摘 要:
在低温环境（-196℃）中，低温阀门用弹簧、波纹管等弹性元件的刚度特性将发生变化．并直接影响阀门的低温工作性能。为此，对低温下弹性元件的刚度特性进行专项研究，并掌握了低温下弹性元件刚度变化的一些特点及规律。[著者文摘]

Abstract:
Under the lowtemperature （ - 196 ℃ ）, the rigidity of such elastric elements as spring and bellow in the cryogenic valve will change inevitably and affect the valve working performance. The rigidity change under the cryogenic circumstance was studied and some rules of rigidity change were found. Key words：[著者文摘]
Key words:
