气体的输运过程与输运系数

Transport process and transport coefficients in gases

根据气体输运过程粘滞、热传导和扩散这三种现象的共有特性 ,推导了输运过程遵循的共同规律 ,给出了推证气体输运系数公式的一种方法 ,避免了热学教科书中对三种输运现象分别进行讨论带来的麻烦。

Gas transport process includes three kinds of phenomena-viscosity, heat conduction and diffusion. According to the common characteristics of the three kinds of phenomena, a common regularity followed in the transport process is derived, and a method of deriving the formula for transport coefficient is given. A lot of trouble is saved, for it is unnecessary to discuss the three kinds of phenomena in the transport process respectively.
