下压

Due to the symmetry of the plate, there are symmetric and antisymmetric mode vibrations with respect to the median plane of the plate.

首先建立了在偏压电场作用下压电介质的运动微分方程，进而根据对称模态和反对称模态的特点，分别在自由表面电学开路和电学短路情况下得到了Lamb波传播的相速度方程。

Don't force your shoulders down when working at the barre.

注意事项三：在做把杆练习时不要把肩膀过分下压。

实验数据表明，通过毛细管的热流对λ转变温度测量值有一定的下压作用，其数值为 10 0 μW下压量为 0 。38mK 。

Eventually the long front torso will rest down on the thigh. Hold your maximum position for 15 to 30 seconds, then come up with an inhalation by pressing actively through the back heel and dragging the coccyx first down and then into the pelvis. Then go to the left side.

最终将身体全部靠近大腿上，保持您的最好的位置15至30秒，然后当你要起身时下一个吸气，后脚跟主动向下压，尾骨先向下臀部回正，然后进行左侧。

Massage for detumescence: Press five fingers over eye socket. Move fingers up and down between eyebrow and eyelid, then between tip of the eyebrow and temple.

按摩消肿法：用五指按住眼眶，慢慢从眉毛到眼皮做下压和上拨的动作，再从太阳穴至眉尖。

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 mainly concentrates on the trainee's coax outside open to fix the foot position tortured by benting the knees joint to be lower to-145 degree.

主要着重于髋关节的外开固定训练者的脚型位下压漆关节，下压漆关节最低可至-145°，训练者根据自身的条件自行调节合适的高度。

The plunging function on a plunge router can easily deal with mortising needs, but unfortunately is only seen on larger and more expensive routers. Trim routers on the other hand, although as a member of the router family, lack this plunging functions.

木工下压式路达可以轻松处理榫槽的需求，但通常仅在较贵的大型路达有此下压功能，身为小型路达的手提修边机却无此功能。
