Abstract

An alternative approach to calculating the critical nucleus size and the nucleus formation energy has been developed. A significant difference between this method and the generally accepted so-called classical method, according to which a nucleation center begins to form at the melting temperature, is noted. The results are illustrated by the dependences of the nucleus size and the nucleus formation energy on the supercooling and by the Gibbs energy plotted as a function of the nucleus size in both the classical and the proposed versions.

过冷液体均相凝固过程中核尺寸的替代计算

摘要

已经开发了一种计算临界核尺寸和核形成能的替代方法。注意到该方法与通常接受的所谓经典方法之间的显着差异，根据该经典方法，在熔化温度下开始形成核中心。在经典和拟议版本中，核尺寸和核形成能对过冷度的依赖性以及吉布斯能量随核尺寸的变化作图说明了结果。
