【摘要】 利用噪声信号和测试信号对各个尺度上的波谱的不同表现,应用小波理论对漏磁法检测海底管道的腐蚀和缺损情况中的信号噪声进行消除,根据相应的实验得出了一些海底管道缺陷检测的具体特征.更多还原

【Abstract】 Based on the different representation of various scale spectrum noise signals and tesing signals, wavelet theory is used to get rid of the signal noise included in the magnetic flux leakage inspecting of pipelines. The concret features of seabed pipelines defects imspectio are acquired in accordance of the experimental results.更多还原
