【摘要】 根据气体输运过程中黏性现象、热传导现象和扩散现象这三种现象的共同特征,建立气体输运过程模型的合理简化假设,简化了碰撞过程,并应用其推导气体的输运系数,使原来比较复杂的问题简单明了,便于理解和应用。更多还原

【Abstract】 Gas transport process includes three kinds of phenomena—viscosity,heat conduct ion and diffusion. According to the common characteristics of the three kinds of phenomena,a reasonable assumption followed in the transport process is derived. Using the assumption,the derivation process of gas transport coefficients come simple and clear.更多还原
