| 摘 要： | 基于热力学热压理论，推导出了纯物质的气化热方程，用此方程计算了３２ 种物质，其中包括某些强极性化合物，例如甲醇、乙醇和乙酸等的气化热数据。计算数据和实验数据间的一致性十分令人满意。表明此新气化热方程非常适合于描述气液相变化的特性。

| Abstract: | Based on the thermodynamic theory of thermal pressure,the equations for vaporization heat of pure substances were derived,and then used to calculate the vaporization heat data for thirty two substances including some strongly polar compounds,such as methanol,ethanol and acetic acid etc.The agreement between calculated and experimental data was quite satisfactory.It shows that the new equations of vaporization heat herein are well suited to describe the property of vapor liquid phase change. |
