我们应用最近提出的累积量方法来推导二维和三维麦克斯韦分子气体混合物的产生项。对于单组分麦克斯韦气体,我们引入了产生式项的线性近似,并给出了(空间)均匀情况的解析解。我们发现线性化产生式的特征变量以三种不同的形式出现,前几种可以与经典热力学量相关。
We apply the recently proposed cumulant method to derive the production terms for a mixture of gases of Maxwell-molecules in two and three dimensions. For the single component Maxwell gas we introduce a linear approximation of the production terms and give an analytical solution for the (space-)homogeneous case. We find that the eigenvariables of the linearized productions appear in three different kinds and the first few can be related to classical thermodynamic quantities.
