液氦冷卻 的英文怎麼說
中文拼音 [yèhàilěngquè]
液氦冷卻
英文
liquid helium cooling-
When helium is cooled to very low temperatures, it forms an astonishing liquid.
當氦冷卻到很低溫度時，它會形成一種奇妙的液體。Two of liquid metal materials, i. e. liquid metal pb - 17li and li, are seriously considered for their physical and chemical properties. liquid metal pb - 17li is one of the most attractive candidates for using as breeder, neutron multiplicator and coolant in dual - cooled waste transmutation blanket of fds
分析了有關液態金屬材料的物理化學特性，經過綜合慎重考慮和研究，選取液態金屬pb - 17li作為氚增殖劑和中子倍增材料，同時也作為冷卻劑和氦氣在包層中分離冷卻。Consequently, the first chip - trap proposal, put forward by a group at the california institute of technology in 1995, involved cooling the entire chip to near absolute zero using a bulky and expensive liquid - helium refrigerator
所以， 1995年加州理工學院的一個小組首度提出晶片阱的構想，需要用龐大且昂貴的液態氦冷凍機，將整個晶片冷卻到接近絕對零度。Especially, in the filed of high tc superconductor, the technology that the cryocooler directly cool the superconducting system has changed the traditional cooling manner, which adopts the method of low tc fluid helium ' s convection and boiling to exchange the heat. it mainly depends on the cooling manner of conducting heat through the interfacial layer between the material of superconductor and non - superconductor ( such as cu, isolator, etc )
特別是在高溫超導領域中，由於製冷機直接冷卻技術改變了傳統的靠低溫液氦對流、沸騰換熱的冷卻方式，主要依靠超導材料與非超導材料（如銅、電絕緣材料等）固體間的接觸導熱冷卻方式，固體間界面熱阻成為影響導熱性能的關鍵因素之一。It would not make sense to inject that much power into one point of the grid, and liquid helium is a cumbersome coolant
在電力網的某個點，輸入那麼大的電力沒什麼意義，液態氦這種冷卻劑也不容易處理。分享友人
