The "500-meter spherical radio telescope" project passed the file acceptance

[ Instrument Network Instrument Development ] On May 27th, the “500m Caliber Spherical Radio Telescope” (FAST) National Major Science and Technology Infrastructure Project passed the file acceptance. Pan Ya-nan, director of the Archives of the Chinese Academy of Sciences, is the leader of the archives professional acceptance team. The acceptance team heard the construction unit's "FAST project file acceptance summary report" and the "FAST project file acceptance application material review report" of the Chinese Academy of Sciences Archives, reviewed the project file self-examination report and related supporting materials, and spot-checked the project file. .

The 500-meter spherical radio telescope is known as the "Chinese Eyes". It was proposed by the Chinese astronomer Nan Rendong in 1994. It was completed in 22 years and was opened on September 25, 2016. It is built by the National Astronomical Observatory of the Chinese Academy of Sciences and has China's independent intellectual property rights, the world's largest single-caliber, and the most sensitive radio telescope. The overall performance is ten times that of the famous radio telescope Arecibo.
As of September 12, 2018, 59 high-quality pulsar candidates have been identified in the 500-meter spherical radio telescope, of which 44 have been identified as newly discovered pulsars. In March 2019, Jiang Peng, chief engineer and researcher of the National Astronomical Observatory of the Chinese Academy of Sciences, said in an interview, and cooperated with the Tianma telescope team to successfully achieve joint observation for the first time, which indicates that FAST has the ability to jointly observe the network.
The acceptance team believes that the FAST project construction unit attaches great importance to the project archives work and establishes a sound file management system; strictly implements the national and Chinese Academy of Sciences project file management norms, and formulates a series of project file management systems in combination with the actual work; The project construction content and the whole process, the integrity, accuracy and system are in line with the relevant requirements of the State and the Chinese Academy of Sciences; the project construction unit has established a digital management system for the FAST project file, which is conducive to the remote storage of files and online inquiry and utilization; the collection of audio and video materials The effectiveness of archiving has been remarkable. The development and utilization of archival resources has greatly enhanced the social influence of the FAST project; the FAST project file meets the acceptance criteria and agrees to pass the archival professional acceptance.

SHMP Food Grade

After Sodium Hexametaphosphate is used in the food industry, it plays the following important roles:

(1) Food grade sodium hexametaphosphate can improve and improve the sensory indexes such as color, aroma, taste and taste of food

The color, aroma, taste, shape and taste of food are important indicators to measure the quality of food. Food processing generally involves physical processes such as grinding, crushing, heating and pressurization. In these processing processes, food is easy to fade and discolor, and the inherent aroma of some food is also lost.
In addition, it is difficult to meet the requirements of soft, hard, crisp and tough taste of products in the same processing process. Therefore, proper use of food additives such as quality improver sodium hexametaphosphate can significantly improve the sensory quality of food and meet the needs of people for food flavor and taste.

(2) It is conducive to food storage and transportation and extends the shelf life of food

All kinds of fresh food and all kinds of high protein food will go bad soon after leaving the factory if no anti-corrosion and fresh-keeping measures are taken.
Food grade sodium hexametaphosphate can ensure the food to maintain its due quality and quality within the shelf life.

(3) Increase the variety of food

The shelves of the food supermarket are filled with a dazzling variety of food. In addition to grain and oil, fruits and vegetables, meat, eggs and milk, these foods also have an indispensable raw material, namely, food additives.
According to the different processing technologies, varieties and tastes of various foods, the correct food additives are generally selected. Although the amount of food grade sodium hexametaphosphate is not large, different varieties can be obtained.

(4) Conducive to food processing operations

In the process of food processing, many needs lubrication, defoaming, filtration aid, stabilization and solidification. For example, adding food grade sodium hexametaphosphate to ice cream can play the role of chelating, changing pH value, emulsifying and dispersing, improving the ionic strength of food, increasing the volume of ice cream and expanding, which is conducive to food processing.

The use of sodium hexametaphosphate in food additives not only increases the variety and quality of food, but also can be used alone; Compound phosphates: mainly composed of sodium hexametaphosphate, Sodium Tripolyphosphate, sodium pyrophosphate, trimethyl phosphate and trisodium phosphate in a certain proportion. The use of various additives such as stabilizers, coagulants and flocculants in the production process can reduce the consumption of raw materials and improve the product yield, thus reducing the production cost and producing obvious economic and social benefits.
