气体输运过程新理论的研究

A Study on the New Theory for the Transportation Process of Gases

在两个主要假设的基础上直接得到了新的近似分布函数──合成分布函数。把这个新函数用于输运系数的计算时，得到了正确的表达式。如果以等效自由程“Ｌ”代替合成分布函数中的麦氏自由程“ｌ”时，该分布函数将变得更为精确。

Starting from the two assumptions concerned, a new approximate function, the composed function of distribution, has been derived. Applying this new function to the calculation of the transportation coefficient, the correct expressions have been obtained. Furthermore, the composed function of distribution will be more accurate if the Maxwellian free path 'L' is substituted for the equivalent free path 'l' .
