非理想气体的第二维里系数及物态方程

The second virial coefficient and the state equation of nonideal gases

利用ＭａｙｅｒＵｒｓｅｌ集团展开法及两体作用的Ｍｏｒｓｅ位势，计算了非理想气体的第二维里系数及物态方程．结果表明第二维里系数和物态方程中的参数都是随温度变化的函数，这一结论与实验相符．

Using the Mayer and Ursell cluster expansions and the tow bodies Morse potential energy,we deduced the second virial coefficient and the state equation of nonideal gases.The concolusions agreed with the experiments.
