摘　　要：本文使用图形辅助输入谱峰参数的方法,并采用把谱峰参数转换到[0,100]闭区间和阻尼非线性最小二乘法进行谱线拟合,从而将重迭的 Raman 谱峰分开.程序中阻尼因子的选择,避免了迭代中的发散和可行域之外的假收敛.本程序在 IBM PC/XT 机上,用 TurboPascal 语言编制.A program for resolving overlapping peaks in Raman spectra is proposed.The profile of the resolved peaks is supposed to obey Gaussian function.The program isbased on damping non-linear least-square principle.The primitive wave number at thepeak tip is inputed by moving cursor,and other peak parameters are estimated automati-cally by the program.All of the peak parameters are transformed into the region[0,1].In the peak resolving procedure,the damping factor is multiplied by 10 when any peakparameter is out of the region[0,100].
