universal gas

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%。

This quantity is called the universal gas constant.

这个量叫做普适气体恒量.
