| 摘 要： | 本文对纯液体沸腾汽化过程的热力学问题用吉布斯自由能判据进行了详细的讨论,指出生成一个球形气泡新相时必须克服一个能峰,而且这个能峰随液体过热度的增大而变小,从而合理的解释了液体沸腾汽化的过热现象。

| Abstract: | The article discuss a thermodynamical question to use Gibbs free energy criterion in a liquid boiling vaporization process,and points out an energy barrier must have been or-ercome when the liquid boiling vaporization changes into a ball bubble new phase, and the energy barrier must decrease when the excessive heating degree is raised, thereby explaining the excessive heating phenomenon in a liquid boiling vaporization process. |
