将波谱中各频率之波浪视为单一规则波，用 Snell定率计算其折射角，其结果与实测结果并不一致，表示方向波谱中各频率主方向无法利用规则波之原理以简化条件的方法求出。

The mechanism of spallation is analyzed as a result of the interaction of the unloading wave and reflected stress wave. The propagation of laser-induced stress wave is also further investigated, and the influences of film thickness on spall thickness as well as the time when spallation begins are predicted.

分析了层裂机制，得出靶材是在卸载波及被反射的压力波的共同作用下发生层裂；探讨了激光诱导压力波的传播规律，预测了不同靶厚下的层裂厚度及其对层裂开始时间的影响。

In order to use spectral analysis theory to calculate s econd-order wave forces which naval architectures suffered in the random sea wa ves, the second-order wave forces which naval architectures suffered in any one regular wave or any two regular waves should be calculated firstly.

为了采用谱分析方法预报海洋结构物和船舶在随机海浪中所受的二阶波浪力，必须先求得海洋结构物和船舶在任意单色波和双色波中受到的二阶波浪力。

Combined the application in practice, the detecting effects in wave impedance with spherical wave and artificial wave are discussed.

低应变反射波法在桩基完整性检测技术中愈来愈占有重要的地位，但简便易行的优点也造成了检测结果精确性的不足，本文结合反射波法在实践中的应用，就球面波、人为造成波阻抗变化在检测中的影响等几方面和读者进行探讨。

When you're stressed, your wave is jagged and spiky; when you're relaxed, your wave becomes smooth and consistent, like a sine wave.

当你感到有压力，你的波型变得犬牙交错；当你放松时，你的波浪变得光滑和一致，像一个正弦波。

The fundamental conception of the spin wave, the semi-classical and quantum theory of the spin wave, and the application of the spin wave theory.

自旋波的基本概念，自旋波的半经典理论和量子理论，自旋波理论的应用。

Various signals are an important part of correspondent area. In this area, sine wave, triangle wave and square wave are common signals.

The article adopts sensor, ScienceWorkshop to measure velocity of sound with syntony stationary wave method. Not only the change of sound wave can be heard, but also the change of sound wave with computer can be demonstrated.

文章采用传感器和数据采集接口，利用计算机采集数据，配以专用DataStudio软件，用共振驻波法测量声波的波速，不仅可以听到声音强弱的变化，而且可通过计算机演示波形的变化。

The evolution of the half-peak width of the relative density increment pulse with respect to slow wave also demonstrates the close relation to Δp. Its minimum w〓 decreases with the increase of Δp, which means, slow wave will steepen with the enhancement of Δp and may evolve into slow shock eventually. Numerical results also indicate that the propagation velocity of fast and slow wave increase when Δp increases.

对强扰动情形(Δp＝5)，通过考察相关物理量的径向分布，并借助于对物理量沿波动阵面法向分布的讨论，可以初步判断出由强扰动所造成的慢模磁声波在传播过程中逐渐陡变而演化为慢激波，慢激波在进入日冕前已在色球层中形成，并在此后的传播过程中始终保持这一性质。

But the symmetric axis of TI formation is parallel to the borehole axis in the thesis, the propagation velocity of SV-wave and SH-wave are the same in vertical direction, we can't see the splitting phenomena of shear wave.

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。
