晶体结构可分解为若干层次,在最基本的层次中,晶体结构是根据组成原子的相对分布或阳离子和阴离子组成的多面体配位体来描述的。然而,许多结构族可用较大的基本结构单元或模块来描述,这种现象日益明显。若采用该方法来近似描述晶体结构,则许多复杂的固体可依据简单的亚单元的堆垛变化序列来加以系统化。这一方法是lto(1950)在其矿物多型性分析中首先提出的,许多作者在他们的矿物学 Crystal structure can be decomposed into several levels, in the most basic level, the crystal structure is based on the composition of the relative distribution of atoms or cationic and anionic polyhedron ligands to describe. However, many structural families can be described by larger basic building blocks or modules, which is becoming more apparent. If this method is used to approximate the crystal structure, many complex solids can be systematically based on the sequence of stacking changes of simple subunits. This approach was first proposed by lto (1950) in its mineralogical analysis, and many authors in their mineralogy
