Our experiment aim at use the acupuncture method"Wang's Jiaji points"which created by the famous doctor Leting wang from Beijing hospital of TCM at the early days of the stroke patients to prevent and treat hypermyotonia,prevent muscle spasm or lessen the spasm level,to improve the stroke patient's ADL.that study is a prospective , randomized, double-blind,parallel-group,use the random digits table method,and compared with the"twelve points of hands and feet",which used frequently at acupuncture department of Beijing hospital of TCM.we use the NIHSS scale, improved Ashworth scale,domestic Fugl-Meyer scale, castigatory MBI scale to score the patients'muscular tension and motor function improvement condition.

本试验旨在在中风病人患病早期应用北京中医院名老中医王乐亭先生的&王氏夹脊穴&预防性治疗肌张力增高，防止肌痉挛的出现或减轻其痉挛程度，以改善中风患者的生活质量。在试验设计方面以北京中医院针灸科目前治疗中风应用较多的&手足十二针&为对照治疗方法采用随机、单盲、平行对照设计。并应用NIHSS、改良的Ashworth量表、国内简化的Fugl-Meyer运动评分法、修订的巴氏指数评分方法对患者治疗前后进行评分以了解患者肌张力增高情况及运动功能改善情况。

"We found there was a significant association between stroke risk and the density of fast-food restaurants," says Morgenstern, who presented the results yesterday at the American Stroke Association's International Stroke Conference in San Diego, Calif.

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。
