主要零件

Because of the connecting rod is one of dyadic engine of piston and main compression engine part, whose larger end hole and crank shaft link up , the small head hole links up by the wrist pin and the piston , whose effect is that the piston gas pressure is transmitted to the crank shaft , collect crank shaft gas in driving but setting a piston in motion to compress a cylinder. the intensity is high.

因为连杆是活塞式发动机和压缩机的主要零件之一，其大头孔与曲轴连接，小头孔通过活塞销与活塞连接，其作用是将活塞的气体压力传送给曲轴，又收曲轴驱动而带动活塞压缩汽缸中的气体。

Central parts of mechanism of elevating and equilibrating were also processed static, dynamic, flectional analyses with finite element method by using Pro/MECHANICA. In the end, its dynamical model was built and simulated in ADAMS, dynamical responding of its hydraulic elevating part was analyzed, gun muzzles elevation disturbance in different fire angle and so on were obtained, work performance of mechanism of elevating and equilibrating was more studied.

使用Pro／MECHANICA对高平机的主要零件进行了有限元的静态、动态、屈曲等分析；最后在ADAMS中建立高平机动力学模型并进行仿真分析，分析其液压高低机部分在火炮发射时的动力学响应，获得了不同射角下由高平机引起的炮口高低扰动等数值，进一步验证了高平机的工作性能。

And selected homological hydraulic elements, drawned up the assembly pictures and the charts of major parts according to the calculation and flow analysis.

并根据计算及流量分析选取了相应的液压元件，画出了液压缸及整个系统的装配图及主要零件图。

"Each ball bearing has three main parts: two grooved, ringlike races and a number of ball s."

球轴承有三个主要零件，即两个带有沟槽的套圈和许多球。

"Each ball bearing has three main parts: two groove d, ringlike races and a number of balls."

球轴承有三个主要零件，即两个带有沟槽的套圈和许多球。

The Company are the production of forged steel valve series of professional firms, using international standards and national standards, a modern scientific management as the goal, actively introduce advanced technology and equipment, the use of CNC machining to ensure accuracy and interchangeability Products , valve sealing the introduction of automatic welding equipment and high temperature wear-resistant cobalt-base Stellite hard alloy material, the valve can be assured that the main components and quality of physical and chemical properties.

本公司是生产锻钢系列阀门的专业公司，采用国际标准和各国家标准，以现代化科学管理为目标，积极引进国内外先进技术和设备，采用数控机床加工，确保产品精度与互换性，阀门密封采用自动堆焊设备和耐磨高温的司太钴基硬质合金材料，确实保证阀门主要零件的理化性能和质量。

When all parameter calculations are over after, requested the technique requests to the design and assemble of the main spare parts to all carry on analysis to the assemble project that whets to have.

当所有的参数计算完后，对磨具的装配方案，对主要零件的设计和装配要求技术要求都进行了分析。

Use symmetrical cylindrical gear,reduction gear and spiral load brakes to achieve an unique combination of high mechanical efficiency,lower effect on hand chain and brake reliability.

主要零件均采用优质钢材制造，起重链条选用合金钢材，用引进的先进设备制造。

Closed has carried on the reasonable determination highly to the mold, but also designs the mold the major parts to fall the material concave mold, the convex-concave mold, the counter- drawing raised mold, the counter- drawing concave mold, the concave mold dead plate and so on.

对模具的闭合高度进行了合理的确定，还设计出模具的主要零件落料凹模、凸凹模、反拉深凸模、反拉深凹模、凹模固定板等。

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。
