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.

级联型多电平变换器类似于积木化的结构，本文按模块单元的结构形式，将级联型多电平变换器分为相同单元和不同单元两类，以输出最大电平数为目标，系统地分析模块单元个数与最大输出电平数、输入直流电压与最大输出电平数、以及输出电平数与谐波畸变率之间的关系，从中归纳得到构造级联型多电平变换器的指导原则。

Mr Venter said he was "100% confident "the same technique would work for the artficially created chromosome.The new life form will depend for its ability to replicate and metabolise on the molecular machinery of the cell into which it has been injected,and in that sense it will not be a wholly synthetic life form.

这个新生命形式，它将能够复制并对分子机器上的细胞，它已被注射，从这个意义上说，它将不会是一个完全人造生命形式然而，它的脱氧核糖核酸将人造，它是DNA中控制细胞和使用生命积木。

There are two types of switches:'Heavy'X-shaped ones and'Soft'round ones Soft switches are activated when any part of your block presses it.
