摘　　要：According to the main characteristic of sharp peak, the method of spline wavelet combined with spline interpolation interruption filtering analysis is proposed for a sudden change (an unstable) noised signal and is applied in V and Mn CCD-ICP-AEC spectral signal. The satisfactory results show that the new technique is effective-on enhancing the clarity and accuracy of an unstable signal.According to the main characteristic of sharp peak, the method of spline wavelet combined with spline interpolation interruption filtering analysis is proposed for a sudden change (an unstable) noised signal and is applied in V and Mn CCD-ICP-AEC spectral signal.
