| 摘 要： | 分析了复合材料微波检测中电磁参量、电磁波频率和介质薄片厚度的计算方法。基于复合材料媒质间的电磁传播特性，提出了微波无损检测技术应用于复合材料检测时的局限性和不足。给出了由于脱粘空气层引入后，透射波振幅减小和相位延迟的解决方法。推导了层间脱粘将会改变总的传输系数的结果，对今后复合材料微波检测工作的方向进行了探讨。

| Abstract: | The computation methods of electromagnetism parameters, electromagnetic wave frequency and medium slice thickness in microwave measuring for composite material were analyzed. According to the spreading characteristic of electromagnetic wave, the limitation and deficiency of microwave measuring in composite material were pointed out. Due to the effect of the air layer in the composite material, the swing attenuation and phase delay of transition wave and the solutions were discussed. The transmission coefficient was calculated with the effect of air layer in composite material. The developing tendency of microwave measuring in composite material was discussed. |
