FAST project introduction
The project plans to use the original design of Chinese scientists and the unique terrain conditions of the karst depression in southern Guizhou, my country, to build a high-sensitivity facility about the size of 30 football fields. giant radio telescope.
Using the unique natural karst depression site in Guizhou, applying active reflector technology to correct spherical aberration on the ground, using lightweight cable-drag feed support to reduce the 10,000-ton platform to tens of tons. FAST has the ability to observe neutral hydrogen Extend to the edge of the universe and recreate images of the early universe.
In order to achieve leapfrog development, the Chinese astronomical community proposed to build the world's largest single-aperture radio telescope - the 500-meter Aperture Spherical Radio Telescope (FAST). The world's largest single-diameter radio telescope is in Lushui Village, Kedu Town, Pingtang County, Guizhou Province.
The world's largest single-diameter radio telescope is in Lushui Village, Kedu Town, Pingtang County, Guizhou Province. The world's largest radio astronomy telescope, the 500-meter Aperture Spherical Radio Telescope (FAST), is located in the Dawodang Depression in Lushui Village, Kedu Town, Pingtang County, Guizhou Province, my country. It took more than 20 years from site selection to construction.
The world's largest single-aperture radio telescope is in China. On March 31, 2021, the "China Sky Eye" (FAST) was officially opened to astronomers around the world. What is the "Chinese Sky Eye"? It is my country's single-aperture spherical radio telescope with independent intellectual property rights for exploring the universe.
FAST is the world's largest single-aperture radio telescope - the 500-meter spherical radio astronomy telescope proposed and built by Chinese astronomers. It is located in the "Dawodang" depression in Jinke Village, Kedu Town, Pingtang County, Qiannan Prefecture, Guizhou Province. Construction officially started in March 2011.
The "China Sky Eye" (FAST) is the world's largest single-aperture radio telescope. "China Sky Eye", also known as FAST, is a 500-meter spherical radio telescope. Located in a giant karst depression in southern Guizhou, Guizhou Province, it is currently the largest single-aperture, most sensitive, and most comprehensive radio telescope in the world.
The World's Largest Aperture Radio Telescope (FAST) After completion, FAST will become the world's largest radio telescope. Compared with the 100-meter Telescope in Bonn, Germany, which is known as the largest machine on the ground, FAST is about 10 times more sensitive. What does FAST mean?
1. Fast means: adj. tight (opp. loose), firm, firm, sticky, solid; fixed. Faithful and reliable. Durable; non-fading; resistant (acid, etc.). (Exercise) intense, (sleep) sweet.
2. Fast means: fast. Pronunciation: British [fɑst], American [fst]. Definition: adj. Quick, rapid; tight, stable. adv. quickly; tightly; thoroughly. vi. Fasting, fasting. n. Fast; hunger strike.
3. Fast often refers to the continuous high-speed movement of people or things, emphasizing the way of movement. Instant means that something happens quickly or needs to be solved urgently, which means there is no need to delay. Rapid is more formal than fast and quick. It often refers to the movement itself, focusing on the amazing speed. The action referred to may be brief or sustained.
4. The adverb of fast is fast, and fast can be an adverb, a verb, a noun, and an adjective. Adverbs include: quickly; quickly; tightly; thoroughly; adjectives include fast; go fast. Iran fast into the room. I quickly ran into the room. What is the fast sterilization system?
In Android phones, Fastboot is a lower-level flashing mode than Recovery. It is a flash mode that uses a USB data cable to connect the phone.
You need to install the USB driver suitable for your mobile phone on your computer. In Android phones, Fastboot is a lower-level flashing mode than recovery (commonly known as fast boot mode). Compared with some card swiping systems, online swiping is more reliable and safer.
Haier air conditioners laid out health technology in advance more than 20 years ago, and each step is faster than the development of the industry. For the first time, this standard combines the air conditioner's sterilization of indoor air with the air conditioner's own sterilization, achieving comprehensive sterilization from the air conditioner heat exchanger, air supply system to room air, and replacing the requirement for disassembly and washing.
Electrolyzed water sterilization technology is better. Electrolyzed water sterilization technology mainly electrolyzes ordinary domestic water to form electrolyzed water. The water contains hypochlorous acid, which can achieve the purpose of sterilization. It is efficient and convenient, and is more time- and cost-saving than high-temperature sterilization technology.
The refrigerator has a sterilization function. Here we recommend Midea’s odor-free refrigerator. When I bought this refrigerator, I personally experienced its sterilization and odor removal function. At that time, the shopping guide opened a durian perfume box and placed it in the odor-free refrigerator. After about 20 minutes, when he opened the refrigerator, he could hardly smell the durian smell.
Equipped with a pasteurization system, there is no need to add disinfectants, effectively sterilizing while avoiding chemical residues. Wash and protect at a constant temperature of 60℃-65℃ for 30 minutes. It is the same as the food-grade physical sterilization method of milk. It is unique in the industry and has a deep sterilization rate of 99%.
