积木化

According to characteristic of parallel mechanism and the different control rule between traditional NC machine and parallel NC machine , the CNC system with open modular architecture has been set up. Because the software module and hardware module have been designed based on standardization and diversification, the deviser can set up system with different module such as building block.

根据并联实验平台的结构特点以及它与传统机床控制规律的不同，本文采用开放式、模块化体系结构建造数控系统，在标准化与多样化的基础上设计了软、硬件模块，这样就可以通过加减配置不同的模块来构造数控系统，实现系统"积木式"的集成。

It uses the building block system structure, the modular design, the implementation unification standard, versatilely satisfies the intellectualized building to be highly effective, reliably, the flexible request.

它采用积木式结构、模块化设计、实施统一标准，完全能满足智能化建筑高效、可靠、灵活性的要求。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
