Result］ Among 30 AMI patients there were 28 cases whose phase I area and the whole loop area decrease, with phase I centrifugal branch cutting mark and defect etching or wave change appearing, phase V area increasing, altering rate of loop figure being as high as 90%.

结果］30例AMI患者中有28例CADL的Ⅰ相面积及总环面积减小；Ⅰ相离心支出现切迹、缺蚀或波浪状改变；V相面积增大，环形变异率高达90%。

Slide shift fork shaft, mechanical abrasion, such as locking pin is too large, fork bending deformation or face groove with the ring gear grind open.

换档叉轴滑槽、锁销等机件磨蚀过大，拨叉弯曲变形或工作面与齿轮环槽磨旷。

Therefore, the choice of single mode in the examination and the frequency-thick band of mode has been given a particular illumination separately in the paper, following a relative numerical simulation. And a multi-cyclical sine signal modulated by Hanning window is used to simulate the excitation wave, and then an inspected ring of nodes is established to receive the echo, finally how the length of the circumferential cracks, the width of the axial cracks and the degree of the thickness-reduce effect the result is explained through the analysis of the result, further more, the reflection factor in the defect has been calculated.

因此，本文也就单一检测模态的选择以及模态频厚积段的选择分别予以了阐述，并有针对性的进行了数值计算：应用Hanning窗调制的多周期正弦波模拟单音频激励信号，并设置监测质点环接收回波，通过分析说明了管道的周向裂纹、轴向裂纹以及点蚀缺陷对缺陷回波所产生的影响，并进一步计算了缺陷处的反射系数。
