Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。

But if avoidance was impossible, such as in the section cutting through the Hohxil, Qumar and Soga nature reserves, the planners would compare several designs, and put forward protection measures to minimize disturbance to the nature reserves.

对于无法避让，必须经过野生动物活动区域的路段，如穿过可可西里、楚玛尔河、索加等自然保护区的线路区段，在设计中进行了多方案比选，研究提出工程保护对策，尽量减少对自然保护区的干扰。

Finally, all of the data examined here are correlational and, thus, are unable to support strong causal conclusions.

最后，所有的数据，研究这里有相关性，从而无法支持强有力的因果关系的结论。

Especially with the developments of wideband wireless access technology like WiMAX, HSDPA technology could not satisfy the requirements of more broadband bandwidth and high video streaming service in the future. It is coming for 2008 Olympic Games, how to mend their pace to research new technology for 3GPP to get more competitive advantages for futural 10 years?

尤其是伴随WiMAX等宽带无线接入技术的不断发展与成熟，HSDPA技术无法满足未来更高带宽、高视频流等多媒体业务的需求。2008奥运会逐日临近，3GPP组织如何加快步伐研究新系统以满足未来10年内的竞争优势呢？
