The impoved design of the D35 trailor-form is rational, since the wagon ear is connected with the heavy load by hingel joint instead of spherical articulate, and the lateral relative displacement of safety pins is very small due to the rolling stiffness of schnabel grider, so that the friction stability of spherical-surface sockets of press-down cylinders is guaranteed.

新型D35联挂改进设计是合理的，因为车耳球铰改为车耳铰销联结后，利用钳夹梁的侧扭刚度来减小安全销相对横向位移，进而保障压柱油缸球面座的摩擦稳定性。

After the ultra-clean micro-sized coal water slurry combusts in the diesel engine, the Plunger Couple jam often happens.

精细水煤浆在柴油机上燃烧一段时间后，油浆泵柱塞偶件经常出现卡死现象。

The plunger stroke loss factor, pump barrel fill coefficient, leakage coefficient and bulk effect coefficient of produced liquid.

有杆抽油系统中抽油泵容积效率的计算一般由柱塞行程损失系数、泵筒的充满系数、漏失系数和抽汲液体的体积效应系数等 4部分构成。

By using elastic stability theory and in combination with field work, a method in calculating space when installing sucker rod lifter is worked out and an example is provided.

运用纵横弯曲梁及弹性稳定理论，结合工程实际，分析得出了在全井各种井段合理安装抽油杆柱扶正器间距的计算方法，并给出了计算实例。

The naphthenic acids in 200~430℃ distillate of Liaohe crude oil were separated by column chromatogram and anion exchange resin.

采用柱色谱和阴离子交换树脂法分离出辽河200~430℃馏分油中的环烷酸。

Pure methyl esters were prepared using common oil plant seeds and the fatty acid composition of the achieved oil was measured by capillary column chromatography.The kinds and dosage of reagents for fast preparation of the methyl esters were investigated and the chromatographic conditions using two kinds of capillary columns were optimized.

本研究通过参考文献，直接使用常见油料植物种子制备纯油甲酯进行分析，探讨了快速制备甲酯的试剂选择及用量，强极性和弱极性的两种不同类型毛细管柱的最佳色谱分析条件，并将测定的主要脂肪酸含量与国家标准进行比较，结果较为一致，而且平行测定的相对标准偏差表明方法有较好的精密度和重复性。

Among them, the glue solvent addition-nitric acid had a greater impact, and its amount was controled at 8%~10% for the best; 2though the result of the ball catalyst prepared by oil ammonia column was better, the process was more complex; 3performance of the catalyst prepared by impregnation ball support was poor.

其中，胶溶剂硝酸的加入量有较大影响，其用量控制在8%～10%为最佳；2油氨柱滴球成型法制得的球形催化剂虽然齐聚反应效果较好，但工序较复杂；3浸渍球形载(来源：A61BcacaC论文网www.abclunwen.com)体法制得的催化剂催化性能较差。

According to the conditions under the oil well and the technical requirements,the pump structure is changed from the plunger form to the piston form to compensate the wear in running of the piston ring by elasticity of itself.

活塞式抽油泵是目前普遍采用的采油设备，由于泵筒发生不同程度的磨损，导致在抽油过程中出现泄漏，根据油田井下的工况和技术要求，在不改变泵筒的前提下，把柱塞式结构改成活塞式结构，靠活塞环自身的弹性力来补偿工作运行中的磨损，所研制的活塞环，经油田的实际应用，收到良好的应用效果

Auto parts: Fuel injection system valve follower, plunger piston and fuel injection needle, etc.

Our company specializes in production of fuel injection precision coupling products .including nozzle, plunger, delivery valve, pump head, repair packs and so on.

我公司专业生产燃油喷射精密偶件，产品包括喷油嘴、柱塞、出油阀、泵头、修理包等。

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。
