摘要： 笔者首先介绍了单组分物质在气液固三态之间的转变，然后介绍了在二元溶液体系中如何采用类比移植的方法进行科学研究，接着介绍基于这一方法对多组分体系高分子的相分离和结晶所展开的研究，两种相变的相互作用揭示了高分子相变复杂性的真谛。

Abstract: The paper first introduced phase transitions among gas, liquid and solid states in the single component substance, then introduced how to apply the method of transplantation in the scientific research of binary mixtures according to their resemblance to the singlecomponent substance. The method was also applied in the study of polymer phase separation and crystallization in multicomponent systems. The interplay of two phase transitions reveals the complexity of polymer phase transitions.

Key words: polymers, thermodynamics, phase separation, crystallization, complexity
