传统的谱线平滑方法容易引起谱形畸变,利用匹配滤波器的思想对卷积滑动变换法进行了改进,采用高斯函数叠加指数函数代替高斯函数作为变换函数。改进后的方法既能最大化地抑制涨落,又能较好地保持谱形特征,实例证明了该方法的优越性。
Traditional method of smoothness of gamma-ray spectrometry data gives rise to aberration of spectra curves easily. The article improve convolution sliding transformation using idea of matched filtering. Gauss adding the exponential function instead of Gauss function is used as converting function. The improved method not only suppresses statistical fluctuation mostly but also keeps feature of spectra curves. Instance verified superiority of this new method.
