- 用该方法去噪既能很好地保持信号突变点的原有特性，又具有较强的去噪能力。
The new denoising method not only preserves signal's original features, but also has stronger ability to remove noise. - 该方法以曲线的曲率公式为理论基础，用相邻点间的半二阶差分对突变点进行自动识别，并将其剔除。
This paper puts forward a kind of fast and effective method of muting value based on the curvature formula, and it can automatically discern mutating data using half two rank difference method and get rid of the false data. - 结合裂纹梁第一阶谐振频率与驱动点位置关系曲线，利用曲线上出现的突变点，准确地识别了梁的损伤状态和裂纹损伤位置。
Combined with the graph correlating the first resonance frequency with driving point location, the method localizes the crack by monitoring a jump in the graph.
