Crystal morphology and growth mechanism of sphalerite crystallites were studied by formulating the mathematical model and calculating the stability energy of the growth units on the basis of the theoretical model that the growth units are polyhedral structure of coordinative anions 摘要本文从负离子配位多面体生长基元模型出发,建立了闪锌矿晶体生长基元的数学模型,通过对闪锌矿晶体生长基元稳定能的计算,讨论了闪锌矿的结晶形态和生长机理。
