摘要/Abstract

摘要： 在气体输运过程中，把气体分子看作有引力的弹性球，研究了分子力对气体输运系数的影响，对普通物理中的气体动理论给出的输运系数与气体温度的关系进行了修正，使之更接近于实验结果.

关键词: 气体输运系数, 有心力模型, Lennard—Jones势, 有效碰撞截面

Abstract: Considering molecules as elastic particles with molecular attraction in the transport process of gas, the effect of molecular force on transport coefficients is studied. The relation obtained through kinetic theory of gas in general physics between transport coefficients and temperature is modified, the modified one approaches experimental value better.

Key words: transport coefficients of gas, central force model, Lennard-Jones potential, the active section of collision
