该文介绍了一种组合式液氦恒温器的原理、结构和初步实验结果。它用G-M制冷机将液氦恒温器的幅射屏及热支承处冷却至85K以下,使外界传入的热量为最少,以足够低的液氦蒸发率使液氨得以长时间保存。
This paper introduces the principle, structure and preliminary experimental results of a combined liquid helium thermostat. It uses the G-M refrigerator liquid helium radiator radiating screen and the heat support at 85K below the heat transfer to the outside world for the least, with a low enough liquid helium evaporation rate of liquid ammonia can be stored for a long time.
