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.

Results show that MoS2-Ti composite coatings grow in islands pattern, their cross-section appear to be dense columnar structure.

结果表明：不同Ti含量的MoS2-Ti复合薄膜呈岛状生长模式，断面呈致密细柱状，结晶状态均为无定形态；薄膜的显微硬度随Ti含量增加而升高；MoS2-Ti复合薄膜在大气中的摩擦磨损性能优于MoS2薄膜，掺杂适当Ti可以使MoS2-Ti复合薄膜的摩擦曲线波动减小，耐磨寿命提高，在本试验研究范围内，含30%Ti复合薄膜的耐磨寿命最长，当Ti掺杂量达到50%时MoS2-Ti复合薄膜失去润滑性能。

08 Ns using deconvolution from the combination of the phase plane method and iterative convolution method.

通过相平面法和迭代卷积法相结合的解卷积处理，测得乙醛40％水溶液的真实荧光寿命为（7.25±0.08）ns，表明这是一种采用纳秒量级的仪器测量纳秒甚至亚纳秒荧光寿命的有效方法

In order to maintain relable action and long service life, please avoid theoccasion beyond the stipulated ambient temperature.Do not drench it with water or water-soluble cutting lubricant when it is usedwith cover,althouth theproximity sensor is waterproof.

为保护动作的可靠和寿命长，请避免有关规定以外的温度外界条件下，接近传感器虽为耐水结构，若装上罩使用，勿使水和水容性切削油等淋到，则可更好地提高可靠性及寿命。

The one that need to emphasize is, advanced science and technology brings the extension of people's life-span, if beneficiary that the life-span lengthens' thinking stops but can only be looked after, Then even his unwilling death society will execute the bill of euthanasia , Old people's existence can't deprive children's existence .

需要强调的是，高技术带来人寿命的延长，倘若寿命延长之受益人思维停顿而只能受照顾，那么即使他不愿死亡社会也将强制执行安乐死的法案，老年人的生存不能剥夺儿童的生存。

In order to improve the life of cement concrete bridge deck pavement,compound beam test was used to research the fatigue characteristics of hot mixed asphalt courses on bridge deck,finite element analysis method was employed to make the mechanical response of compound beam accord with that of actual bridge deck under the same load,the fatigue test was done for compound beams with different pavement structures.

为了提高水泥混凝土桥面沥青混凝土铺装的使用寿命，以复合梁试验评价不同的桥面沥青铺装结构的疲劳性能，采用有限元法分析荷载作用下复合梁试件具有与实际梁体一致的应力响应，并采用复合梁疲劳试验测试不同桥面沥青铺装层组合的疲劳寿命。

Distribution of contact stress and contact status of dovetail joint are obtained,and the location of fretting fatigue crack predicted.

进一步应用该位置处的应力场和接触状态进行结构的寿命预测，通过燕尾榫连接结构的低周微动疲劳试验，获得了寿命预测模型中的相关参数。

The rebounding damping technology, that the function in the same kinds of products sold in the market are not in common, means when you pull the drawer out to the bottom, it will has a process of soft closing and rebound, which can reduce the noise made by the things loaded in the drawer in efficiency. Moreover, because of the variable damping technology, which help to lessen the force of of the inertia made by the motion of the box when open or close it, and it will extend the useful life of the cabinet effectively. Therefore, it proved that the two-way slow motion cabinet have a longer useful life than the single soft-closing drawer system. And that is the reason why GRASS HOPPER is so popular in many countries all over the world.

反弹阻尼技术就是当你的橱柜抽屉拉到尽头时，有一个轻微的缓冲反弹过程，这样就减小了抽屉里面的装载物的碰撞声音，能达到更加实际意义上的静音，同时由于具备这种功能，在开合抽屉时就大大减小了由于抽屉的运动惯性对柜体产生的破坏力，这样就有效的延长了橱柜的使用寿命；所以使用双缓冲抽屉的橱柜比使用单缓冲抽屉的橱柜寿命明显延长，而市场上还没有具备这种功能的同类产品。
