Vector diagram of motor is the important foundation on designing winding spread scheme and testing motor wiring correctness.

电机向量图是设计绕组展开图和测试电机接线正确性的重要依据。

From the basic principles of the AC machine,using the equivalent analysis method, a series of the equations、vector diagram、equivalent circuits of BDFM were obtained, which is the foundation of the analysis and control of the BDFM wind power generation system. The variable structure control was first used to the active and reactive power decoupling control of the BDFM.

无刷双馈电机的功率绕组、控制绕组、转子绕组的极对数不同，电流的实际频率也各不相同，论文从交流电机的基本理论出发，采用等效的方法，得到了无刷双馈电机的基本方程式、向量图和等效电路。

Thus this paper first introduces a general approach to continuous element methods for one-dimensional structures,in which the continuous element methods is computed numerically and directly from the transfer matrix from the state vector equation of motion of a structure.

因此，介绍一维结构的连续单元法的一般方法：由结构运动方程建立状态向量方程和利用单元传递矩阵得到单元的刚度矩阵。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
