| 摘 要： | 主要研究了环境压力对低温容器蒸发率的影响。在理论分析的基础上,使用容积为180L高真空多层绝热的低温容器,以液氮作为充装介质对5组不同环境压力下的蒸发气体量进行测量。结果表明,容器的蒸发率随环境压力的升高而增大,汽化潜热的是影响蒸发率变化的主要因素。为修正大气压力对低温容器蒸发率的影响起到了参考作用。

| Abstract: | This paper summarized research on the effect of vapor pressure on the evaporation rate of cryogenic vessel.On the basis of the theoretical analysis,a 180L multilayer-insulation vessel filled with liquid nitrogen was used for measuring the evaporation under five of vapor pressure.The results showed that the evaporation rate increases with the vapor pressure and the latent heat plays an important role.It provided reliable references for correction the effect of pressure on the evaporation rate of cryogenic ve... |
