摆动的

Their speed of the swing leg is lower so that affecting the vertical speed and the buckjump height, so enhancing the fold and the swing power of the swing leg. 4. The coaches value the technical training very much, and the technical trainings are reasonable.

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。

"We were looking at the slow steady swing of the pendulum as it counts the seconds," the younger one said,"and my friend has said it would be easy to stand in front of the clock for one hour, to stand without moving and say 'here it comes, there it goes' as the clock's pendulum swings back and forth."

"我们再看钟摆慢慢摆动计算时间，"年轻一些的人说道，"我朋友说在钟前站一小时很容易，要站着不动，还得在钟摆摆动时说：'摆过来，摆过去'。"

Results Ciliary beat frequency of cultured human nasal epithelial cells is 10.39±1.80 Hz at 25℃. Ciliary beat frequency of different cilia is equal on the same cell, it is also equal from uncinate process and inferior turbinate.

The simulation results show that the improved asway mechanism can complete the asway process in 0.4 s with a more accurate asway angle, which proves that the servo electromotor driven asway mechanism is reasonable and can provide a reliable theoretic basis for optimizing the structure of the laser cutting fracture splitting notch machine.

仿真结果表明，改进后的摆头机构可在0.4s内完成摆头动作，且摆动角度调整方便，说明改进后的摆动机构是较理想的激光头摆动方案，可为连杆初始裂解槽激光加工主机结构优化提供可靠的理论依据。

This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.

本文研究了径向潮流冲量矩M与阿莱现象的关系，得出的结论是：M作用于地轴激发了Chandler摆动；M的变化取决于海水、引潮力和地球自转效应的相互作用；日食或月食期间，在一定的条件下，M变化的非常剧烈，引起Chandler摆动振幅脉冲式的变化，进而引起地球纬度的变化，最终导致地球表面重力加速度的变化；这种变化可以通过傅科摆摆动平面角速度的变化或重力计的示数变化反映出来。

The main technical parameters which decide the movement speed are the ankle angle of the support leg, the horizontal velocity, the hip angle and the support leg's hip joint angle, knee angle and the former support distance at the moment of contact, and the latter leg's hip joint angle, the upper arm's movement scope, the support leg's knee angle, the swing knee's angle, the support leg's hip angle at landing phase, and the ankle angle, the support leg's hip angle, the swing velocity of the former leg, the hip angle of the swing leg and the angle of the landing knee at the pushing phase.
