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 ,这个结果对于缺陷大小的定量有重要参考价值
This paper introduces the application of autocorrelation in the crack detection of HK-40 by ultrasonic transmission.The results show that there is a good correspondence between the artificial crack depth D and the autocorrelation function R of the received signal, and this result is of important reference for the quantitative determination of defect size value
