多晶型体的判据式

Discriminant of Polymorphism

本文在文献〔1〕的基础上进一步列举并归属了“同素异形体”与“多晶型体”的实例,并利用晶胞参数提出了判断同一单质的不同形态是否为多晶型体的三个判据式。

In this paper, based on the ref. [1], furtherly enumerate and induce some actual examples about alltrope and polymofph in simple substance , and suggeste three criteria which be used discriminate the different forms of same simple substance is polymorph or not , in the light of the parameters of unit tell.
