摘要
采用简化假设的理论和考虑到气体分子自由程的分布及麦克斯韦速度分布律的初级理论这两种方法近似计算输运系数 ,并指出简化假设理论与实际情形的差异 ,同时就简化假设理论能得到与精确程度较高的初级理论相同结果的原因进行讨论。
Transport coefficient is approximately obtained through adopting the simpliried hypothesis theory and through considering the preliminary theories of both the distrobution of free paths of gas molecules and Maxwell's Velocity Distribution Law,then ,the writer points out that the simplified hypothesis theory is somewhat different from the actual situation in application.Meanwhile,the writer explores the reasons why the simplified hypothesis theory produces the same results as the preliminary theory of more accuracy does.
