Pay attention to the suitability of choosing ppe

According to statistics, in 2010 China's e-commerce market share of about 480 billion yuan, 3 years will be 40% speed increase, some experts predict that the future China's fastest-growing may be e-commerce. Five years later, China will dare to overtake the United States to become the world's largest e-commerce market.

Love yarn International Chairman Zou Jifu that online sales have unparalleled advantages, low sales غير مجاز مي باشدts, involving a wide range of promotion easier, closer to the target consumer, and more targeted. Therefore, e-commerce is the underwear business to achieve rapid development of the new engine. Underwear business if you are not involved in e-commerce, the future is likely to be eliminated by the market. I believe that in 2012, the market share of e-commerce will continue to expand. The love yarn should also intensify its efforts to continue to broaden sales channels, keep up with the trend and continue to develop to meet the spring of e-commerce.

It is understood that Love yarn International Inc. is a collection of underwear research and development, design, production, management, marketing in one, to care for women's health responsibility as a large modern enterprise groups, love yarn underwear design team to take full account of the characteristics of the East's female body, the use of Medical, fat, ergonomics and professional underwear design principles, design and development of the fashion + comfortable + healthy underwear, not only well-groomed body, but also care of the breasts, so that female friends to experience the love yarn underwear to bring their health Comfortable, beautiful and confident. This year in August, Love yarn-Garfit underwear flagship store (http://getfit.tmall.com/) officially settled in China's largest electronic trading platform - Taobao, this strategic move to Love yarn international development plug-in take-off The wings, you can use "thousands of miles" to describe. Love yarn plans next year, Bai You Ti also involved in e-commerce, and now are stepping up preparatory work.

According to reports, Love yarn GetFit settled in Taobao, in just a few months total sales doubled, have welcomed the Teacher's Day, Mid-Autumn Festival, National Day, Double Ten Festival and so on one after another sales peak, which Love yarn for the first time involved in e-commerce is a great inspiration. Love yarn International Chairman Mr. Zou Jifu told reporters that now a group of online shopping has changed from "Amoy sweet" to "Amoy brand", Love yarn brand underwear design simple and stylish, excellent quality and price-friendly, so I got Amoy brand underwear consumption Of all ages. In addition, the Internet in China has gone through more than 10 years. Once young people have become the main body of consumption. Especially after 70s were replaced by 80s and 90s, after 80s and 90s, they have opened their minds and pursued freedom and individuality. The pursuit of fashionable things, no doubt, they have become the main force in the underwear consumption, underwear will be the sudden emergence of the Internet sales, underwear industry pattern will also be enlarged tens of times, hundreds of times.

Critics believe that if e-commerce was once as delicate as a bud, not mature enough, then the current e-commerce has become a bloom of flowers, the development will be more robust, stronger and more competitive .

Practice has proved that e-commerce broke the geographical restrictions, reduce غير مجاز مي باشدts, save staff and unnecessary expenses, but also conducive to the spread and promotion of the Internet, online shopping has become the mainstream trend, there will be more and more young people to join the online shopping team, help Push the "finger economy" development, lovers underwear online shopping share larger "cake" is also expected.

Led displays have great potential due to their energy saving, environmental protection, and long life. But the temperature is very important for the led display, the temperature of the led display: relates to the led display life, light efficiency, color and so on. So the right temperature is very important for the led display.

The effect of temperature on the led display has the following five points:

First, the temperature is too high will lead to the complete destruction of led display (1) led display operating temperature exceeds the chip's carrying temperature will make the led display's luminous efficiency is rapidly reduced, resulting in significant light failure, and cause damage;

(2) The LED display is mostly made of transparent epoxy resin. If the junction temperature exceeds the solid phase transition temperature (usually 125°C), the encapsulating material will change to a rubbery shape and the thermal expansion coefficient will suddenly rise, resulting in the open and failure of the LED display. .

Second, the temperature will shorten the life of the led display The life of the led display as its light decline, that is, a long time, the brightness is getting lower and lower until the last extinguished. Usually defines the LED display light flux decay time 30 for its life.

The reason that led to the led display light fades usually has the following aspects:

(1) The defects existing in the LED display screen chip material will quickly proliferate and multiply at a high temperature until invading the light emitting area, forming a large number of non-radiation recombination centers, and seriously reducing the luminous efficiency of the led display screen. In addition, under high temperature conditions, the micro-defects in the material and the fast-spreading impurities from the interface and the plate will also be introduced into the light-emitting region to form a large number of deep levels, which will also accelerate the light decay of the LED display device.

(2) The transparent epoxy resin will be denatured and yellowed at high temperatures, affecting its light transmission performance. The higher the operating temperature, the faster the process will proceed. This is another major reason for the decline of the LED display.

(3) The light decay of the phosphor is also a major factor affecting the light fade of the LED display, because the attenuation of the phosphor at high temperatures is very serious.

Therefore, the high temperature is the cause of led display failure, shortening the main source of led display life.

Different brands of LED display light decline is different, usually led display manufacturers will give a set of standard light decay curve. LED display luminous flux attenuation caused by high temperature is irreversible, led display screen does not occur before the irreversible light attenuation of light flux, called the led display "initial luminous flux."

Third, the increase in temperature will reduce the luminous efficiency of the led display The temperature affects the led display luminous efficiency reasons include the following aspects:

(1) As the temperature increases, the concentration of electrons and holes increases, the band gap decreases, and the electron mobility decreases.

(2) When the temperature rises, the probability of radiative recombination of electrons and holes in the potential well decreases, resulting in non-radiative recombination (heat generation), thereby reducing the internal quantum efficiency of the led display.

(3) Temperature rise causes the blue light wave peak of the chip to shift toward the long wave direction, which makes the emission wavelength of the chip and the excitation wavelength of the phosphor unmatched, and also causes the reduction of the external light extraction efficiency of the white light led display screen.

(4) As the temperature rises, the quantum efficiency of the phosphor decreases and the light emission decreases, and the external light extraction efficiency of the led display screen decreases.

(5) The performance of silica gel is greatly affected by the ambient temperature. As the temperature rises, the thermal stress inside the silica gel increases, resulting in a decrease in the refractive index of the silica gel, thereby affecting the light efficiency of the led display.

Fourth, the temperature on the led display light-emitting wavelength (light color) The led display light emission wavelength can generally be divided into the peak wavelength and the main wavelength. The peak wavelength is the wavelength with the largest light intensity, and the dominant wavelength can be determined by the X, Y color coordinates, reflecting the color perceived by human eyes. Obviously, the change in the light emitting wavelength of the led display caused by the junction temperature will directly cause the human eye to feel differently about the light color of the led display. For a led display device, the bandgap value of the light emitting region material directly determines the wavelength or color of the device's light emission. As the temperature rises, the bandgap of the material will decrease, resulting in longer device emission wavelengths and red-shifted colors.

Fifth, the temperature is too high will limit the maximum input current of the led display The above points are the temperature of the introduction of the led display, through the above description that the temperature increase on the led display is a very large impact. So the right and proper temperature is the focus of the led display.

In early July, mobile and package client V4.6 was officially launched. This version of the APP did not change much in the interface, but the background quietly added face recognition technology for high-risk cardholders. Face recognition authentication is based on the general "real-name system" to further strengthen the verification of identity information. In the past, only the identity card number and name were required to know, and real-name authentication could be performed. After joining the face recognition technology, it is necessary for me to carry out real-name operations to successfully pass the certification.

In a word: This is the enhanced version of the "real name system."

The ubiquitous “real-name system” has a long history. How did it develop? Is it necessary?

The "real-name system" has been ubiquitous in our lives. Its existence not only facilitates government management, but also greatly safeguards our property and our lives. The “real-name system” we are talking about now refers to the network real-name system in the fields of mobile phones, the Internet, and banks. In fact, as early as in ancient times, this continent has been groping for "real-name system."

I. Clan Social Period to Western Zhou Dynasty - Named as Real (Name + Biological Characteristics)

"Name" was born during the clan society period. At that time, "surname" was the clan's clan number, and the celebrity was the personal reference. People must be named after they are born to separate them from each other. Otherwise, they cannot enter the existing social order system as independent people.

Because the life span of human beings is generally small during the clan society, people identify each other mainly based on names and biological characteristics (including voice, appearance, body shape, hair style, etc.). A smaller population makes the identification of biometrics more adequate to meet the needs, but as the number of humans increases, duplicative names and easily misidentified biometrics make humans begin to grope for new "real-name systems."

For example, if there is a name called "Heavy China" in Hedong and "Heisei" in Hexi, different clans can also be distinguished by their surnames. When a clan is large, there must be duplicate names in the clan. It is difficult to get rid of household registration information with the same name. Differentiate people.

Second, business to the Qing Dynasty - to the nationality (name + household registration)

According to Oracle records, the Shang dynasty has begun to implement a population registration system, with "departures" or "ascension", that is, records of temporary recruits. The book of "Shangshu Duoshi" said: "Yes, you have a predecessor, there is a book", it can be seen at that time that there are head statistics. This can be regarded as the germination of China's household registration system.

In the Warring States Period, Qin Xiangong promoted the “association of household registrations” and the household registration system began to develop rapidly. During the period of the Southern and Northern Dynasties, the basic framework of the household registration system was formed, and household registrations were classified and audited to inspect the population, levied taxes, transferred labor, and held a national-scale population survey. This framework has been used for the Ming and Qing Dynasties.

The emergence of the household registration system made it possible to manage large-scale populations. It allowed a large number of people to become virtual paper letters, allowing names to correspond with household registration information. To promote the development of agricultural society, while maintaining the stability of society through the shackles of personnel. However, there are no biometrics on the household registration system. They can only verify the authenticity of the household registration information. This has led to the falsification of certain dynasties and serious damage to the national interest.

III. From 1912 to the end of the 20th century - using evidence as evidence (document + household registration)

In fact, since the Sui and Tang dynasties, China had an ID card in the broad sense of the word: “Yu Fu”. In the Ming Dynasty, it used the “Dental Card” with the name, title, curriculum vitae, and tips of the licensee. It is in the modern sense. The card ID is very close.

The earliest identity card system in China should be the "resident card system" formulated by the Ningxia provincial government in 1936. Ningxia Province's "Residential Permit" is made of white cloth, which is 7 cm long and 3 cm wide. It contains the name, age, place of birth, occupation, length, appearance, features, and shape of the hand pattern. "Resident permits" are stipulated in the coats for inspection. Although this "resident certificate" is different from the subsequent national identity levy, it already possesses all the elements of an identity card and is the earliest prototype of a Chinese identity card.

After Japan surrendered in 1945, the National People's Government Legislative Yuan amended the then-current Household Registration Act. In 1946, the Nationalist Government announced the “Family Registration Law (Amendment Draft)” and “Detailed Rules for the Implementation of the Household Registration Law”, which stipulated that the national identity card should be issued and issued. The Chinese citizens who had issued the license must have reached the age of 18 and above, regardless of gender. Under the age of 18, the automatic requester may also be granted a grant. Active servicemen will not be filled out for the time being. Since then, the old Chinese provinces and municipalities under the Kuomintang rule have established regulations for the implementation of identity cards. Since there are no specific unified regulations, the regulations formulated are also not the same.

After the liberation in 1949, Chinese citizens used their residence booklet and the unit's introduction letter for a long time to prove their identity. On April 6, 1984, the State Council approved the Ministry’s notice regarding the issuance of certain resident ID cards, and announced the “Regulations on the Implementation of the Identity Card of the People's Republic of China”. Since then, through the implementation of the resident identity card system, China has unveiled the prelude to the resident account credentials management, and began to issue the first generation of resident ID cards.

China's new anti-counterfeiting resident identity card was opened on July 1, 1995, and the certificate adopted a holographic transparent plastic envelope.

During this period, the identity verification was greatly improved by integrating the ID of the household registration information and manual inspection. However, due to the low degree of automation of detection, lawbreakers bypass detection through tampering with ID cards or using artificial detection error loopholes, and it is not uncommon for them to open bank accounts or commit fraud crimes.

Fourth, since the 21st century - to be human (certificate + biometric)

On March 29th, 2004, the Chinese mainland officially began experimenting with re-issuing second-generation resident ID cards for residents who have built-in non-contact IC card smart chips. The larger scale renewal started in 2005. From January 1, 2013, the generation of ID cards will cease to be used, and the new second-generation ID cards will also register fingerprint information during the application.

In order to further strengthen the management of the "real-name system," the state has continuously issued a new "real-name system" management policy, which requires the elimination of telecommunications and bank "black households" with great security risks. All aspects of social life, such as the Internet, APP, transportation, and hotels, have also begun to promote compulsory "real-name certification."

Biometrics as a natural feature of the human body has the convenience of recognition and irreplaceability. Through the identification of equipment IC chips plus face recognition, fingerprint recognition and other biometric identification technologies, it can ensure the authenticity of the verified person and reduce errors. Risk detection.

Summary

different periods of "real names" have different authentication methods, but in the final analysis, the purpose of "real name" is to confirm the authenticity of his own identity. When existing authentication methods cannot meet the needs, new authentication methods will be used instead.

There is a need for mobile and real-name authentication or other real-name witnesses such as hotels and transportation. Whether it is telecommunications, finance, or the Internet, new methods of fraud and fraud continue to emerge. The “real-name system” can target offenders and greatly limit illegal crimes.

◇Ammonia: the oldest in history, the best choice in the field of industrial refrigeration worldwide. Due to the characteristics of the ammonia system, it is generally used for centralized refrigeration, with a special machine room for large-scale refrigeration systems (more than 10,000 tons of cold storage). There is a trend toward miniaturization and modulation, with an emphasis on improving safety and reducing the amount of charging.

◇ Freon: It is widely used in cold storage to disperse refrigeration. It is suitable for small and medium-sized cold storage and large-scale cold storage with limited ammonia. For environmental protection, large-scale cold storage The Freon system should be avoided as much as possible.

◇ CO2: The cold storage application is mainly based on cascade system and loading system. The low-temperature field is more suitable for cascade. The high-temperature field is suitable for loading. The cascade system is more expensive than the traditional ammonia and Freon system.
