| 摘 要： | 在纯物质常沸点汽化热的剩余函数预测法的基础上,结合并改进W-S方程,推导出预测纯物质在任一温度下的汽化热的新方程。由最基本的物性数据T_b,T_c,P_c,预测245种各类物质7574个温度点的汽化热,与实验值相比较的总绝对平均误差为1.77％,优于原剩余函数法。

| Abstract: | Based on the prediction of the heat of vaporization for pure compounds with the method of residual function, a new equation is derived. The equation is combined with and improved from WS equation. With the most basic physical property data T_b , T_c and P_c ,the heat of vaporization of 245 compounds at 7574 temperature points are calculated. Compared with experimental data, the overall absolute average error is 1.77%, which is better than the original method of residual function. |
