下压

An idea for analyzing aproblem of piezoelectric dynamics,that treats the excitation of the electricfield in a piezoelectric media as an external exciting action acting on thepiezoelectric media and simultaneously regards the piezoelectric media as anormal elastic media,is given based on the analysis of the electromechanicalcoupling relationships in the piezoelectric media under dynamic condition.

在分析动态情形下压电介质中机电耦合关系的基础上，提出将压电介质中电场的激励作用处理为作用于压电介质的外界激励作用，同时将压电介质视为普通弹性介质的分析压电动力学问题的思路。

Then, jump down the rail in the middle yourself, push down the two bascule bridges and go all the way to the T-bridge, which you also push down.

然后，跳下来的轨道中间，按下自己两bascule桥梁和走这条路对T-bridge，你还往下压。

Bamabas said not a word, but a vein began to drumbeat high on each temple, and his brow beetled downward until his eyes were the merest slits.

Bamabas什么也没说，但他额上暴出青筋，突起的眉毛也往下压去，直到他的眼睛只剩了细缝。

Improvement measures: fixture bellmouth pressure under the pressure when the deformation of the negative phenomena turned into a picture, production and quality control to use the morning time, full guidance to companies, Follow-up work station if found undesirable phenomenon is similar to the entire batch of back line for heavy industry processing.

改善措施：治具下压时将喇叭口压变形，将该不良现象拍成图片，生产及品管利用早会时间全员宣导，后续工站如发现类似不良现象则整批退产线重工处理。

Security systems, pull-up when the automatic cut-off event of any obstacles; under pressure when the event that any hinderance automatic reversal.

安全防护系统，上拉时遇任何障碍自动停止；下压时遇任何防碍自动反转。

The fiber material is cut to a predetermined length and conveyed pneumatically to a rectangular slot between upper and lower platen members.

纤维材料被切割成预定的长度并采用气动的方式输送到上和下压板间的矩形槽缝中。

The order spatial variation of soil surface compaction was in the land reclaimed five years(68.40%), next was unsubsided land(52.58%) and the lowest was the land being reclaimed(22.01%); in terms of the variation, the soil compaction is higher and the variation is lower to each soil layer of being reclaimed land, and the compaction of the first three layer is lower but the variation is higher to other redamed land, to the fourth layer(22.86～30.48 cm) is higher and variation is lower, and the compaction under the forth layer is nearly stable.

表层土壤压实度空间变异最大的是复垦5 a的土地（变异系数为68.40%），其次是未塌陷土地（52.58%），最小的是正在复垦的土地（22.01%）。从各层的变异情况看，正在复垦的土地各个层次土壤压实度都较大且变异系数较低，其他复垦年限土壤压实度上面3层较小但变异大，至第4层（22.86～30.48 cm）达到较高值，且变异较小，之下压实度基本稳定。

When you squeeze with a finger, a vibration signal is transmitted to you caller's corresponding finger.

当你下压一个手指时，一个振动信号就会传到你的呼叫者的相应的手指上。

Clicking a mouse button also requires fine motor control—without it, the mouse and cursor will inadvertently move, botching the intended action.

单击鼠标上的按键也需要精细运动技能——用你的手指往下压它——如果手没有牢固地靠在桌面上，你在无意地移动鼠标和光标的情况下就无法单击它。

By the time you get to 2 kicks, you'll probably not be able to count the kicks, it's more of a constant kick with the lunging, or pressing down farther with the head and lead arm to make sure you actually go BENEATH the surface.

当你开始2次腿时，你可能就顾不上数踢腿数了，只需要不断踢腿向前扑，或向下压头部和前伸的手臂，以保证你是在水面下。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
