在自然界中硫化物晶体的种类较多，其结构较复杂，其中硫离子以S2-和对硫S2-2形式存在．一部分晶体的生长习性得不到满意的解释．本文采用配位多面体生长习性法则合理地解释了MoS2、ZnS、CuFeS2和PbS晶体的生长习性．发现MOS2晶体的生长习性为六方平板状｛0001｝，其各晶面的生长速度为：V＜0001＞＜V＜1010＞；CuFeS2和ZnS晶体的生长习性为四面体，其各晶面的生长速度为：V＜111＞＞V＜001＞＞V＜111＞；PbS晶体的生长习性为八面体｛111｝，立方体只是它的一种习性变化.
There are many kinds of sulphide crystals in the nature. Their crystal structures are complicated in which
S ions exist in the form of S2- and S22-. Of them, the growth habit of some crystals is not explained successfully. In this paper, the growth habit of
MoS2，ZnS，CuFeS2 and PbS were reasonably explained in terms of the coordination polyhedron rule. The growth habit of MoS2 is hexagonal platy {0001}. The
relationship between different crystal faces in growth rate is: V<0001><V<1010>; the growth habit of the CuFeS2 and ZnS
crystals is a tetrahedra. The relationship between different crystal faces in growth rate is: V<111>>V<001>>V<111>；the growth habit of
PbS crystal is an octahedron {111}, its habit change is a cube.
