From the shadowgraphs, it is observed that the patterns of a plane incident shock wave reflected from the parabolic reflector can be either a regular reflection or a Mach reflection which depends on the shock wave strength and the reflector geometry.

由流场观察得知，入射震波强度较小、收敛角较小的，震波经反射体的反射型态趋向於正规反射，当入射震波强度增强、收敛角增大时，反射型态则会由马赫反射型态再转为正规反射型态。

The calculated results indicated central wavelength of impurity mode and whole forbidden band move towards shortwave when incidence angles increase. Remotion of impurity mode of P-wave consist with that of S-wave basically.

研究结果表明，杂质模的中心波长及整个光子禁带随入射角的增加逐渐向短波方向移动，P偏振光和S偏振光的杂质模的移动情况基本一致。

Under the control of microprocessor, this pest repeller with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency. It penetrates walls and transmits by the wire within walls and makes all connected wire producing pulse electromagnetic wave. By irritating the nervous systems of pests, it makes them be on the rack, physiology disorganized and the capability of procreation reduced. The pests are driving away as they are compelled to escape.

QC101型微电脑变频驱虫器：由完全内置的震荡器，在微电脑的控制下可产生多重扫描变频脉冲电磁波，它可以穿透墙壁，沿室内的电源线传播，让所有在墙中或建筑物内相通的电线都发出脉冲电磁波，刺激鼠类和其它害虫的神经系统，使老鼠和其它害虫感到极端恐慌，生理功能紊乱，繁殖能力降低，感到无法生存而逃离现场。

In the analysis, a nonlinear wave vibration equation of the thin cylindrical shell including damping and items due to geometric nonlinearities was established and then transformed by Galerkin's method. With different combinations of modes different nonlinear differential equations in modal coordinates were obtained. The Runge Kutta method was used to solve the equations numerically and some features of nonlinear wave vibration were discussed.

在研究过程中，首先，考虑阻尼并引入几何非线性项，建立薄壁圆柱壳的非线性波动方程，然后，采用Galerkin方法对波动方程进行转换，选取不同的模态组合，得到相应模态坐标下的非线性微分方程，最后用Runge-Kutta法进行数值计算并对圆柱壳的非线性波动振动特性进行了分析。

A new strategies for restraining harmonics are presented in the paper, the methods adopt the right carrier frequency and the sine wave superimposed a proper three-time harmonics to make it saddle-shaped wave, produce SPWM waveform to control the inverter switching devices for the on and off .

并提出了一种新的易于工程实现的谐波抑制策略，该方法通过正确选择载波频率和在正弦调制波上叠加一个三次波使之成为鞍形波，产生相应的SPWM波形来控制逆变器开关器件的通断从而改善输出波形。

In comparison, it is proved that the wave functions occuring in the two formalisms are identical, apart from a constant multiple which represents the scalar product of the wave functions of a bare nucleon and a dressed nucleon.

这个常数倍即是物理核子及裸核子的波函数的内乘积。第二，我们讨论了一般的含有二个h函数的Chew-Low方程的解，方程的形式使它们在实轴上在(1，∞)及(-1，-∞)二段上不连续。

By analyzing the result, three most main factors influencing the calculation accuracy are found: the constitution of wave scatter diagram, interpolating the irregular wave and the estimating of roll damping coefficient.

通过分析计算结果提出了影响计算精度的三个最主要的因素：海浪能量谱的构成、不规则波的合成方法、横摇阻尼的估算。

He was also an avid scuba diver, so it's not surprising that Hilary's music is akin to floating in the ocean, wave after wave ...

在我人生最低谷的时候，音乐就象是一条清澈的河，我站在不远处聆听，我知道那始终是河在歌唱，用最自然最。。。

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。
