摘要
介绍自相关在超声波透射检测 HK-4 0炉管裂纹中的应用 .研究表明 ,人工裂纹深度 D与接收信号的自相关函数 R有较好的对应关系 。
The application of autocorrelation to the ultrasonic testing cracks of HK\|40 furnace tube is described. The research shows that the depths of the man\|made cracks are related to the autocorrelations of the accepted signals, which is of great importance to the quantity of the crack.
