降低速度

It baffles me that President Bush would rather go to Saudi Arabia twice in four months and beg the Saudi king for an oil price break than ask the American people to drive 55 miles an hour, buy more fuel-efficient cars or accept a carbon taxor gasoline tax that might actually help free us from what he called our "addiction to oil."

一直令我困惑不解的是布什总统宁可在四个月中两度造访沙特阿拉伯，乞求沙特国王降低石油价格，也不愿意敦促美国民众以时速55英里的速度驾车，购买更多节油轿车，接受烟尘排放税或汽油税，而这些举措或许真的可以帮助我们从被布什总统称之为&对石油的嗜好&中解脱出来。

An optical packet exchanger is provided which, in a situation where a transmission path for an optical packet is to be switched by using an address signal, prevents the transmittable capacity for the information signal from being decreased, and which facilitates the extraction of the address signal even if the modulation speed for the information signal becomes high.

提供了一光分组交换器，在一种情况下通过使用一地址信号来交换光分组的传输路径，防止信息信号的可发送容量降低，并且即使在信息信号的调制速度变高时，也便于提取地址信号。

The switching power amplifier is optimized based on the achievement of electromagnetic force, and the circuit structure of tristate power amplifier with soft-switching is designed. This circuit owns the advantages of reducing the dissipationpower on the power component and improving the speed of system dynamic response, enhancing the stability of the electromagnetic force in the final state, and the nice result is presented by the simulation. The small-signal model of the power amplifier is also established.

在实现支撑所需的电磁力基础上，对开关功率放大器电路进行了优化设计，采用三电平软开关的电路结构，以降低主功率器件的功耗、提高系统的动态响应速度、提高稳态电磁力的平稳性；仿真分析表明可以达到预期的效果；最后还建立了功率放大器的小信号模型，为控制系统的调节器设计提供了依据。

Results show this new-inlet hydrocyclone has original sides on liquid spin-making and stabilize its flow field. Moreover this gradual contraction inlet may translate some pressure energy of liquid into kinetic energy and increase circumrotate speed. These play active actions on improving separation efficiency. Moreover, the uniflow hydrocyclone has the traits of big capacity, low pressure drop and a little low separation efficiency in contrast to the returned flow hydrocyclone. This hydrocyclone system has the higher separation property in contrast to the single-level hydrocyclone.

实验结果表明：这种新型入口结构水力旋流器在流体的导旋方面具有独到之处，能很好的形成稳定的流场；同时这种渐缩式入口方式，可将来液的一部分压能逐渐转化为动能，提高了旋流速度，对提高分离效率起到积极作用；采用新型入口的直流式水力旋流器比返流式水力旋流器压降低，处理量大且分离效率略低；组成返流式水力旋流器串联系统相对于单级水力旋流器具有更高的分离性能。

Analysis of vertebroar terial blood flow has shown that in cases with pathological conditions the compl iance of the vertebral artery and peak systolic veolicity and capacity are signi ficantly decreased Conclusions:The Segmented K-space cin e phase-contrast MR is an important tool for non-invasive evaluation of vertebroarterial blood flow.

血流分析表明在病理情况下椎动脉的顺应性低于正常组，峰收缩期流速和平均流速明显降低，返流均百分比增加。结论：MR相位速度图对椎动脉的血流动力学研究具有重要意义，对椎动脉型颈椎病可提供可靠的诊断依据。

The paper has studyed the characteristics of seismic wave field in the media of EDA, and has made out three aspects of numerical simulation on wave field features by using definite difference: The simulation of P-wave ground seismic logs in the media of EDA; the diagnostic complication of seismic wave field in cranny belts due to the scattering of cranny wrappage; the decreasing of amplitude and the reversing of polarity of the wave reflected on not only the top but also the bottom of fracture zone.

2通过罗67井岩芯的系统研究表明，泥岩的横波和纵波速度随温度增大而降低，一定温度条件下随为压力而增大；泥岩裂缝的测井曲线一般表现为高电阻率、负自然电位异常、低声波时差，利用该规律可以半量定地识别划分泥岩裂缝储层特征，为解决不同度数据的相互匹配这一重点和难点问题提供了思路和方法。
