摘　　要：本文根据ＤＴＡ实验测得的降温曲线上的放热峰，探讨了Ｂｉ－２２２３相高温超导体的结晶过程及其温度特性曲线，相变的宏观特征与宏观动力学特征．结果表明，用热分析方法研究高温超导体结晶过程中相变的宏观特征及其规律，对实用化成材的热处理工艺技术有着积极的实践意义．Abstract In this paper,on the basis of the exothermal peaks on thecooling curves recorded during DTA experiments, a discussion is made on the phase transformation process of Bi-2223 phase superconductors andtheir temperature characteristics curves with regard to themacroscopic properties and macro-dynamic features of the transformation.Practice shows that DTA method is effective in research the macroscopic properties and regularities of the transformayion during the crystallization of high temperature superconductors,and is of significance for determining the heat-treatment system for commercoalized superconducting materials.
