货车

This is the only air-conditioned van we will have and it is going to be very helpful to us.

很感谢你们赠送的货车，这是我们唯一有冷气的货车，这对我们会很有帮助的。

It is shown from the results that the acting force and vibrating acceleration are increased due to its axle load, however, the dynamics interaction between 25 t load wagon and the turnout can be improved by the rubber stack in its axle box, especially in the index such as derailment coefficient, reduction rate of wheel load, opening size of tongue rail and point rail, which is almost equal to the dynamics of 21 t axle load wagon.

结果表明尽管轮轨力和振动加速度因轴重增加而相应增大，但由于25t轴重货车在轴箱处采用橡胶堆，使它与道岔之间的动态相互作用有所改善，尤其是脱轨系数、减载率、尖轨和心轨前端开口量等指标上，与21t轴重货车引起的系统振动值基本一致。

The truck cast steel three big piece type bogie is easy to maintain. But since the grate weight under spring and the large operation strength during running, it is difficult for the bogie to keep the positive position. The critical speed of the snaking motion is low, which is inapplicable for high speed running. The other type of truck bogie is H type integrative truss. Its structure is complicate relatively, which is not easy to manufacture and maintain. But it can keep the positive position of the bogie preferably. And because it is adopted the structure of axle box one series elastic suspend, the weight under spring reduces. Which achieve the effective control to wheel sets and improve the running quality of the bogie distinctly.

货车铸钢三大件式转向架便于制造维修，但因其簧下质量大，在运行中轮轨作用力大，转向架难以保持正位，蛇行运动临界速度低，不适用于高速运行；货车转向架的另一种形式是"H"型构架一体式，结构较为复杂，不便于制造和检修，但它能够较好地保持转向架的正位，而且由于采用了轴箱一系弹性悬挂结构，降低了簧下质量，实现了对轮对的有效控制，明显地改善了转向架的运行品质。

According to the wheel-axle production line project of Ji" nan locomotive and rolling stock plant, this dissertation put forward "Designing of wheel-axle foundation production line and management of wheel-axle information and mainly carried on following several aspect works: According to current new technique of the domestic and international wheel-axle assembling is researched, and combining present produce condition, we have designed the machining and assembling product line of axle and wheel and non axle box rolling bearing assembling product line.

根据济南机车车辆厂轮轴工艺线建设项目，本文提出了"货车轮轴基础工艺线设计及轮轴信息化管理"研究课题，并主要进行了以下几方面工作：通过对目前国内外轮轴加工组装的新技术新工艺进行研究，结合工厂轮轴生产现状，对货车轮轴生产线进行了工艺方案设计。

The evolution process of freight car coupler s in our country in the recent 50 years is reviewed.

回顾了我国货车车钩50年来的演变过程，分析了其现状，并通过与美国货车车钩的比较，展望了我国货车车钩的发展趋势。

Consequently, the development of the vehicle life management is, among the means for guarantee of the safety of railage, among the methods for guarantee of the whole technical estate of vehicle, among the primary contents for the implement of maintenance reform on vehicle.

因此，对货车及其关键零部件实施寿命管理，是保证铁路运输安全的重要手段之一，是保证运用货车整体技术状态稳定的措施之一，是货车实施维修改革的主要内容之一。

From the definition of goods train turnaround time, we can know if we reduced turnaround time, accelerated the turnover of vehicles,especially serious lack of empty train, we can effectively control turnaround time and improve transport efficiency, whth important practical significance, especially present situation, the national railway can do more transport task with same number of vehicles, increasing transportation revenues and the local railway will redue occupancy costs of country rail to reduce costs and improve efficiency.

由货车周转时间的定义即可得知，如果能够成功压缩货车周转时间，加快车辆周转，尤其在全路空车严重不足时，则可以有效控制货车周转时间、提高货车车辆运用效率，这具有十分重要的现实意义。更何况在当前新形势下，加速货车周转，对于国铁即意味着能以同样数量的货车完成更多的运输任务，进而增加运输收入；对于地方铁路或专用铁路则意味着将大大减少对国铁货车占用费的支出从而降低成本、提高效率。

Wagon body is a complicated weld structure. While physical wagon can not used to do fatigue test, how to make anti-fatigue design has been discussed in this paper. One coal hopper wagon has been taken as an example to study about anti-fatigue design of the wagon. First of all, based on finite element technique and the theory about how to predict fatigue life of weld structure, the technology route and key technique are given as well, which is based on AAR standard about weld structure wagon fatigue life predicted.

论文认为货车车体是复杂的焊接结构，为了使货车车体焊接结构抗疲劳设计在产品的图纸上就能卓有成效地展开，论文以新型煤炭漏斗车为研究对象，对煤炭漏斗车车体抗疲劳设计开展了一系列研究：首先，基于有限元算法和焊接结构寿命预测的疲劳理论，给出了基于北美铁路协会AAR标准的货车车体焊接结构寿命预测的技术路线及关键技术。

According to the driver's momery, the goods were sold out very early. On the way back that passing by Miluo,Hunan, a taxi at high speed ran in the truck's face. In order to give way to the taxi, the truck crashed with a truck that aside it and then hit on the house that along the road. The hirers were sleeping in the truck at that time. The truck was badly stricken and all the glass was broken into pieces, the head of it was badly damaged, the front tyre was broken away from the truck!

当时货车上有司机和另外3名租主，据司机回忆，那天货主的货物很早就卖完了，在回家的路上，经过湖南汨罗的时候，路上有一辆高速行驶的的士迎面而来，司机为了让的士，与车旁的一个货车相撞，相撞后又撞到路边的房屋上，当时租主们都在车内睡觉，货车受到严重的撞击，车上的玻璃全部破碎，车头严重受损，货车的前轮彻底脱离！

Company Qiyun Department has developed, Qiyun edge lines as:- Qingdao, Guangzhou, Guangzhou ---- Beijing, Guangzhou ----- Shanghai, Qingdao of motor transport more than 70 large trucks, the Beijing-Qiyun VOLVO has 20 box-type truck, the Shanghai line has 30 motor transport truck.

公司汽运部已发展成熟，汽运优势线路为：广州---青岛、广州----北京、广州-----上海，青岛线汽车运输有70多辆大货车，北京线汽运有20辆VOLVO箱式大货车，上海线汽车运输有30辆大货车。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
