As same as the above-mentioned reason, because theconditions at the inside straight boundary of the binarycomposite material can not be easily satisfied, here, anelastic circular inclusion with large radius is used to replacethe upper half space of the binary composite material, so the〓mary binary composite mater ial problem can be changed〓the scattering problem of a circular elastic inclusion andto the scattering problem of a circular eastic inclusion and〓circular cavity in an infinite space to the steady incident〓wave.

与前面两个问题的理由一样，同样，由于问题中双质复合材料的内部直边界上的边界条件不易解析满足，为此，本文采用了一个半径很大的弹性实夹杂来代替问题中双质复合材料的上半空间部分，而将原来的双质复合材料问题转化成了无限大空间中一圆形弹性夹杂和一圆孔对稳态P波的共同散射问题，根据该问题的特点写出了弹性夹杂内外波场中波函数的一般形式解，利用该问题中夹杂和圆孔处的位移和应力的连续条件，并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的无穷线性代数方程组，在满足一定计算精度的前提下，通过有限项截断进行近似求解，进而讨论了双质复合材料中圆孔边界处的动应力集中系数随不同入射角、圆孔的不同位置、以及入射波的不同无量纲波数的变化和分布情况。

Simulation results indicate that for the Taipei Harbor five wave periods 9.8sec, 5.4sec, 4.1sec, 3.6sec, and 3.2sec incident in WNW direction having resonant impact. Whereas in N and NNE directions there exist no resonance phenomena due to sheltering effects from the north-side breakwater.

在港区码头的共振特性上，结果显示在WNW方向入射的波浪有5个周期T=9.8sec、5.4sec、4.1sec、3.6sec、3.2sec对港区码头的共振影响较为显著，在N向与NNE向则因为有北堤防的遮蔽，因此对於港区码头并没有共振发生。

Through the curve fitting,the almost real angle is obtained,which is used in the correction of the time-lag error.

数值分析的结果表明，通过修正时延偏差能有效地改善弹丸斜入射对定位精度的影响。

In this paper,the influence of oblique shot on time-lag estimation is studied.

在一些射击场合中，弹丸与靶平面并不一定垂直，这时，利用弹道激波测量弹着点时，就需要考虑弹丸斜入射带来的影响。

It is possible to realize the multiple arrival tracking with the multistage technique because the multiple arrivals are different combinations or conjugations of the simple incident, transmitted and reflected waves at the velocity boundaries.

基于多次波是通过速度界面简单的入射、透射、反射及转换波按一定规律及原理的不同组合，因此可实施分区多步计算技术。

The principle of an optical microscope is quite simple; however, the resolving power of an optical microscope is limited by the wavelength of the light employed, being greater when the light source is shorter wavelength.

光学显微镜的原理很简单。但它的分辨率却受到入射光的波长限制。光源波长越短，分辨率越高。

Even bellow the energy threshold for positronium formation, the laser can supply the extra energy to form a Ps atom.
