利用声阻法对蜂窝结构钎焊接头质量进行了检测。按照相关标准制作了含人工缺陷的试件，根据声阻检测原理得到检测信号并确定了手动检测工艺。利用手写板提取探头位置信号，通过VC++.NET编写的检测程序与相应的检测信号结合生成声阻C扫描图像，并与超声C扫描检测结果进行对比。试验表明，声阻法工艺简单，检测速度快，可分辨蜂窝结构中约 10 mm的未焊合缺陷。声阻C扫描图像可显示缺陷位置及大小，且其精度达到检测要求。

he brazed joint of honeycomb structure was tested by acoustic impedance method. The sample with artificial defects was made according to the standard; the testing signal was obtained based on the principle of acoustic impedance test, and then the manual testing process was determined. The -scan image was obtained by combining the location signal of the probe picked up by the handwriting board and the corresponding testing signal by a C++.NET program, and the image was compared with the ultrasonic C-scan result. It was shown that the test process of acoustic impedance method was easy to obtain, and has a high testing speed. The  10 mm debond in the honeycomb structure can be detected by this method. The location and size of the artificial defects was shown in the acoustic impedance C-scan image, and the resolution met the test requirement.
