查询词典 piston

The working substance could be put in contact with either a boiler, a cold reservoir, or a piston (to which the working body could do work by pushing on it).

工作内容可以提出任何接触锅炉，冷储，或活塞（该工作机构可以做的工作推它）。

The puston attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.

连接竿的底部被附上到机桥。

Lower pairs include revolute or pin connections—for example, a shaft in a bearing or the wrist pin joining a piston and connecting rod. Both elements joined by the pin may be considered to have the same motion at the pin center if clearance is neglected .

低副包括外卷或销钉连接——如在轴承内的或对接活塞或连杆的活塞销的轴，如果不考虑空隙的话，由销钉对接的两种部件都可以被认为在销钉中心具有同样的运动。

The piston is now forced down, the burned gases expanding approximately adiabatically.

这时点燃的气体作近似的绝热膨胀而向下推动活塞。

Reciprocating means up and down or banck and forth, It is the up and down action of a piston in the cylinder blick, or engine block.

大多数汽车的发动机是内燃机，往复四冲程汽油机，但是也有使用其它类型的发动机，包括柴油机，转子发动机，二冲程发动机和分程燃烧发动机。

Mr Ewbank says:"A butment BB slides backwards and forward in a stuffing box and is so arranged (by a cam or some other contrivance connected to the axle of the small cylinder on the outside of the case) that it can be pushed into the interior as in the figure, and at the proper time be drawn back to afford passage of the piston" Bramah and Dickenson adopted this configuration in 1790 as steam engine and also a pump.

ewbank先生说：&一butment BB心跳幻灯片向后和向前迈进一填料框和是这样安排的（由一个凸轮或其他一些contrivance连接到轴的小圆柱对外面的情况），它可以推进到由于在内部的数字，并在适当时机，订定回负担通过活塞& bramah和狄金森通过此配置在1790年作为蒸汽机，也是泵。

The company take excellent equipments as the backing;take the employee of the high caracter as the foundation;Carry out the ISO9001:2000 quantity management systems strictly wit the modern production control mode;Become having the business enterprise of the competition ability more in the local piston wreath profession.

本公司是生产销售汽车、摩托车、农机和通用机械活塞环系列的专业企业，公司以精良设备的后盾，以现代化家产管理模式严格执行ISO9001：2000质量管理体系，以高素质、高技术的员工为基础，成为国内活塞环行业中较有竞争力的企业。

Its operating principle is that electric energy is changed into mechanical energy by drive unit, then the liquid in the cylinder body forms high and low pressure to drive piston up by impeller circumrotation, so vertical motion is changed into wagging of brake arm by leverage and declutch is completed. This product has passed the experiment test by National Quality Supervise Administration and every technical criterion is accorded with national trade standard.

电力液压块式制动器包括电力液压推动器和块式制动架两部分组成，其工作原理是通过驱动装置的电能变成机械能，通过叶轮旋转，使缸体内液形成高低压腔推动活塞向上运动，从而通过杠杆机构将垂直运动转变成制动臂的左右摆动、完成松闸。

The small end of connecting rod acts to-and-fro movement, and the big end of acts circumvolve movement. The connecting rod body acts complex plane movement. The connecting rod is one of the accessories that endures heavy load. And at the same time it endures gas pressure transmitted from the piston, the to-and-fro inertia force and inertia force engendered when itself swings.

连杆工作的小端作往复运动，大端作旋转运动，杆身做复杂的平面运动，连杆是承受负荷最严重的零件之一，同时承受着活塞传来的气体压力、往复惯性力和它本身摆动时所产生的惯性力的作用，这些力的大小和方向周期性变化，易引起连杆疲劳破坏。

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。
