一、前言低温技术是一门发展迅速的现代科学。它为许多技术部门和基础科学服务,并形成许多独特的边缘学科,正在改变一些古典学科的面貌。如超导技术、低温电子学、低温生物学、低温医学等都形成了新的边缘学科,又如低温的金属处理,低温粉碎等形成一个新的工艺方法。现代低温技术是指-162℃(111.7K)以下温度一系列低温技术。因为这一温度有它一定
I. Introduction Cryogenic technology is a rapidly developing modern science. It serves many technical departments and basic sciences and forms many unique fringe disciplines that are changing the face of some classical disciplines. Such as superconducting technology, low temperature electronics, low temperature biology, cryogenic medicine, etc. have formed a new edge disciplines, such as low-temperature metal processing, low temperature grinding to form a new process. Modern low-temperature technology refers to a series of low-temperature technologies at temperatures below -162 ° C (111.7K). Because it has a certain temperature
