This paper analyzes the factors that affect the performance of silicon oil fan clutch and the key configuration.A kind of silicon oil fan clutch has been developed,performance and experimental data of silicon oil fan clutch are summarized through bench testing.The test results show that the optimized clutch can make a response to temperature and has less consumption of power.

硅油风扇离合器不仅可以减少发动机有效功率的损耗，改善发动机的经济性，提高发动机寿命，而且能有效的降低发动机噪声，具有广阔的应用前景[1]。1结构及工作原理硅油风扇离合器是用硅油作介质，利用硅油高粘度的特性来传递转矩，其结构如图1所示，当发动机负荷增加时，水温升高，从散热器吹来的热空气使双金属感温片受热而扭转变形，带动阀销一起转动并通过感温片变形量的大小控制进油阀开度。

选择与环境友好的"洁净"的反应介质是绿色化学研究的重要组成部分。

This flux in fracture system drawing by tectonic stress is a pressured pipe flow, and may be described using Bernoulli's equation according to fluid mechanics.

论证了地质流体因其性质和所处地质环境的不同，可划分为多孔介质中的渗流和较宽阔裂隙中的管流两种。

This model was solved by using the methods of separating-variables and Bessel function, and obtained the analytic solution of pressure distribution for one dimension and unsteady state.

并进而提出负压区的存在不仅与反吹的结构有关，而且和多孔介质本身的性质有关。

This method was based on rotation formula of the current magnetic field and the magnetic fields can be expressed by a double integration about spatial radial coordinate and spatial wave number of Bessel function.

由电流磁场的旋度公式出发，推导了多层介质中点电流源磁场的表达式，其为一个关于空间径向坐标和贝塞尔函数空间波数的二重积分。

Baking soda, on the other hand, is pure bicarbonate of soda.

泡大粉是干燥和酸化的介质，最有代表性的就是酒石粉也叫塔塔粉和淀粉。另一方面小苏打则是纯重碳酸盐。

Internet is a kind of medium, cannot be media purely, must bind together with other media.

互联网是一种介质，不能纯粹是媒体，必须和其他的媒体捆绑在一起。

In chapter 3, the power-law and Bingham fluid flow in porous media are studied.

Utilizing biological technique on modification of them was emphasized and the choices of reaction. activity and biocatalyst by biological method were introduced.

重点介绍了生物技术方法对其改性的优越性及在生物改性过程中反应介质、水活度、生物催化剂选择上所面临的挑战。

On the study of mechanism for attitude of phosphorus in soil in third part and a highlight on the problem of phosphate fertil- izer-biomass production relation and biogeochemical cycle .

所述内容中，重点在二、三两部分，其中第三部分中的当前磷索研究的现状，侧重于机理方面的研究、注重于磷肥—生物产量相关性问题的研究、注重其与不同介质中的生物地球化学循环方面的研究。

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.
