Macro-structures include alluvium predominated structure, multiple-binary-rhythm structure, thick boulder and gravel structure, saccate buried valley structure and tremendous composite structure, fine structures homogeneous structure, stuffed structure, porphyro-structure, and space frame structure, microstructures cemented, semi-cemented and loose texture.

利用第四纪构造与气候环境演变控制论的观点，在成因分类的基础上，对覆盖层进行了结构工程分类，按沉积相的不同组合特点分为冲积为主的结构、多重二元韵律结构、厚层漂卵石层结构、囊状槽谷结构、巨厚复合加积结构等五种类型；按颗粒组成和结合状态，分为均匀型、充填接触型、斑状型和架空型四种细观结构；按胶结成岩状态分为胶结、半胶结和松散三种微观结构。

Cascade multilevel converter is made up of modules. It can be normally divided into two kinds: one with same modules and the other with different modules. This paper analyzes the relationship among the maximum number of output voltage level, the number of cascaded modules, and the input voltage ratio and THD of output voltage in different kinds of cascade multilevel converter. Then, some guidelines for making up cascade multilevel converter are given.
