In chapter 4, A precious nonlinear methematic model about the servo mechanism of dynamic test equipment for rod pump is studied.

第四章提出了有杆泵动态测试装置液压伺服机系统的详细数学模型及其简化数学模型。

In general, students are encouraged to explore the various branches of mathematics, both pure and applied.

一般来讲，鼓励学生学习不同的数学分支，包括纯数学及应用数学。

Pure mathematics can be practically useful and applied mathematics can be artistically elegant.

纯粹数学可以是有用的，而应用数学也可以高雅的。

Even fields such as number theory that are part of pure mathematics are now important in applications, though they are not generally considered to be part of the field of applied mathematics per se .

即使等领域的一些理论，是纯粹数学，现在重要的应用程序，但他们不是一般被认为是部分领域的应用数学本身。

This transcendental principle of mathematics makes pure mathematics applicable to objects of experience.

显象的数学的这一先验原理给予我们的先天知识以很大的扩展。因为只有它才使纯粹数学能够以其全部的精确性运用于经验的对象。

If one considers science to be strictly about the physical world, then mathematics, or at least pure mathematics , is not a science.

如果认为必须严格科学的物质世界，然后数学，或至少纯粹数学，是不是一门科学。

The mathematical model of asynchronous motor under the condition of 2 phase quiescency and 2 phase rotating frame is gained, and then the mathematical mode of super dense-phase conveying load is founded.

本文通过矩阵变换得到了异步电机在二相静止和二相旋转坐标系下的数学模型，从而建立了超浓相输送负荷的数学模型。

Transport system is a random nature, ambiguity and uncertainty of complex systems, the establishment of mathematical models very difficult and sometimes impossible to use existing mathematical methods described.

交通系统是一个具有随机性、模糊性和不确定性的复杂系统，建立数学模型非常困难，有时甚至无法用现有的数学方法加以描述。

Transport system is a random nature, ambiguity and uncertainty of complex systems, the establishment of mathematical models very difficult and sometimes impossble to use existing mathematical methods described.

交通系统是一个具有随机性、模糊性和不确定性的复杂系统，建立数学模型非常困难，有时甚至无法用现有的数学方法加以描述。

In the process of calculation ,not only the decouplable feature of symmetrical elements in the coordinate system of symmetrical components is fully utilized,but also the symmetrical parts and unsymmetrical parts are treated as separate blocks, thus the efficiency of calculation is rasied moreover.

建立用于故障分析的网络的数学模型是计算机编程计算的基础。当前在电力网络中最常用的网络参数矩阵有节点参数矩阵和支路参数矩阵。在故障分析计算中一般采用网络节点参数矩阵作为电力网络的数学模型，又主要使用节点导纳矩阵作为分析的基础。

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。
