A radial plunger type diffluence motor is used to distribute hydraulic oil to ensure amount of inlet oil is basically equal to that of outlet oil for each servomotor hydraulic cylinder.

分流马达采用径向柱塞式，对液压油进行分流，以保证每个接力器液压缸进出油量的基本相等。

It has solved the problem that the rod was broken and unscrewed.

研制了系列驱动螺杆泵专用抽油杆，解决了螺杆泵采油井所用的普通抽油杆柱断脱率较高和螺纹脱、撸等问题。

Great progress has been made by taking the following technical improvement for the 2500 ton Hydropress: to replace thin oil with lithium grease in its lubricating system; to add four manual grease pumps; to lubricate the four griding parts of the movable beam and the six parts of the column plug sleeves.

通过对2500吨水压机润滑系统改稀油润滑为锂基润滑脂润滑，加装四台手动干油泵，对活动梁四个导向部位和主柱塞压套六个部位实施油膜润滑的技改实践，使1995年较1994年设备完好率提高1。

It points out the necessity of tubing anchor in pumping well s,especially in deep wells.

定量分析了抽油机井油管自由悬挂可能造成的危害：降低泵效；油管柱振动加速了油管的疲劳破坏；油管屈曲造成套管、油管、抽油杆柱之间的多重磨损。

My manufacture method: Uses half bread flour to add the half mixed grain flours first (for example maize meal, broom corn millet sub-powder, sorghum powder, to be possible), mixes symmetrically, with the boiling hot boiling water synthesis pasta, and the little honey mixes with half two oils; Makes the stuffing, with the little surface, the brown sugar, the walnut not be broken, the candied and preserved fruit broken and the Dried scallop; Then the package becomes the steamed stuffed bun and light pressure Flat (best presses Discus style in order to artistic); Puts in the warm wok with cooking oil to fry in oil Sallow, a good food then completed.

我的制作方法：先用一半面粉加一半杂粮粉(如玉米粉、糜子粉、高粱粉、均可)，掺和匀称，用滚烫的开水合成面团，用半两油及少许蜂蜜掺和；做馅，用少许面、红糖、核桃碎、果脯碎及瑶柱；然后包成包子并轻压成扁状（最好压成铁饼状以求美观）；放入温油锅油炸到焦黄，一个美食便完成了。

Die Casting Machine Supplies: plunger head, cylinder, piston oil spray, and so on.

压铸机的耗材：柱塞头，料管，柱塞油，喷雾剂等。

In order to design the rod string and analyze failure mechanism, the dynamics analysis on rod string of surface driving screw pump must be conducted.

地面驱动螺杆泵抽油杆柱动力学分析是杆柱设计、失效机理分析的关键技术。

Applying Visual Basic ,the paper make modes of buckling ,load calculating, rod designing , sinker bar and couplings designing to realize on computer. It provides effective means for analyzing sucker rod dynamic behavior and designing rod combination in casing production well.

利用VB把建立的屈曲分析、载荷计算、杆柱设计、加重杆和扶正器设计模型编制程序实现计算机计算，为套管采油井抽油杆柱的力学行为分析和设计提供有力工具。

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。
