摘要
本文应用热力学和相变理论导出了在高压静电场下水蒸汽凝华成核的力学平衡、相平衡条件、成核的临界半径、以及饱和蒸汽压方程。该方程说明在强电场中水蒸汽的饱和蒸汽压将随电场强度的增加而减小的规律,定性地解释了在电场中水蒸汽在固体冷表面上凝华成核结霜的规律,并由实验得到证实。
On the basis of thermodynamics and phase transition theory,this paper
deduces the conditions for mechanical equilibrium and phase equilibrium,critical
radius of nucleation and equation of pressure of saturated vapour in a strong
electrostatic field.
The obtained equation shows that saturated vapour pressure increases with
electric field intensity applied,and qualitatively explains the nucleation and frost
formation on the cold solid surface under an electric field,which is proved by
experiments.
