At the same time, this mechanically stable connection safeguards the pressure connection, without additional pipework.

同时，机械稳定连接保护了压力连接，不需要额外的管件。

Mechanical properties of soil including resistance to pressure, shearing, and deformation, internal pressure in relation to soil moisture content were studied with model experiment of paddy soils in rice stubble field and in wheat stubble field under laboratory condition.

在实验室条件下，模拟稻茬和麦茬两种土壤状况，研究了抗机械强度、变形性质和内压力三者与土壤含水量的关系。

When we cover the film, the machine was started tensility there is a slight increase in the number and then remained stable.

当我们覆了膜，机械开动后不压力有一个惨重的补充，然后保留安稳。

When the specimen is pr essed cracked, the instrument automatically stop loading, and

器自动控制机械部分加载，当加载至试件破碎时，仪器自动停止加载，自动记录下此试件的最大压力

"Hydraulic safety valve" is now widely used in hydraulic power systems and hydraulic equipment in the safety device could also serve as limited pressure device, is a special valve, unlike conventional valves, conventional valves with mechanical metal spring as a driving force, can only be limited to low pressure, the pressure encountered over more than 10Mpa limit pressure can do to increase the volume of the Safety Overflow Valve booster design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

&气动液压安全阀&是目前广泛应用于液压动力系统和液压设备中的安全装置，也可以作限压装置，是一种特殊的阀门，它不同于传统的阀门，传统阀门用机械金属弹簧为动力，只能限中低压力，遇到超过10Mpa以上的压力限压，只能做加大体积的增压设计，因此传统阀门作用于高压和超高压的液压动力系统和液压设备的限压时必然体积笨重，结构复杂，制造难度大，产品成本高；在使用过程中金属弹簧的疲劳变化大使限压参数波动大，要经常调整才能保证正常使用。

More unusual is a multi-function display , in the center of the dash, that not only gives a detailed log of the driving behavior - speed, g-force, fuel economy etc - but also gives details of the car's mechanical information (turbo boost, water and engine oil pressure, transmission oil, front/rear drive distribution etc) plus steering angles, braking and acceleration pressure, and also optimal gearshift mapping for best fuel economy.

更不寻常的是一个多功能显示器，在该中心的赛跑，不仅给出了详细的日志的驾驶行为-速度， g力，燃油经济性等-而且还详细介绍了汽车的机械信息（涡轮增加，水和机油压力，变速器油，前/后座径分布等），另加督导的角度，刹车和加速的压力，也优化变速映射为最佳的燃油经济性。

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。
