本文在提供Schl?gl一级相变化学反应模型中在反映非平衡相变过程的波前(wave front)波形和波速的基础上,提出用扰动匹配方法研究与该相变相联系的核化过程的临界核与临界泡内组分浓度分布和临界半径。In this paper, on the basis of providing wave front solutions to Schl?gl model of chemical reaction concerning first order phase transition, the wave profiles describing the concentration distributions in critical nuclei and bubbles are studied by means of a perturbation-matching method and the approximate values of the radii of nuclei and bubbles are found.
