摘要
分析了用声阻的“等效圆板”新概念对粘结层、蜂窝结结构声阻探伤时所出现的异常指示，并辅以激励频率的改变，即可区分小凹坑与脱粘。
Analysis is carried out on the abnormal indications in inspecting bonded layers and honeycomb structures by the concept of "equivalent disc" of acoustic impedance method.Discrimination between small pit areas and debonded areas can be realized by changing exciting frequency.
