| 摘 要： | 提出一个超临界CO2压缩因子实验数据的新的双自变量拟合方程，运用遗传算法优化方程系数，总平均相对误差为1．23％，该方程可直接应用于缔合模型，计算固体在超临界CO2中溶解度。以地西泮在超临界CO2中溶解度为例计算，取得很好的结果。

| Abstract: | A new fit equation with two variables for compressibility factor data of supercritical carbon dioxide was proposed in this article. Parameters of the equation were optimized by using the genetic algorithm. The total average relative deviation resulted from the equation is 1.23 %. The equation can directly be applied to the association model for calculating of solubility of solids in supercritical carbon dioxide. For example, the result of diazepam in supercritical carbon dioxide calculated from the model is very good. |
