Take the method of "subarea" and "conjunction" to segment the whole request model to three parts. Making use of boundary continuousness between medium and lining structure at stress and displacement, construct a wave function that can satisfy the stress boundary condition at horizontal surface by the scattering of SH-waves in circular part. And then, availing of the wave function, conjoin the circular part into the semi-circular hollow space at common boundary. The problem can be reduced to solve the question that can only meet the condition of "conjunction". Finally, the solution of the problem can be summarized to a series of algebraic equations and solved numerically by truncating the finite terms of the infinite algebraic equations.

采用"分区"与"契合"的方法，将整个求解区域分割成三部分，利用介质与衬砌结构在边界上的应力、位移的连续性，构造一个可以自动满足水平界面上应力边界条件的圆域对SH波散射的波函数；再利用这一波函数将圆域与半圆形凹陷半空间的"公共边界"进行"契合"，将问题简化成对一个只需满足'契合'边界条件的散射问题的求解；最终归结为对一组无穷代数方程组的求解问题，利用截断有限项的方法对其进行计算。

This system uses FPGA chips as its control center, combined DDS technology this system directly forms SPWM modulated waves to drive contradictorily changed device of IGBT, by changing the range of sine wave to adjust the output voltage to achieve energy saving effect.

本系统利用 FPGA芯片作为控制核心，结合 DDS技术直接形成 SPWM调制波来驱动 IGBT逆变器，通过改变正弦波的幅度来调整输出电压，实现节能效果。

In the first part, turbulent motion in convection zone as source to generate Alfven waves is studied following Lighthill-Stein theory, in which the turbulent source was described by nonlinear terms in MHD equations.

第一个方面主要地研究了加热日冕的Alfven波源。我们采用Lighthill-Stein理论分析了对流层中的湍流运动对扭转Alfven波的激发作用。

In addition we establish a new moving coordinate system in the neighborhood of the wave front and obtain a revised eikonal equation describing the curvature effect of waves in the usual orthogonal coordinate system.

由此我们获得了二维和三维情形下靶型波的具体形式。对三维涡卷波和V-形波，我们也给出了它们的具体形式。在第四章，我们应用摄动方法，较简捷地获得了组织中心沿径向和轴向的运动规律。

But gradually I got into the way of the thing, and guided my coracle among the waves, with only now and then a blow upon her bows and a dash of foam in my face.

不过我渐渐掌握了这玩意儿的脾气，驾着它在浪涛间穿行，只有偶尔从船头打进来的浪花会将一股飞沫喷到我的脸上。

Once I shipped a sea so heavy that I had to stop and bale, with my heart fluttering like a bird; but gradually I got into the way of the thing, and guided my coracle among the waves, with only now and then a blow upon her bows and a dash of foam in my face.

有一次一个大浪冲过来使小艇积了许多水，使我不得不停下来，心里焦急得像揣着小兔子似地往外舀水。但我已逐渐习惯了，能够划着小艇在波浪中上下滑行，只是偶尔有点水从船头泼过来，溅起一股飞沫喷在我脸上。

What we are going to look for are waves in the corona.

"我们准备寻找的是太阳光环的波段。"

We try to find a correction to the frequency of waves.

我们试图找出对波的频率的改正量。

Wavelength: Distance between corresponding points of two consecutive waves.

波长：波的相邻两对应点之间的距离。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
