结合核能谱的随机特性,探讨了核能谱的正态组合模拟方法.该方法将核能谱分解为正态分布函数的组合,进而转化为参数化模型,并对正态组合函数进行随机抽样以模拟原始能谱.该方法可以灵活地调整正态函数的个数和各正态函数的标准偏差,以满足模拟中对谱线平滑度、准确度的不同要求,是一种效果较好的参数化模拟方法.

According to the random characteristic of nuclear spectrum,the paper discussed the simulation method based on normality combination in nuclear spectrum simulation.The main idea for this method is to decompose the nuclear spectrum into several normal distribution functions,transform the nuclear spectrum into parametric model,and simulate the orighal spectrnm by random sampling of normality combination function.The standard deviation value and the number of normality function can be adjusted flexibly to satisfy the different spectral line demands of smoothness and accuracy in simulation by this method which is a parametric simulation method with better effect.
