Analysis of the main reasons is because of fatigue caused by factors such as the copper support ring was broken and the piston rod in the hydraulic cylinder telescopic frequently, the fracture茬口constantly scraping the inner wall hydraulic cylinder mill will pick缸壁, resulting in injury China, so that the speed of decline in hydraulic cylinder; job with the passage of time, strain and缸壁sealing ring, wear ring injuries are increasing, with China to increase the volume, and finally resulted in a serious decline in the speed of hydraulic cylinders.

分析主要原因是，由于疲劳等因素造成的铜质支撑环断裂，在液压缸活塞杆的频繁伸缩中，断裂茬口不断刮磨液压缸内壁，将缸壁拉毛、拉伤而导致内泄，使液压缸速度下降；随着工作时间的推移，缸壁拉伤和密封环、耐磨环的损伤都不断加重，内泄量加大，最后造成液压缸速度严重下降。

If the boiler check valve hasn't be shut, then must prevent steam and water back to the boiler . With the effect of tgravity, check valve and damper piston can immediately get airproof and the steam and water won't back to the boiler even in an atomosphere of low pressure.

如果锅炉没有关闭截止止回阀，则必须防止回流到锅炉上，阀瓣压铁和缓冲活塞，在重力的作用下，能够迅速实现密封，使得蒸汽和冷凝水即使在低压下也不会回流到锅炉里。

In the process,with the outer diameter and inner diameter dial gauge micrometer accurate measurement of the plunger several times in size and ellipticity,as well as cylinder boreSlurry pumps diameter,taper,so that the piston and cylinder are matching with the clearance hole achieve 0.02_0.4mm requirements.

在此过程中，用外径千分尺和内径千分表多次准确测量柱塞的外径尺寸和椭圆度，和缸体孔孔径、锥度，使所选配的柱塞和缸体孔的配合间隙达到0.02_0.4mm的要求。

At present, the market is no gas spraying machine, there are two types of pump: piston pump and diaphragm pump.

目前，市场上无气喷涂机泵浦的类型有两种：柱塞泵和隔膜泵。

With the piston pump, diaphragm and gear pumps is different is that single-screw pump can be used for pharmaceutical filling and measurement.

和齿轮泵相比，单螺杆泵可输送高粘度的物质。与柱塞泵、单螺杆泵及齿轮泵不同的是，单螺杆泵可用于药剂填充和计量。

Such as: dual-diaphragm, double diaphragm pump alarm, special performance pump, high performance piston pump, the product has been overwhelming majority of customers.

双隔膜、双隔膜报警泵、特殊性能泵、高性能柱塞泵，产品得到广大客户的一致好评。

Finally, several sets of cast dies and molds, including V6 transfer mold emplyed by GM, shoe die and piston die used for Santana, have been casted by LS high precise die-making system. All of these dies only needed a little machinaity. The cost and manufacture period of cast dies are lower than those of traditional wrought dies.

最后，采用LS法精密模具制造技术，用铸铁和新开发的铸造模具钢MCH13钢浇铸了多副模具，如V6发动机曲轴模、鞋模、桑塔纳轿车用活塞模具等，这些模具仅需进行少量的机加工即可进行使用，其生产成本及制作周期大大低于同类传统方法制造的模具。

It together with piston style steam 、The largesttest difference of diesel engine rests with :In the way of the capacity means difference .

它与活塞式汽、柴油机的最大区别在于：用能方式不同。

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。
