| 摘 要： | 本文利用高阶集团展开方法（三阶），求出二元系统配分函数的表达式。由配分函数求出二 元系统的物态方程。结果表明，当系统堆垛分数在０．０５到０．２５之间时，得到的物态方程与计算机模拟结果基本一致，优于二阶集团展开、Ｐ－Ｙ近似的结果。

| Abstract: | In this paper, by using higher term virial expansion method , we get the expression of partial function for Hardsphere system. Then the equation of state for binary system is developed. The result shows that when the volume fraction change from 0.05 to 0.25 the equation of state we got almost the same result from computer simulation and it is better than the results from lower term virial expansion and P-Y approximation. |
