在低温实验中,经常需要通过控制低温杜瓦容器内液体的蒸汽压力,从而达到控制温度的目的。这里介绍一种简单实用的蒸汽压调节器,它可以满足实验室使用的要求。
In low temperature experiments, it is often necessary to control the temperature by controlling the vapor pressure of the liquid in the dewar. Here is a simple and practical vapor pressure regulator, it can meet the requirements of laboratory use.
