In this paper the commutate circuit principle and work process of the commutate circuit, the composing and work principle of frequency conversion circuit, main switch element IGBT structure feature turn on and turn-off process dynamic and static switch feature and the work principle of invert were analyzed .

本论文分析了整流电路及相控电路的原理和工作过程；变频电路的组成和工作原理；主开关器件IGBT的结构特点、导通及关断过程、动态静态开关特性；逆变电路的工作原理。

The technology of error compensation based on Multi-Body system and the design method of cam machining were combined together.

针对精密凸轮加工中存在的精度问题，推导出凸轮磨削中的理想砂轮中心包络线的求解方程，进而将基于多体系统理论的误差补偿技术与凸轮加工设计方法相结合，研究了理想数控指令的生成方法、砂轮轮廓误差的计算方法、精密数控指令和逆变凸轮廓型的求解算法，在此基础上，开发出凸轮精密磨削过程的误差补偿与动态仿真分析软件。

As we acquire more knowledge, things do not become more comprehensible, but more complex and more mysterious.

当我们获得越来越多的知识，事情并没有变的更加透彻，相反是变的更复杂更神秘。

Central inverter is generally used in large-scale 3-phase PV installations, where strings of PV modules are connected in parallel necessitating complex DC cabling.

中央逆变器一般用于大型的3相逐装置，如串的光伏组件连接在与此同时，迫切需要对复杂的直流电缆。

In the other words, the influences of the winding's current cannot be think about by simply add these influence elements of these windings, the inductance of every winding becomes a complex equation which connected with the currents of all the windings and the permanent magnetic magnetic-force.

永磁磁动势的大小不变，但是转子位置改变时，对各相绕组的轴线的磁通路来说，永磁磁动势的作用便不一样，因此永磁磁动势的影响可以用电感与转角有关来描述。

It was the first time political power, as represented by coinage, was connected to a set of unchanging universal ideas rather than a person.

这是人类历史上第一次，硬币体现的政治权力与一整套恒久不变的普遍观念相联系，而非与任何个人

Stic is the separation of the ownership and the right of management, and the relationship between the owner and the operator is consigner and deputy. Because it has large amount of shareholders, the relation between persons who are correlated with the interests become more complicated, the dilemma of corporate governance exists almost all companies.

股份公司的一个主要特点就是公司的所有权利经营权相分离，所有者与经营者之间是"委托——代理"的关系，股份公司的股东数量很多，公司的不同利益相关者之间的关系变得复杂化，公司治理的问题也就产生了。

Decimal time and longitude would then correlate directly without the need for logarithmic conversion tables.

这样一来，十进制时间就会与经度直接相关联，对数转换表就变得不需要了。

This system uses a cubic phase element and digital image processing to increase the depth of focus in keeping the same illumination and resolution.

设计了一个光学/数字成像系统，该成像系统利用三次位相元件辅以数字图像处理技术，在保持系统光通量及分辨率不变的前提下，提高了光学系统焦深。

The variable reluctance motor is practisely a synchronous motor operated as a brushless D. C. motor with electronic commutation.

变磁阻电机实际上是一种具有电子换相的，以无刷直流方式工作的同步电机。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
