摘　　要：对能谱分析中光电子能谱重叠的原因做了深入地分析,得出了影响光谱质量在于仪器采样率低等原因,在此基础上重点给出了谱峰分离技术的理论依据──卷积法。利用仪器线型函数去卷积和高斯拟合,计算的结果与实验测量结果的对比表明,卷积法在谱线分离技术中的应用是比较成功的,它能使畸变光谱更接近实际光谱,使计算出的物理量更接近实际值,结果更精确。A further study on the cause of maltiphoton spectrum overlapping in the analysis of energy spectra is discussed.The convolutional integral method—the theoretical evidence of the technology about spectral peak separation is supplied.By the contrast between the calculating results and the present measuring results in the experiment,the application of convolutional method in spectral peak separation is proved to be comparatively successful.It is helpful to approach the actual spectrum and thus increases the accuracy for the measurements.
