| 摘 要： | 从正则系综的基本公式出发，绕开对位形积分的具体计算，结合热力学能态方程，求出了e-1<压缩因子Z0, p0)附近压力与温度的一般解析式，并与实验值进行了对照。应用本文导出的公式在工程热物理方面可减少实验测试的次数，在石化工业中可用来计算环境温度的变化对高压储气罐内压力的影响。

| Abstract: | The pressure-temperature relation is analytically derived for high-Pressure mixed gases with compressibility factor e-1<Z at constant volume in the vicinity of any temperature by using the basic formulae of canonical ensemble as well as thermodynamic equation of state. Applying these expressions to engineering thermophysics can reduce the times of tests, and to oil-chemical industry can estimate the effect of surrounding temperature on the pressurized tank. The calculated results are in accord with the experimental ones. |
