Tianfu Communication, Zhongji Xuchuang, Taichenguang, Haige Communication, Yealink Network, Huichang Communication, China Unicom Suggested attention: Inspur Information, Ziguang Co., Ltd., Fiberhome Communications, Huagong Technology (covered by China Merchants Electronics Group), Xinyisheng, No. 100 Holdings, Dataport, Guangxun Technology, Sega Technology, Mobile Communications, Mobile Communications, Topview Information, 263,Qixin Group (covered by China Merchants Light Industry Group) Risk warning: Sino-US friction escalates, new pneumonia spreads more than expected, 5G investment scale is less than expected, and cloud computing investment growth slows down (7) China Merchants Communications: Zhongji Xuchuang-Proposed acquisition of Chengdu ReserveHan ‘s majority equity, complementing the telecommunications product line, creating a global optical module giant event: The company issued an announcement on February 14th, intending to acquire all or part (finally a large amount of 51%) of Chengdu Chuhan Technology Co., Ltd., the company and Chengdu ChuanHan 29 shareholders (total holding Chengdu Chuhan 56.

0044% shares) signed a framework agreement, and the purchase price is tentatively set at RMB 5.

7.2 billion, all paid in cash.

Before the official transaction documents of this acquisition are signed, if other shareholders of Chengdu Chuhan intend to sell their shares in Chengdu Chuhan to the company, the company will make an acquisition in accordance with relevant terms.

  Comments: 1. Chengdu Chuhan has significant advantages in large-scale manufacturing capabilities, which is expected to help Xuchuang become more and more competitive in the telecommunications market. Telecom’s two-wheel drive Xuchuang continues to grow rapidly.

  2. Capital spending of North American cloud giants continues to pick up, which is expected to drive the company’s performance back to a fast growth track. 3, the global high-speed optical module leader, 100G and 400G drive performance growth.

North American data centers are still developing at a high speed. The demand for 100G is still growing. The customer demand for high-speed optical modules such as 100G is still growing. At the same time, the demand for new 400G is also increasing. This translates into the continuous digestion of enterprise inventory.With the shift in recovery and the inheritance of 400G to 100G, datacom market demand is expected to continue to pick up.

The number of 100G products of the company remains in the previous rank, and the customer certification and introduction of 400G new products remain the leader. The company is one of the few 400G suppliers recognized by major customers in the world. The barriers of 400G product technology are high. The company has high-quality chip suppliers.Channels, leading research and development teams, strong research and development capabilities, and high-quality 400G products are strengthening their leading positions in the North American and domestic data center markets.

  4. 5G optical modules are expected to become a new driving force, bringing new growth points to performance.

In the 5G era, the average speed and number of base station optical modules of operators will increase, and the demand for driving optical modules will increase significantly. It is expected that the construction of 5G base stations will start in 2019. It is expected that the construction peak period (2020) will be 2020-2021.

The company began to deploy 5G base station optical module products in 2015. Currently, there are pre-transmission, mid-transmission, and back-transmission of a full range of 5G base station optical module products.

In terms of 5G front-transmission optical modules, the company has achieved a good share and orders, and has achieved batch delivery. It is expected that the company’s investment volume this year is expected to remain the industry leader.

We believe that the company is facing a breakthrough in the 5G era, and the return to growth of the telecommunications market is expected to become a new driving force for the company.

  5. The global leader in high-speed optical modules, benefiting from 5G and 400G two-wheel drive, maintaining the “strongly recommended-A” level.

The company maintains a leading position in the data center market in North America and China. It has high-quality chip supply channels and strong R & D capabilities, transforming the gradual recovery of the digital communication market and the increase in the supply of 400G products. The company’s profitability is expected to gradually increase;In the module market, the company has a comprehensive 5G base station optical module product layout for front, middle, and back. The company is expected to become the main provider of base station optical modules in the 5G era.

If the company’s merger with Chengdu Chuhan is successful, it is expected to significantly increase the company’s competitiveness in the telecommunications optical module market, and further strengthen the company’s competitiveness in global data centers, and it is expected to become a leading company in the data communications and telecommunications markets.

We estimate the company’s net profit for 2019-2021 will be 5 respectively.

1.8 billion, 9.

01 billion, 13.

5.6 billion yuan, corresponding to a PE of 86-20 in 2019-2021.

We have sorted out the automotive electronics industry chain, and we are mainly optimistic about the five sub-tracks.

  Investment Summary The automotive industry enters the deepwater area of technological evolution, A.

C.

E.

The trend of S (intelligent, networked, electrified, and shared) means that cars have become a carrier of multi-industry integration.

We believe that this round of the automotive industry revolution will be a process that is based on 西安耍耍网 electrification and cooperates with cross-border development of energy, communications, transportation and other fields to ultimately reshape the industrial ecology.

In this process, we believe that the three power systems should not be used as a substitute for traditional powertrains, but that all vehicle components are converted to electronic and digital directions, bringing basic data; the electrical architecture is accelerating to land,The access network produces a synergy effect of “vehicle-road-cloud-network”.

  We have sorted out the main segments of automotive electronics, combined with market size and monopoly level, and entered the cloud to sort. We are relatively optimistic about the Chinese parts suppliers’ five major tracks of smart cockpit, sensors, thermal management, lights and steering systems.development of.
  From the technical level, automotive parts have developed from traditional mechanical products to intelligent products controlled by electronic information systems. At present, electronic technologies are used in powertrains, vehicle controls, chassis systems, and communications.Application has caused exhaust emissions, safety, comfort and entertainment have been improved.

However, the requirements of smart cars go further. Advanced sensors and new technologies such as artificial intelligence are needed to make cars have the ability to drive autonomously and gradually become smart mobile spaces and application terminals.

In essence, intelligent cars put forward all-electronic requirements for all powertrain systems, body control systems, driver assistance and cockpit systems, safety and comfort systems, and intelligent driving systems.

  Chart: Overview of the automotive electronics industry chain under the current distributed electrical architecture Source: Marklines, strategic analysis, CICC Research (click image to view high-resolution image) The electrical architecture is accelerating towards the centralized direction through the electronics of a large number of automotive componentsWith the advent of ADAS, autonomous driving, active safety and other functions, the number of electronic control units (ECUs) in cars will increase significantly.

However, the existing electronic diversified electrical and electronic architectures have problems such as rising costs, redundant operations, slow replacement speeds, and multiple user experiences.

  In order to solve the above problems, the future automotive electronic and electrical architecture will gradually move to the domain architecture, and the direction of central computing architecture will become the consensus of the industry.

Under the domain architecture, the body is divided into different domains, and each domain controller is responsible for processing data in that domain.

Under the central computing architecture, the central computing platform processes the entire vehicle data to achieve optimal decision-making, and the cloud server is also responsible for the storage and calculation of some data.

  Chart: Trends in the changes in the automotive electrical and electronic architecture Source: Bosch, CICC’s research department driven by intelligent connected vehicles, the size of the Chinese / global automotive electronics market will reach USD 131.6 / USD 47.6 billion in 2025 According to Strategy Analytics, IHS Based on the data of automobiles and other institutions, we calculate the market size of various fields according to the following formula: total market size = system unit price * (automobile output * system penetration rate).

  Chart: China’s automotive electronics market will nearly double from 2020-2025, CAGR2020-2025 is about 13.

5% Source: IHS, Strategic Analysis, CICC Research Research Chart: Global automotive electronics growth is slower than China, CAGR2020-2025 is about 5.

5% Source: IHS, Strategy Analytics, CICC Research Department’s value transfer from sub-components to systems and software. We divide the investment opportunities of automotive electronic circuit into current stage and five years later (under domain architecture and central computing architecture).).

  At this stage, due to consumer demand for safer, more environmentally friendly, and smarter cars, the development of automotive electronics is still dominated by the electronicization of sub-components; we believe that under the domain controller and central computing architecture,Systems and software will occupy a greater proportion in the automotive electronics investment track.

  Automotive electronic track under distributed architecture: It is recommended to pay attention to automotive chips. Under the distributed architecture of cockpit electronics and safety systems, there are many automotive electronic tracks.

We have selected 10 investment areas in the entire industry chain, namely the lighting system, braking system, steering system, transmission system in powertrain control module, and safety system in safety comfort module in vehicle and vehicle control modules., Thermal management, seats, sensors in smart driving modules, chips, cockpit electronics.

Among them, we artificially eliminated the power system, because the battery part is undoubtedly the most valuable, but we attribute it to electrochemistry more than automotive electronics.

  We classify the above 10 investment areas according to market size, degree of monopoly, and biological scores of entry doors (where the degree of interaction is scored in reverse order, taking into account that during the transformation of the industry, it is easier for Chinese companies on the track to take shape to accelerate penetration)A map of investment opportunities in the industrial chain, including chips, cockpit electronics, and thermal management.

[A kind of bird’s nest is a good bird’s nest_A kind of bird’s nest is the best]

[A kind of bird’s nest is a good bird’s nest_A kind of bird’s nest is the best]

Bird’s nest is the most familiar food.

But people only know bird’s nest, and the type or grade of bird’s nest is unrecognizable.

So delicious high-quality bird’s nest should be uncommon, so people usually may not be too clear about the role of bird’s nest.

Bird’s nest has a great effect, it can regulate various parts of the human body.

Prevent disease.

So what kind of bird’s nest is good? What kind of bird’s nest is best?

What kind of bird’s nest is good?

The method of distinguishing the quality of bird’s nests is as follows: 1. A bird’s nest with good dryness must have a high dryness, and it will break if it is slightly folded.

The higher the dryness, the easier it is to store. It should be kept in a cool place and sealed to prevent mold.

Poor bird’s nests are not dry enough to meet the standards, and it is not easy to bend them by manual bending. Such bird’s nests have high humidity, occupy a large amount, and are not easy to place.

It should be pointed out that if the bird’s nest needs to be transported, it is necessary to spray water appropriately. If the bird’s nest is not sprayed, the foot-dried bird’s nest will be easily broken.Is a very conscientious business!

It does not mean that its bird’s nest quality is not good.

2. Whether the high-quality bird’s nest can see clear lines under the sun, and there may be a certain gap. This is because there are feathers in the bird’s nest, which need to be picked. However, the gap may be generated after artificial hair picking.This kind of bird’s nest is not treated by brushing and seaming.

Inferior bird’s nest, in order to increase weight and make the bird’s nest suddenly dense, will use glue to fill the gap after picking hair, and the lines are not clear in the sun. This kind of bird’s nest is very cost-effective. I don’t know how much glue is in the amount.Content, and there is no oxide on the body, it may be harmful.

3. The color of the natural bird’s nest is actually a bit gray or yellow. It will not use bleaching and other treatment methods, and it is artificially picked. It will inevitably have small residues of bird’s hair, which can be seen on the bird’s nest.To some little swallowhair.

For the bird’s nest of poor quality, in order to save labor costs, use some potions to remove hair without leaving any traces of bird’s hair.

Some are also bleached or dyed. After bleaching, the bird’s nest is very white, and the red-colored bird’s nest pretends to be a congested bird. The color is fake at first glance.

4. It is inevitable that the broken bird’s nest will fall down during the processing.

Pure natural bird’s nest, after processing, the bird’s sac will be lowered, so it will overlap and be thin, and will not stick the scraps back.

In order to save costs and increase weight, inferior bird’s nests will be covered with thick debris on the bottom of the bird’s nest. It looks very unnatural, and the debris is not known what it is, most likely notBird’s nest.

5, hair head bird’s nest hair head refers to the weight of the bird’s nest before and after foaming.

High-quality swallow hair heads are generally more than 6 times, and some can even reach 8?
9 times, it depends on the quality of the bird’s nest, the time of foaming and the technology.

And the inferior bird’s nest, because of the potion treatment or the brushing, caused a small amount of bird’s nest to be damaged, and it is not easy to foam, the hair of the foam is relatively small, and even the foam cannot be foamed at all.

6. After the bird’s nest with good taste is stewed, it will have an egg white fragrance and the taste will be softened. If it is a bird’s nest, its fragrance will be more intense, the taste will be smooth, and the Q will play.

Bird’s nests of poor quality are usually treated with potions or brushes. After they are stewed, they have no scent and taste bad. Some even feel the taste of gum, which makes people suddenly have no desire to eat.

Among them, vitamin A can promote growth and enhance resistance to disease, which is necessary to maintain normal reproductive power and vision; thiamine can resist beriberi, promote appetite, digestion, and protect the nervous system; riboflavin can promote normal growth anddevelopment.
Can people with diabetes eat bananas?
1. Both the sugar content and glycemic index of bananas are high. The food glycemic index is used to measure the effect of carbohydrates in food on blood glucose concentration.
According to the nutritionist’s measurement, when the glycemic index is below 55, the food is a hypoglycemic index food; when the glycemic index is 55-70, the food is a medium glycemic index food; when the glycemic index is 70When this is the case, the food is a hyperglycemic index food.
Foods with high glycemic index have fast digestion and high absorption rate after entering the gastrointestinal tract, fast release of glucose, high peak value of glucose after entering the blood, that is, high blood glucose; foods with low glycemic index have the opposite.
Among fruits, the glycemic index of bananas was higher year-on-year, at 52, apples at 36, and grapefruit at 25.
2. People with diabetes may eat bananas. Bananas are rich in vitamins and minerals, among which potassium and magnesium are particularly high (a medium-sized banana contains 451 mg of potassium).
Potassium prevents blood pressure from rising and muscle spasms, while magnesium has the effect of eliminating fatigue.
Banana also has a good role in promoting digestion and absorption.
Diabetics, especially those with diabetes and hypertension, can still eat bananas under the principle of a balanced diet and a moderately controlled diet.
It is best to eat bananas with good blood sugar control. The standard is: postprandial blood sugar <10mmol / L, glycated hemoglobin less than 7. 0%, blood sugar is stable, there is no big fluctuation in a short time. In addition, when hypoglycemia occurs, if there are only bananas around, do not worry too much, eat immediately to correct hypoglycemia, and immediately look for carbohydrates or glucose powder, and pay attention to testing blood sugar. Third, the benefits of bananas for diabetics: 1. Lowering cholesterol and high cholesterol can cause coronary heart disease. Those who have high serum cholesterol can use 50 grams of banana fruit stems, wash the slices, and drink with boiling water. Drinking for 10 to 20 days can reduce cholesterol. 2. Prevention and treatment of gastrointestinal ulcers Patients with gastrointestinal ulcers often take Baotaisong, which often causes gastric bleeding. And banana contains a chemical that can prevent gastric ulcers, which can stimulate the growth and reproduction of gastric mucosal cells, and produce more mucosa to protect the stomach. 3, treatment of hypertension and hypertension and cardiovascular and cerebrovascular disease patients often have more "sodium" and "potassium" less, and bananas are rich in potassium ions. Potassium ions can inhibit the contraction of blood vessels and damage the cardiovascular system by sodium ions. Eating bananas can maintain the sodium-potassium balance and acid-base balance in the body, keep the nerves and muscles normal, and coordinate the contraction of the heart muscle. Therefore, eating 3 to 5 bananas daily is beneficial to patients with hypertension and cardiovascular and cerebrovascular diseases. 4, treatment of depression Banana contains a substance that can help the human brain to produce serotonin, making people feel happy, lively and cheerful. Patients with depression can usually eat more bananas to reduce depression, disappoint pessimism, and dissatisfaction with worldly dissatisfaction. 5. Treatment of skin pruritus. Banana skin contains currantin, which can inhibit the growth of bacteria and fungi. Experiments have proven that banana peel is effective in treating itching and beriberi caused by fungi or bacteria. Patients can select fresh banana peels and rub it repeatedly on the itchy skin, or mash them into mud, or wash them with decoction for several days. 6, the treatment of cough lung fever cough with 1 or 2 bananas, stewed with rock sugar. 1-2 times a day for several days, the effect is good. 7. For the treatment of hemorrhoids and blood in the stool, eat 2 bananas on an empty stomach daily, or cook without peeling and eating.Can intestinal laxative and reduce hemorrhoid bleeding. 8. Weight loss Because of the high starch content in bananas, it is easy to fill up. In addition, it takes some time for starch to be converted into sugars in the body, so it does not produce too much energy accumulation. From this perspective, bananas can be used as the first choice for weight loss. Fourth, can black bananas still be eaten? The darkening of the banana skin is actually the manifestation of anthracnose of bananas. It is named after the symptoms similar to anthrax of humans. The pathogenic bacteria are banana spores. This kind of bacteria does not cause any effect on the human body. This symptom is only manifested when the banana is ripe. Black spots on the skin indicate that the banana is fully ripe. At this time, the taste and flavor are the best. At the same time, immature bananas are rich in amino acids, which easily lead to constipation, and the residual acid content is greatly reduced after ripening. Therefore, it is the best time to eat bananas when dark spots appear on the skin. However, it is not recommended to eat when the flesh is darkened and rotten.
