【摘要】 为了从环境伽马能谱重叠峰数据中提取各能量特征峰的信息,使用最小二乘高斯拟合算法,开发了全谱数据高斯分解软件。软件界面友好,通过人机交互方式快捷地实现伽马能谱全谱数据重叠峰分解。并应用于现场实测伽马能谱数据的处理,结果表明高斯分解软件能够有效地提取重叠峰中¹³⁷Cs信息,对评价环境中人工核素污染具有重要意义。更多还原

【Abstract】 In order to extract the information of peaks in different energy from the data of overlapping peaks in environmental gamma spectrometer,a spectrum data Gaussian decomposition software was designed based on least-square Gaussian fitting method.The interface of this software is friendly,it can complete the decomposition of overlapping peaks in gamma spectrometer quickly by the way of man-machines interactive.The result of field measured data decomposed by this software indicates that the Gaussian decomposition software can efficiently extract ¹³⁷Cs spectra from overlapping peaks,which has significance to estimate the human nuclide contamination in the environment.更多还原
