选用适宜的多分辨分析小波滤波方法对恒电流瞬态技术的响应信号进行处理，滤除 各种噪声干扰，应用于高绝缘性能防护层缺陷的检测.同时设计了采用特定尺度对小幅度正 弦波激励响应信号进行连续小波变换的方法，提取原信号中与激励信号相同频率的真实信息 ，结果较为满意.
Multi-resolution analysis was used to treat the galvanostatic transient response signals of underground pipeline system ,the information was denoised with satis factory result.The continuous wavelet transformation was also introduced to corrosion electrochemistry measurement to pick up the useful information to diag nosis the defect of underground pipeline system from the response of small ampli tude sine current with high disturbance. It was shown that the wavelet transform ation has the good properties of retrieving the useful information from the dist urbed signal.
