它显示了如何确定计算纯原子气体的粘度和热导率所需的矩阵元素在任意高近似的解玻尔兹曼方程。第一次给出了计算第四次和第五次近似的显式表达式。基于这些表达式的计算机程序已经对各种原子相互作用势模型进行了测试。
It is shown how to determine the matrix elements needed to calculate the viscosity and thermal conductivity of a pure atomic gas in arbitrarily high approximation to the solution of the Boltzmann equation. For the first time, explicit expressions are given for calculating the fourth and fifth approximations. Computer programs based on these expressions have been tested for various models of the interatomic interaction potential.
