在裂缝物理模型实验中，通过对模拟的平行排列的垂直裂缝介质中反射纵波的固定偏移距随观测方位变化的结果分析，得出随观测方位变化的旅行时的差异，可以推出同样存在随观测方位变化的动校正速度的差异。

It showed that TPP is superior to bipole pacing in lowering pacing threshold, decreasing pulse breadth, keeping stable pacing and lessening of discomfort of the patients. Bipositive pole pacing is simpler in lowering pacing threshold and gives clearer pacing P wave and thus it is superior to hinegative pole pacing in TPP which is of practical value in TEAP.

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。
