摘要
分步结晶是一种历史悠久的金属精炼方法．随着科学与技术的不断发展，分步结晶作为一种独立的热分离过程，对金属熔体的分离与精炼具有日益重要的意义．本文将详细讨论该方法的基本概念、特点及其热力学原理．
Fractional crystallization from the melt is a long standing method for metal refining. As science and technology invariably make constant progress, fractional crystallization is gaining importance as independent thermal process in the separation and refining of the melt. Its basic concept and physico-chemical fundamentalsare systematically discussed in this paper.
