查询词典 wave

The secret to this system lies in the analysis of the earthquake, which actually generate two waves,the first is a smaller primary wave that travels 7 km/s, the second wave, the one that can cause damage, moves slight slower, 4km/s .

这个系统的秘密就在于对于地震的剖析。地震由两种震波组成，第一种小一点的主要震波以每秒7公里的速度传播，而第二种，就是能造成破坏的那一种，以相对慢一些的每秒4公里的速度传播。

The difficulties during developing this technique is that dielectric loss tangent measured is very small, and many factors influence the high-precision measuring, such as the excursion of the primary wave on power line, the existence of the harmonious wave, and the electromagnetic interference in the field and so on.

该检测技术的难点在于待测介质损耗角很小，电网基波频率不稳、高次谐波的存在以及现场电磁干扰等因素都会影响测量准确度的提高。

Based on the analysis on primary wave frequency characteristics, some conclusions can be obtained: there were variations obviously for the characteristics of primary wave frequency spectrum in fracture zones, such as the dominant frequency shifted towards the low frequency, at this location the amplitude increased rapidly, and there were significant differences from the surrounding unbroken rocks.

通过对纵波频谱特征的分析得到这样的认识：对于断裂构造，纵波的频谱特征有着明显的变化，如纵波的主频位置向低频偏移，在低频位置上其幅度急剧地增大，与上下未破碎的岩层有着非常明显的差别。

It can be used to demonstrate such as optical axis of the uniaxial crystal,principal plane,the ordinary wave front and the extraordinary wave front ,etc.

该仪器用于普通物理光学教学，能形象生动地演示单轴晶体中的光轴、主平面、o光和e光的波面、o光和e光各自的电矢量的振动方向、速率大小关系，并能灵活地结合课堂教学各种实例，说明在不同条件下，双折射的产生及其原因

The development of Wave Mechanics goes back to ancient times. The principle of least action is the source of Wave Mechanics, so it is the mother of several principles.

波动力学的发展源远流长，最早发端于最小作用原理，该原理可以说是"众理之母"。

Based on the experimental results, the wave height of progressive wave decreases gradually with the increase of the distance of artificial reef.

量测结果显示，当波浪於潜礁上方碎波时，波高有明显的减衰现象并随著向下游传递距离增加波高减衰情况越显著。

In most previous investigations for the seabed-pipeline interaction, the seabed has been taken as to be elastic and generally the influences of the non-linearity of progressive wave loading and stand wave loading have been overlooked.

目前大多数研究只是考虑了管线、海床在线性推进波作用下的响应，没有考虑波浪非线性对于管线及其周围海床响应的影响，也没有考虑立波波浪荷载作用下管线及其周围海床响应。

Finally, the model was used to investigate the characteristics of hydrodynamic and salinity distributions in the Houlong River estuary. The estuary exhibits the mixed of progressive wave and standing wave.

模式亦模拟不同上游淡水流量时，盐分入侵距离，再经由线性回归建立不同淡水流量与盐分入侵距离之关系。

Pn 2.3.3 Standing Waves or Resonances When a free progressive wave encounters a sharp change in impedance such as at an air-hardwall boundary, and if the angle of incidence is normal, then the reflected wave travels back along the original path of propagation with a 360 ° change in phase.

pn 2.3.3 驻波和共振当自由行波遇到波阻突变时，比如遇到气壁边界，若入射角度垂直于边界，那么反射波会沿原路径返回，相位变化360°。

This will create a wave that is more complex than a pure sine wave.

这将产生一个比纯正弦波更复杂的波。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
