【Abstract】 In this paper, the noise of chromatographic signal has been analyzed by fractal geometry, and the Elman neural network trained in sections has been used to filter noise. The proposed method has obvious advantages over other neural networks and median filter in filtering noise, and the precision of results are much higher.更多还原
