molecular speed meaning in Chinese

分子速率
分子运动速度

Direct measurements of the distribution of molecular speeds have been made by a number of methods .
分子速率的分布可以用几种方法来直接测定。
The gravitational field only causes the difference of the number of molecules at different heights , and the distributive regulation of molecular speed has nothing to do with the existence of the gravitational field
重力场只引起分子数在不同高度的差异，分子速度分布的规律与重力场的存在与否无关。
Abstract : an analysis of the numerical properties of maxwell distribution law of molecular speed has been made from the viewpoint of mathematical statistics and the detailed numerical results are given for describing molecular behaviour
