"Hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment of safety devices, pressure devices can be limited, is a special valve, which is different from the conventional valve, the traditional use of mechanical valves metal spring as a driving force, can only be limited to low pressure, encountered more BALANCING VALVES than 10Mpa pressure limit pressure can do to increase the volume of pressurized 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，闸阀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。

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.
