| 摘 要： | 应用经验模式分解（EMD）将恒电量瞬态响应信号分解为不同时间尺度的内在模函数（IMF）分量。去除其中的小时间尺度的干扰噪声分量。然后经过拉普拉斯变换获得恒电量频谱以研究电化学腐蚀过程。

| Abstract: | A method based on empirical mode decomposition (EMD) to denoise coulostatically induced transient signals is presented. In this method, noisy data can be extracted in the small time scale of IMFs. By applying Laplace transform techniques to the coulostatic response, it is possible to obtain the coulostatic spectrum. Practically, the proposed method can contribute to analysing corrosion systems effectively. |
