速度

The guided wave group velocity was calculated according to the experiment result, and the location of damage was estimated with the group velocity and time of flight.

通过对实验结果的处理分析，计算出导波的群速度，并根据群速度和飞行时间得到了损伤的位置信息。

Phase and group velocity are the important parameters for researching seismic wave propagation and describing the media property, and they are key contents in theory of elastic wave propagation and play a role in theory and application.

相速度和群速度是研究地震波传播规律和描述介质特性的重要参数，是弹性波传播理论中的核心内容，在理论研究和实际应用中有重要作用。

However, contrast is the financial cost but in the third quarter of explosive growth, its growth rate over the first three quarters year-on-year growth rate of doubling, and the ring than the growth rate is also more than the other two charges, Central, almost stagnant growth circumstances an increase of 16.38 percent.

但是，对比的是财务成本，但在第三季的爆炸性增长，其对今年前三季度的增长率同比翻番的增长速度，比增长速度环，也较其他两项指控，中央，几乎停滞增长的情况下，增长百分之16.38。

The influence of several parameters including injection rate of nozzle exit, the ratio of length between nozzle and inner gular tube, the ratio of length between gular tube and it's inner diameter and back pressure on the performance of gas solid injector is analyzed.

分析了喷嘴出口射流速度、喉嘴距、混合管段尺寸及背压等参数对气固喷射器性能的影响，结果表明：存在最佳的喷嘴出口射流速度、喉嘴距以及喉管长与其内径之比使得固气比达到最大值；而背压的增加则不利于提高喷射器性

Darwin likened the hair-trigger speed of the Venus trap's movement—it snaps shut in about a tenth of a second—to the muscle contraction of animals.

捕蝇草叶面上的毛发能在十分之一秒内让叶子闭合，其速度完全可以和动物肌肉收缩的速度相媲美。

The turn speed is measured with an external hall probe and the oscilloscope, this give me a precise measurement, for instance when I insert an 6mm aluminum sheet I can see on the scope the pulse periode increased quickly, this shows that the speed of the motor drops also quickly due to the eddy currents induced in the aluminum sheet.....

转速度是衡量一个外部霍尔探头和示波器，这给我一个精确的测量，例如，当我插入一个6mm的铝板，我可以看到的范围脉搏 periode迅速上升，这表明速度电机也下降很快，由于涡电流致该铝板。。。。。。

The speed for booting up is not so fast as I expected, so do the shutdown, maybe it's only because it do is a PC instead of real handhold device.

启动速度没我想象的那么快，关机速度也是。也许仅仅因为它是PC替代品吧。

In real accidents one drops at relatively low speeds, often less than 10 m/s, because the broken hang glider or collapsed paraglider greatly slow the descent. Rapid deployment of an emergency parachute is indispensable especially for these low speeds.

在实际的事故当中，通常都是飞行员以一个相对较低的速度下坠，通常是低于10米每秒，这是因为坏掉的三角翼或者已经塌陷的主伞大大降低了下坠速度，所以备份伞必须要在这种低速情况下有效迅速的打开。

It was also studied the tissue distribution characteristics of harmine intravenous emulsion in mice.

采用反向透析技术测定了乳剂的体外释药性能，这种释放模型较好地摸拟了体内生物环境，用多个小透析囊巧妙地实现了药物分子与介质中其它成分的直接分离，使含量测定易于进行；实验结果表明，乳剂粒子内药物向介质的释放过程和释放出来的药物分子渗透进入囊的过程均为被动扩散机制，并且药物在乳剂中的相分配不同其体外释药速度，尤其是最初释药阶段的速度存在明显差异（P.05）。

Yet keeping up with population growth and the heady speed of development is an impossible task.

然而，使城市的发展速度与人口的增长速度持平是不可能的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
