The catalytic activity of three different types of Cu 2+ exchanged zeolites (Cu ZSM 5, Cu Y, Cu M) for the NO direct decomposition, especially the effects of the preparation and reaction conditions on the catalytic activity have been studied.

NO在铜离子交换型沸石上的催化分解＊韩一帆汪仁（华东理工大学工业催化研究所，上海200237）关键词一氧化氮，催化分解，铜离子交换型沸石随着工业生产的发展和机动车辆的增加，向大气中排放的含氮氧化物的量日益增多。

The incise technology of robot is one of the very important research fields of incise technology, but the most of incise robots in use at present are offline show-teaching types, it is not easy to implement real-time tracking for incise accurately.

机器视觉主要用于机器人的轨迹跟踪问题研究、自制车辆的导航、自动焊接和自动切割设备的跟踪。把机器视觉引入切割机的控制过程，可以提高切割机的智能化和高技术含量。

The creep is a main reason, and the rustiness of the prestressed steel is another reason, and more the run of the overrun vehicle.

这里既有混凝土徐变的因素，也有后期预应力钢材的锈蚀、预拱度设置偏差和施工误差的因素，更有超限车辆的行驶等的因素。

The vehicle's precise balance of practicality, catchiness and pricetag make it the ideal service car, or the perfect solution for boxy vehicle lovers.

车辆的精确平衡的实用性， catchiness和pricetag使它成为理想的服务车，或完美的解决方案，为boxy汽车爱好者的天堂。

A new and convenient three-dimensions garage control node design method was achieved by using LON control module to solve the problem of the vehicle s access control in the masterless distributed system.

为了解决在这种无主的分布式系统中对车辆的存取控制，使用LON控制模块实现了一种新的、方便的立体车库智能控制节点的设计方法。

It also introduced selecting methods of the power redirectors in the steering-system design. Moreover it also did the further research on the power redirectors matching and coordination problem of the suspension system and the steering-system, calculated steering wheel strength and momental gradient when the heavy-duty vehicle matched two kind of power redirectors, did entire vehicle performance simulation research on two matching schemes of the suspension system and the steering-system.

还介绍了在转向系统的设计过程中动力转向器的选型方法，另外还针对动力转向器匹配及转向系统与悬架系统匹配问题做了进一步的研究，对重型汽车匹配两种动力转向器时车辆的转向盘力和力矩梯度进行了计算，并对两种转向系统、悬架系统匹配方案进行了整车性能的仿真研究。

To analyze the dynamic performance of hydraulic hybrid vehicles and to optimize the main design parameters of the hydraulic system, the mathematical models of the hydraulic system are established, which includes bidirectional variable-displacement motor, hydraulic accumulator and other components. The relation between polytropic exponent of bladder accumulator and variation rate of gas volume is defined.

为了分析液驱混合动力车辆的动态特性并优化液压系统的主要设计参数，建立了液压系统双向变量马达、液压蓄能器及其它主要元件的数学模型，定义了气囊式液压蓄能器的多变指数和气体体积变化率之间的关系。

A critical component in the assessment of the water quality benefits of PFC is whether the relatively low pollutant concentrations observed in this study are a function of removal of pollutants within the pavement, reduced generation of pollutants through reduction in washoff from vehicles, or the lack of accumulation of pollutants on the new road surface.

一个重要组成部分利益的PFC在水质量评估是否相对低污染物浓度在本研究是观察车辆的，缺少或在washoff从功能，通过减少污染物产生的污染物的去除在人行道上，减少污染物积聚在新的路面。

But, what type of decisions are we making to best take care of this vehicular work of beauty that is carrying us to the next world as long as we are able to hang out in it?

但是，什么样的决定是我们做出的最好的照顾，这车辆的工作，美容，即进行我们未来的世界，只要我们能够把坑列吗？

Most truck power take offs are arranged so that the vehicle's clutch disengages not only the main transmission's output shaft to the drive wheels, but also disengages the PTO.

大多数卡车权力采取平衡的安排，使车辆的离合器分离不仅主传动的输出轴的驱动车轮，而且还脱离接触的动力输出。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
