摘要/Abstract

摘要： 将分形理论用于仪器分析信号的解析,提出一种面向分析谱图中重叠信号处理的分形分辨算法.通过对信号进行分形分析,采用分形维数可有效地反映信号的特征,准确地得到谱峰个数和位置的信息,避免人为判断的误差,实现重叠复合信号的分辨.实验表明,这种新的重叠谱峰分辨法能用于光谱、电化学、色谱等仪器分析数据的处理

Abstract: A novel overlapping peaks diagram oriented analytical algorithm, named fractal resolving method(FRM), which is based on the fractal theory, is proposed to process analytical signal from instrument. By calculating the fractal dimension of the signal, which can effectively reflect the characteristic of each signal, the information of the peak numbers and peak positions can be accurately obtained. The method will avoid the error generated by man-made estimate and fulfilling the separation of the overlapping peak signals. The experiment results showed that FRM was a powerful tool for processing the peaks signal.

Key words: Fractal resolving method, Overlapping peaks signal, Fractal dimension
