Measuring the universal gas constant based onthe phase transition

用相变法测定 普 适 气体 常量

The experimental uncertainties in the temperature pressure and the universal gas constant in gases are estimated to be not greater than ± 14 mK 、± 2 kPa and ± 0.0036 % respectively .

实验温度、压力和 普 适 气体 常数的不确定度分别为±14mK，±2kPa和±00036%。

M is the molecular weight of the compound and R is the universal gas constant .

M为分子量； R为 气体 常数。

This quantity is called the universal gas constant .

这个量叫做 普 适 气体 恒量。
