因此，研究聚驱抽油机井产出液对抽油杆柱振动特性的影响，对于指导扶正器配置间距设计、完善聚驱抽油机井动态参数仿真与运行优化技术都具有重要的理论和实际意义。

An inside conical surface at the lower end of the joint is designed to ensure the shaft swing freely within an angle range of 10°, thereby the axial bending stress caused by the deflection of the borehole can be eliminated effectively.

这种装置采用类似球形关节的旋转机构，消除了抽油杆柱上下往复运动产生的倒扣扭矩；在短节下端设计有10°的内圆锥表面，使转轴能够在10°范围内自由转动，从而有效地消除了由于井身弯曲而产生的轴向弯曲应力。

In addition, fresh fish around the islands week, as early as the Song Dynasty, Chant Chug State in the show,"Fu Qinghai County," wrote :"perch crisp, soft-shelled fertilizers, Lo-chin, delete columns, oysters, shrimp Quebec, and hopes Chaos, Zhang Jug, sturgeon with cream and umbilical corporations, partners and condensate oil Cypriot belly ..."Thus, here the seafood high scores.

此外，鲜活的鱼虾环绕岛周，早在宋代，邑人储国秀在《宁海县赋》中写道："鲈脆、鳖肥、螺珍、珧柱、牡蛎、虾魁、望潮、章巨，鲟含膏而团脐，鰶凝油而塞肚……"可见，这里的海鲜不下数十种。

By using this method, it can evaluate the displacement and the load of any section at any time.

运用此方法，能计算出抽油杆柱在任意时刻，任意截面的位移和载荷。

And Jacob set up a pillar in the place where He had spoken with him, a pillar of stone; and he poured out a drink offering on it and poured oil on it.

35：14 雅各便在神与他说话的地方立了一根石柱，在柱上浇了奠祭，并且浇上油。

The flam e hot spraying can outstandingly increases service life of plunger in sucker rod pump.

在抽油 泵柱塞表面实施喷涂工艺，可显著地提高其使用寿命。

This article analyzes systematically the work process of fuel injection system in detail. It analyzes the fault fundamentals and its influence of three coupling parts in the high pressure oil road and the injection process, three coupling parts include plunger coupling parts, delivery valve coupling parts and needle valve coupling parts. It discusses the pulse situation of fuel pressure under the every kind of typical fault model, and regarding this as according to pick up the pulse signal of pressure from the high pressure pipeline, and process wavelet decomposition, picks up the of parameter fault, make use of the model identification technique, realizes to the intelligent diagnosis of fuel injection system fault.

文中系统地分析了燃油系统的工作过程，对高压油路中三偶件(柱塞偶件、出油阀偶件、针阀偶件)、喷油过程等的故障机理及其影响进行了分析，讨论了各种典型故障状态下的燃油压力波动情况，并以此为根据，从高压油管处提取压力波动信号，提取故障参数，利用模式识别技术，实现了对燃油系统故障的智能化诊断。

I am the Secretary's main operating piston, filler letter, the first oil pump, plunger, bush, into the exhaust valve, piston rings, seal ring, O-ring, oil scraper ring, and a variety of sub-oil machine, by pressure, etc. and run all types of second-hand spare parts.

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.
