Fixed ball valve closed piping system in various types of media used to cut off flow or access to media in accordance with the procedure is scheduled to be transmitted to the various designated points.

固定球阀密闭在各类管路系统种用于截断或接通介质流，使介质按照预定的程序输送到各个指定点。

In the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, medium passed, will not cause the erosion of theAutomatic Control Valves valve sealing surface.

在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

In the fully open and full closed when the ball and valve seat sealing HQ41 sliding path roller type check valve and the dielectric isolation, high-speed through the valve sealing of the medium will not be eroded.

在全开和全闭时，球体和阀座的密封面与介质隔离，因此高速通过阀门的介质不会对密封面侵蚀。

A novel SOI high voltage device with a compound dielectric buried layer is proposed,and an analytical model for its electric field and potential is established.A unified criterion of RESURF condition for CDL SOI and a uniform dielectric buried layer SOI device is given.

提出复合介质埋层SOI(compound dielectric buried layer SOI，CDL SOI)高压器件新结构，建立其电场和电势分布的二维解析模型，给出CDL SOI和均匀介质埋层SOI器件的RESURF条件统一判据。

In this paper,the mechanism of TSC and parasitic conduction current is discussed.

热刺激电流法是在研究介质物理的基础上建立发展起来的，可用于研究介质的微观分子运动[3，4]。

Non-linear dielectrics are the insulation dielectrics whose electric conductivity or/and relative dielectric constant change with electric field.

非线性绝缘介质是指其电导率或相对介电常数随电场变化而变化的绝缘介质。

Based on the basic diffusion theory, the general model of the contaminant transport in the environment is presented.

然后从最基本的扩散理论入手，建立了污染物质在环境介质中传输的通用模型，再结合土壤这一特定的环境介质，对传输模型进一步深化，得出能准确地表达出污染物在各种土壤条件下的运移过程的数学方程，并给出了各种典型情况下的解析解。

Combined with the boundary continuity condition between two kinds of two-phase medium, this finite-element method is facilitated to compute the seismic response of layered model.

文中首先推导了黏弹性双相介质的显式有限元表达式，并编制了程序；给出了黏弹性双相介质交界面的连续条件，这样就可以方便地应用于分层地质模型的计算。

Numerical methods based on the continuum hypothesis and molecule kinetic theory are performed to investigate the gaseous flow in the microchannels. The validity of different boundary conditions based on continuum model is examined by DSMC method under different Knudsen number. It is found that the impact of rarefied and compressibility effects are different.

针对微槽道中气体流动的特征，分别采用连续介质模型和分子运动模型简要分析了连续介质模型中不同滑移边界条件的适用范围，并总结出稀薄效应对槽道中压力的的影响和可压缩效应的作用趋势是相反的。

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。
