摘    要:在Jeans提出的速度住留概念的基础上,引入了速度“反住留”、分子“接续运动”等一些新概念,并由此对Jeans的速度住留理论作了合理引申,得到分子速度的各级有效住留及相应的“等效分子自由程”L.最后,用L代替分子自由程l,使用于气体的初级输运理论,结果表明经过完善化了的速度住留理论是相当成功的。

关 键 词:速度住留  细致平衡  气体分子输运

Abstract:Based on the Jeans's theory of persistence of velocity,a number of new conceptions,such as inverse persistence of velocity and successive movement of molecules and so on,is presented.The theory on velocity-persistence is extended.The available persistence of velocity at different levels and the corresponding equivalent free path of the molecule L are obtained.Finally,when L takes the place of l,good results are got with the elementary theories of the transport phenomena.This shows that,the completed theory of persistence is a success.
Keywords:persistence of velocity  detailed balancing  molecular transport of gases
