摘要

著者综合前人计算蒸发潜热的经验公式

诱导出一个新的计算公式如下:λ/T_c=-6.7logP_r(T_r/(1-T_r)~(0.62))任何物质在任何温度T与压力P状态下的蒸发潜热λ

只要有了该物质临界温度与临界压力的数据

就可以根据这个公式计算.式中T_r为绝对温度与临界绝对温度之比

P_r为压力与临界压力之比.此公式的错误小于百分之五.

Abstract

A generalized equation

is derived to calculate the molal latent heat of vaporization

of any substance at any reduced tem-perature

and reduced pressure

with an error generally less than 5%.
