提出了硬球流体状态方程的以下近似封闭形式表示[图略]，其中D是维数，Bn是密度相对于紧密堆积的幂展开中的维里系数。使用已知的维里系数m= 6（或7），表达式再现精确的（数值）状态方程数据具有更高的精度比以前的分析和参数形式在两个和三个维度。
The following approximate closed-form representation of the fluid equation of state for hard sphere is proposed [graphic omitted] where D is the dimensionality and Bn are the virial coefficients in the expansion in powers of the density relative to close packing. Using the known virial coefficients up to m= 6 (or 7), the expression reproduces the exact (numerical) equation of state data with a greater accuracy than previous analytic and parametric forms in both two and three dimensions.
