They thought that the great distances from the nearest Soviet railhead insured that the Red Army could never concentrate large armor and infantry forces at Nomonhan.

他们认为即使最近的苏联铁路终端也太遥远了，这限定了红军在诺门坎无法聚集大批装甲和步兵部队。

Rail grinding has become increasingly popular as a means of correcting surface damage to rails,and also controlling wheel contact position and railhead profile.

钢轨打磨作为解决钢轨表面缺陷、控制轮轨接触位置和控制钢轨外形的手段，应用越来越广泛。

From the south, the sixtyfive kilometer road running from the railhead at Handagai to Chiangchunmiao became a bog in late June with the onset of the rainy season.

从南方的铁路终端罕达盖到将军庙的路有65公里，随着六月末雨季的到来，这条路变成了沼泽。

While the four inch railhead profile applied to curved and tangent track did mitigate corrugation development and the noise associated with them , it introduced a new problem : vehicles began hunting after a total of only 400 miles of accumulated traffic .

在曲线段和直线段采用了4英寸的轨头廓形进行打磨以减缓波浪磨耗的发展，并且可以降低噪声，但这带来了一个新问题：车辆仅累计运行了400英里就发生了不正常的摆动。

In this paper, a model forwheel/rail with arbitrary profiles contacting in an arbitrary point is built to calculate contact area and contact surface stresses. Then bytakingthe calculated surface stresses as applied load, the stresses inside the railhead are calculated through the three dimensional elastic-plastic finite element method.

建立了一个任意形状钢轨和车轮在任意点接触时，接触面形状和接触面力的计算模型，然后把计算出的接触面力作为外载施加到三维弹塑性有限元模型中，进行轨头内部应力的计算，从而构成一个完整的计算方法。

Considering the real wheel/rail geometry and boundary condition, the distribution of elastic-plastic stress in the rail-joint, the effect of the inclusion and crack in the rail surface on the distribution of elastic-plastic stress in railhead are analyzed by using software ANSYS.

本文以大型有限元软件ANSYS为分析工具，同时考虑车轮和钢轨真实的几何形状及边界条件，分析了钢轨接头位置弹塑性应力场、钢轨表面点状缺陷和条纹状钢轨表面缺陷对钢轨接触应力场的影响。

To the crack in the rail surface, the effect of longitudinal location on the distribution of the elastic-plastic stress and strain in the railhead is calculated. The maximum stress around the crack in the rail surface over the yield stress and the steel around the crack has plastic strain.

对于条纹状钢轨表面缺陷，主要计算了不同横截面位置条纹状钢轨表面缺陷对轨头内弹塑性应力场和应变场的影响，条纹状钢轨表面缺陷的存在使其周围最大等效应力超过了钢轨材料屈服极限，导致该位置钢轨发生了塑性应变。

The result indicates that the hearing capacity of rails have heen improved highly. The effect of normalizing treatment on railhead and rail bottom angle is more excellent than manually operatinn.

结果分析表明：钢轨接头经数控正火后，静弯承载能力明显提高，轨头和轨底角区域正火效果理想，正火质量优于手动正火。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
