本文主要介绍贮槽夹层中的珠光砂含水量与真空度的关系,要提高珠光砂的绝热性能和真空度必须对残余气体的含水量进行监测,以达到低温液体的最小蒸发率。
This paper mainly introduces the relationship between the moisture content of pearlescent sand and the degree of vacuum in the interlayer of sump. To improve the adiabatic performance and vacuum degree of pearl sand, the residual moisture content must be monitored to reach the minimum evaporation rate of cryogenic liquid.
