The other bonus that the C200K enjoying is its steering department. It is different from most European cars that there would be sufficient road information feedback to the driver. The driver can make a good judgment on how he wants to drive the car. Just 2.7 turns lock to lock and 10.8 meters of turning circle; this setting reveals the enormous effort in making the C-class as an enjoyable car to drive but at the same time with a lot of luxurious appointments. Obviously, the C-class has evolved from just an expensive sedan into something representing the come back of the oldest car making in the world.

另一个C系的优点是它的转向部门，它与其他欧洲汽车是它有足够的道路资讯以以传递予驾驶者，因而，驾驶者可以因而作出合适的判断以协助它的驾驶需要，它的回转只是2.7手軚，10.8公呎的回转直径，因而，可以令C系成为一辆可以令驾驶者享受的豪华驾驶工具，明显地，C系脱离了只是名贵的汽车称号，而它的娇人成绩使平治-世上最资深的汽车公司可再次获得殿堂级的显赫地位。

The OLEDs(organic light-emitting devices) have been attracting more and more attention as an important flat display technology, because they have advantages, such as self-luminescence, low operation voltage, high luminance and efficiency, broad viewing angle, short response time, etc.

The researches show that the results obtained by using adjointoperator method are same with the results obtained by using matrix representationmethod.Two methods have respectively the self-advantage.

所得结果说明利用共轭算子法得到的结果与利用矩阵表示法得到的结果完全一致，两种方法各有其优点。

They are particularly very promising energy storage systems to replace traditional secondary batteries for space application since URFCs have distinctive advantages over secondary batteries in that they are long-term energy storage systems with extreme high specific energy and without permanent losses by self discharge and capacity limit.

一体式可再生燃料电池是可再生燃料电池中最先进的一种，它是在同一组件上既可以实现燃料电池功能又可以实现水电解功能的储能和供电系统，具有能量密度高、使用寿命长、使用中无自放电且无放电深度及电池容量的限制等优点，是极有希望在空间、军事及可移动电源领域替代传统二次电池的储能系统。

Most of the developing X-Y tables applied Ball screw-driven table system or piezo-ceramic linear motor by taking the advantages of carrying heavy loads. However, their cost are very high in contrast to the proposed architecture. In some particular application fields. Carrying heavy loads is not the main requirement for the X-Y table, such as organic cell inspection, optical fiber alignment, nano-material research, ect. Taking this idea as a premise, if we could able to create a precise positioning X-Y table with very low cost, we will be able to achieve the extremely high commercial value and highly competitive ability.

X-Y精密定位平台的开发，不外乎线性马达或压电陶瓷马达搭配导螺杆或其它机构所组成，其优点是可以承载较重之待测物体，缺点是重量大且价格昂贵，在许多应用上并不要求测试平台拥有太大的荷重能力，如生物医学诊断及检测，生物晶片开发及检测，光纤校准，奈米材料研发，奈米量测及精密全平面扫描等等，如果以此为前提，能以极低之成本创造出高精密定位之X-Y平台，将会有极高之商业价值及极大之竞争力。

The equation which process screw surface with tools of disk conical surfaces was established by using Euler vector principle in the paper,from which we can see that this method has better applicability and validity and the advantages of faster speed.

本文利用欧拉向量原理建立了用盘状锥面刀具加工螺旋面的方程式，从中可以看出这种方法有很好的实用性和有效性，而且具有计算速度快捷的优点。

Therefore, in order to enable the screw to smoke, Pai oil separated from the mouth, the screw thread section of the length of at least larger than a lead.

因此，为了使螺杆能吸、排油口分隔开来，螺杆的螺纹段的长度至少要大于一个导程。从上述工作原理可以看出，螺杆泵有以下优点

Then some improvements which bestow the cavity with certain characteristics are achieved on the basis of the original laser. There are more adjustment factors, such as the detuning of gratings and the length of the cavity. The resonance cavity can make use of each other better, and the synchronization of the dual-wavelength laser can be improved.

然后我们在原有激光器的基础上做了一些改进，改进后的腔具有的优点有：腔的调整因素有所增加，比如镜的失调，腔的长度；同时可以改变两谐振腔的相互利用情况，以便更有利于双频激光的同步运行。

Along with the pros of using a longboard, there are also disadvantages: A longboard is big and heavy, which makes it difficult to paddle out through crashing waves; and it can be quite difficult to maneuver .

使用长板有其优点，当然也伴随著一些缺点︰长板又大又重，所以比较难在大浪中穿梭；要操控方向也相当困难。
