Friction rubber draft gear, as one of high-capacity draft gears, is developed after friction steel spring draft gear. Rubber has energy absorption capability and non-linear rigidity capability, so the friction rubber draft gear's capacity is usually higher than the friction steel spring bumper.

摩擦式橡胶缓冲器是继摩擦式钢簧缓冲器之后开发的一种大容量缓冲器，这种缓冲器利用了橡胶自身具有吸收能量及非线性刚度的特性，因此其容量一般比摩擦式钢弹簧缓冲器高。

And the final standard could be different enough to make Draft N gear outdated in 12 to 18 months.

而最后敲定的标准可能会大不相同，因而 Draft N 技术很有可能在12到18个月后就被淘汰。

In this paper,with the analysis of the metro operating condition the structure and parameters of the draft gear,the causes to rigid impacting are discussed,thus providing evidence to the improvement of designing.

本文通过对地铁运用工况和该缓冲器结构、参数的分析，探讨造成刚性冲击的原因，进而为改进设计提供依据。

The modeling methods about vestibule diaphragm, coupler and draft gear are introduced, too.

模型E和模型F可用于研究列车系统的运动稳定性、运行平稳性及动态曲线通过性能。

The research on draft gears for freight cars in Russia is introduced,especially the characteristics of the resilient rubber draft gear s are described in detail.

介绍俄罗斯货车用缓冲器的研究情况，重点介绍弹性胶泥缓冲器的特性。

The influence rules between the initial pressure,spring stiffness,oblique plane angle,friction coefficient of friction pair,friction force and the characteristics of draft gear were analyzed.

分析了缓冲器的初压力、弹簧刚度、斜面角度、摩擦副间的摩擦因数以及摩擦力对缓冲器工作性能的影响规律。

So far, a larger of rubber draft gear is designed by the superelasticity data attained from people's experiences and some experiments, however, these data have some big differences from the rubber's actual viscoelastic properties.

但现今大部分橡胶缓冲器是根据试验和经验所取得的超弹性值来设计的，相对于橡胶的粘弹性行为，误差较大。

Draft gear is used to reduce the bump between the vehicles when the train runs or shunts, whose form of load is mainly impact load, and as for viscoelastic material such as the rubber, whose stress is not only relate to strain but also relate to the time, so under the action of impact load, the viscoelastic material's capabilities is very different from the common elastic material.

由于缓冲器是用于缓和列车运行及调车作业时车辆之间的冲撞，其所受载荷形式主要是冲击载荷，而对于橡胶这种粘弹性材料来说，由于其应力不仅是应变的函数，还是时间历程的函数，所以在受冲击载荷作用下的特性和普通的弹性材料的特性有很大的不同。

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。
