A new radiator(strengthened tubular and corrugate fin type radiator) was presented in the paper.

1前言冷却系统是内燃机车的重要组成部分，其作用是使机车维持在最佳工作温度。

The formation process of corrugation is the feedback mechanism of vehicle-track coupling dynamics and rail damage mechanism.

波磨的形成过程实际上是一种由车辆—轨道耦合动力学和钢轨破坏机理构成的反馈机制，其中轮／轨关系作为联系机车车辆系统与轨道系统的关键环节，是构成这种机制的重要内容，属于接触问题。

The height of cowcatcher from the top of rail with new wheels and 2/3 variable supplies (adjustable within the range of wheel tread worn): 110+10 mm.

2.30 机车排障器距轨面高度在新轮和2/3整备重量下（在车轮踏面磨耗允许范围内可调）：110＋10 mm

In this paper, the 3D FEM models of cone-tread and worn-tread locomotive and vehicle wheels are firstly established, which come into contact with the rail of standard size. There hasn't been any more refined 3D FEM computation model of wheel/rail up till now. The elastic effect of crosstie and roadbed is also considered.

本文建立了锥形踏面、磨耗形踏面的机车和车辆车轮分别与标准轨道相接触的三维有限元计算模型，模型还考虑了轨枕和部分道床的弹性作用。

First, under general conditions, we solvethe locomotive's cyclic working current equation with the analyticaland the numerical methods combined, giving a computing module quitefitting in with practicl results.

文中首先在一般条件下用解析法和数值方法综合求解了SSI型电力机车的周期工作电流方程，给出了比较切合实际的计算模型。

The complete model of locomotive and vehicle and the exact motion equations of wheel-set are established, in which, three-dimension wheel/rail contact geometry is taken into account and the Kalker's creep theory is employed to analyze the effects of the contact region of wheel/rail. An iterative procedure of solving wheel/rail creep force is proposed to improve the existed calculating method. Finally, the motion equations of vehicle with 23 DOFs are derived using the D'Alembert principle.

建立了较完善的机车车辆分析模型和较精确的轮对运动方程：考虑三维非线性轮轨接触几何关系，用Kalker蠕滑理论研究了轮轨接触区的蠕滑效应，建立了较为详细的轮对运动方程，提出用迭代法来求解轮轨蠕滑力从而对现有蠕滑力求解方法进行了改进，并采用D′Alembert原理推导了23个自由度车辆的运动方程。

In the second place, we discuss the circuit design and implementation of host system and data record system.

其次，本文详细讨论了机车信号记录仪主机系统与数据记录系统的硬件电路的设计和实现。

The paper first demonstrate the feasibility and the significance of the applications of heavy oil in locomotive diesel engine.

本文首先对重柴油在机车柴油机上应用的可行性和意义加以论证。

While GE currently is the world leader in locomotive diesel-electric and electronic control systems technology, China currently is a leader in high-speed rail technology for speeds of 220 miles per hour.

虽然目前是通用电气机车柴油机在世界领先的电气和电子控制系统技术，中国目前是在高速铁路技术为每小时220英里的速度领先。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
