In addition we also make research on the residual curve velocity analysis and find that its application is not good and the efficiency is iow. The reasons is that the hypothesis is rigid and it is a local optimizing method.

本文还对目前实用性较强的剩余曲率速度分析方法进行了研究，指出该类方法的应用效果不佳和效率较低的原因在于，理论假设过多，与叠前深度偏移的初衷相违，同时该类方法是单点速度分析，是一局部优化方法，而无法解决具有强烈横向速度变化以及地下构造倾角较大的地震速度建模问题。

Thirdly, the problems of institution investor'optimal liquidation strategy and optimal liquidation time were investigated with the conditions that the price of risky asset followed arithmetic Brown motion and liquidation velocity was limited. The problems involved the following scenes: price impact function was linear expression of liquidation velocity which was boundary closed set with an isolated point; price impact function was stochastic; price impact function was nonlinear.

接着，当风险资产的价格服从算术布朗运动，且对投资者的变现速度做出限制时，研究机构投资者的最优变现策略和最优变现时间问题，其中包括：价格冲击函数为变现速度的线性函数，变现速度是一带有孤立点的有界闭集；价格冲击是随机形式；价格冲击是变现速度的非线性函数。

The stude announces that their changeable regular of the center of gravity level speed in supporting phase is falling in tne first cushioning phase. When their center of gravity's vertical lines pass their heels and their knee joints go on extended contraction ,their center of gravity level speed has extended .the reason is that their angles have passed the heels and their swinging legs' kenn joints have swinging the front of their bodies. Its power originates the swinging leg's forward active swinging and the decurtation contraction of hip joints 、ankles of the supporting legs.the swinging leg shows "the calf's active backward swinging"before its landing impact,the skill affects the loss of center of gravity level speed when the swinging leg lands.they enlarge their trunks' forward-landing impact phase ,it can decrease the center of gravity level speed's loss after landing and impel the center of gravity level speed to pass the supporting spot quickly.

两人缓冲阶段身体重心水平速度变化规律是在体前缓冲阶段呈下降趋势；当身体重心垂线超过脚后跟后，在膝关节继续缓冲做退让收缩的情况下身体重心水平速度开始加大，原因是踝关节在最大缓冲时身体重心已移过支撑面及摆动腿膝关节已做体前摆动，主要动力来源于摆动腿的积极前摆和支撑腿髋、踝关节的克制性收缩；在摆动腿下压着地前期是大腿积极下压小腿随大腿的积极下压顺势向前下滑摆，在摆动腿下压着地后期表现出"小腿积极回摆"技术，对减小着地时的水平速度损失、加大向前用力都有积极影响；适当加大摆动下压着地阶段躯干的前倾角度，有利于减少着地时相的速度损失和有利于身体重心较快的移过支撑点；缩小后蹬结束后的后伸动作幅度，有利于减小腾空时间。

It is so simple, that it is almost unbelievable: the first chord is a staccato and the remaining two are legato.

分手的速度如果只到曲子的最终速度是不够的，在合手前，分手弹奏的速度必须要能够比曲子的速度快很多。

The operating range suitable for three-phase reaction was obtained and a mathematical model established. The results show that MSB formed by fine magnetizable powder and fliudizing flow can be operated stably in a wide range. MSB has three kinds of regimes: particulate, chain, and magnetically condensed. In these regimes, the chain regime is the best for three-phase reaction. When Ni-RE-P catalyst particles mixed with some iron powder, magnetically stabilization is easily achieved; therefore, it is possible that NiRE-P catalyst can be controlled in the bed for reaction more easilly if adding certain percentage of iron powder.

研究结果表明：细粉铁磁性颗粒形成的磁稳定床可在较宽流速范围内稳定操作，该磁稳定床有三种操作状态：散粒状态，链式状态和磁聚状态，其中有利于进行气液固三相反应的操作状态是链式状态；当磁稳定床在最小流化速度和带出速度之间操作时，床层处于链式状态；最小流化速度和带出速度可用（1-24）、（1-25）、（1-27）、（1-33）式计算；弱软磁性Ni-RE-P非晶催化剂中混入定量铁粉颗粒后便可形成磁稳定床，因此利用混入铁粉颗粒在外加磁场作用下控制弱磁性非晶催化剂颗粒进行反应的方法是可能的。

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.

计算结果表明：采用本文的计算方法可以模拟出火花型激励器喷射、吸入的工作阶段；电火花瞬间能量的输入产生了腔体内的高温、高压环境，从而诱发合成射流的形成；当激励能量增加，激励器产生的合成射流速度增加，可达到超声速状态；周期性激励下，火花型合成喷喷口处的轴向平均速度随时间不是正弦分布，且喷射过程的最大速度要远远大于吸收过程的最大速度。

The sinking rate of the spherical heavy solid in static liquid is in accord with Stocks formula.The plutonic inclusions in igneous rocks which formed as a result of solidification of magma have the same relation as magma.

静态流体中的球形固体重物的沉降速度服从Stocks公式，岩浆岩是由岩浆上升冷凝而成，在形成时与其中的深源包体也是这种关系，只是包体没有沉下去，反而随岩浆上升，说明岩浆上升速度大于最重最大包体的下沉速度，据此可确定该岩浆岩形成时岩浆流体上升的最小速度并推导出计算公式。

Waterbag, personal dimensions will alter the polar curve.

翼面负荷越大，垂直的速度，前进速度，最大速度和小速度也越大。

Tt suggests the high jumpers should improve the stability of approach steps in the foundation of improving the approach speed and adjust the final stride. Comparing with the foreign ones, the Chinese high jumpers have certain margins in the horizontal velocity of barycenter. Their power of supporting and stretching the leg are of a sort, so they should add to their quick power training of take-off leg.

建议运动员在应在助跑速度普遍提高的基础上，着重改善助跑节奏的练习，使之趋向合理；我国部分优秀运动员的助跑质心水平速度、水平速度与垂直速度转化方面还存有差距，应注意加强起跳腿快速力量的训练，特别是支撑力量的训练。

He is the most remarkable man that I have ever known.
