建议用推广的恩斯柯克方程(14),讨论稠密气体中的输运现象。指出空间关联函数Y(r)可以从状态方程的维里展开求得。文中给出了计算方位势稠密气体的粘滞率和热导率的公式以及计算关联函数的方法。用得到的结果,计算了温度为173K和348K的氩的粘滞率和温度为183K和348K的氩的热导率。在高密度区,计算结果与实验测定的符合程度,较之现有理论,有明显的改进。In order to discuss the transport phenomena in dense gases, a generalized Enskog's equation is suggested. We notice that the correlation function Y(r) can be obtained from virial expansion of the equation of state.In this paper, formulas for calculating viscosity and thermal conductivity for dense gases of molecules interacting with a square-well potential are derived. Using these formulas, we have calculated the viscosity for argon at temperatures 173 K and 348 K and the thermal conductivity for argon at temperatures 183 K and 348 K. Comparison of theoretical results with the experimental measurements shows that the agreement is good and is better than another theoretical calculations made so far.
