The simulation shows that the major impact factor on storm surge is the change of the area due to reclamation. The factor of elevated topography due to reclamation is minor. After the reclamation, the extreme high level of storm surge is increased by 1.85~0.09m, decreasing from tail to mouth in Hangzhou Bay. After the planned reclamation, storm surge increases as a whole. The increased peak value is 0.25m at the center of Hangzhou Bay.

结果表明,围涂引起的平面边界改变是影响杭州湾风暴潮的主要因素,围涂引起的地形抬升的影响是次要因素;已有围涂使杭州湾极端风暴高潮位抬升1.85~0.09m,抬升幅度由湾顶向湾口递减;规划围涂后,杭州湾风暴高潮位总体抬升,抬升值最大的湾中部为0.25m。

Especially, the number of type Ⅰ complex terminals which come from unmyelinated afferent fibers recovered to the level of unoperated side. It indicates that morphine may promote the collateral sprouting and synaptic reinnervation of primary afferent fiber, unmyelinated afferent in particular. 4. Although the collateral sprouting and synaptic reinnervation were shown also in spinal cord of operated side in 34 days spared root rats, they were slower than that of morphine spared root group.

表明吗啡促进了备用根初级传入纤维,特别是无髓纤维更快地向L〓脊髓段侧支出芽,稍后在L〓平面脊髓内侧支出芽以及突触重建。4、34天备用根大鼠术侧脊髓内也有侧支出芽和突触重建,不过侧支出芽的速度要比吗啡组慢。5、电镜定量结果也显示,吗啡备用根大鼠和备用根大鼠术侧备用根的无髓纤维数比备用根大鼠非手术侧的分别增多60%和42%。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

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。
