When the primary air blast wave from the explosion strikes the ground, another blast wave is produced by reflection.

当爆炸引起的入射冲击波触及地面时，由于波的反射便产生另一冲击波。

Wave energy tends to transfer mainly from the primary wave with highest frequency to other two waves, which isn't completely consistent with the resonant interaction.

能量传递方向主要表现为从高频的主波向次波和生成波转移，这与共振相互作用不完全相同。

The first is a smaller, primary wave that travels at seven kilometers per second. The second wave, the one that can cause damage, moves at a slower four kilometers per second.

地震实际上会产生两种波，第一种是以每秒7公里传播的较小的初级波；第二种波则是能造成毁坏的波，以每秒4公里的速度传播，速度较慢。

As the variation of QRS complex wave is the primary reference criteria on clinical diagnosis of arrhythmia, exact extraction of the features of QRS complex wave is the key problem.

QRS复合波群的形态变化是心律失常临床诊断的重要参考标准，因而准确地提取QRS复合波群的波形特征是心律失常自动化诊断中面临的关键问题。

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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
