摘    要：在样品的Ｘ射线分析和化学动力学基础上，研究了2201及2212超导相形成的动力学曲线与方程，论证了前者是后者形成的主体，指出了总反应表观活化能是控制超导相形成的主要因素。

Abstract: Based on the results of X-ray diffraction measurement and the theory of chemical kinet-ics,the kinetic curve and equation were established for 2201 and 2212 phase respectlvely in Bi-based superconductor.It is elaborated that the two superconducting phases are formed byconsecutive reactions,and the former is successively the main reactant for the latter。
