摘要
应用遗传算法对S-K数字高斯成形重叠脉冲分解的研究与分析.根据核事件与核信号时间间隔的统计特性,提出了成形方法中产生脉冲堆积概率的计算公式和脉冲堆积丢弃概率公式,概率的计算估值误差为±0.22%~±0.24%,结合脉冲堆积概率,量化出了该分解方法对原谱的计数相对于堆积直接丢弃所能达到的能谱计数修正效果.
Aiming at the overlapping pulses in the current nuclear pulse S-K Gaussian forming m ethod,the genetic algorithm is used to study and analyze the overlapping pulse decomposition of S-K digital Gaussian forming.According to the statistical characteristics of the nuclear event and the time interval of the nuclear signal,the calculation formula of the pulse accumulation probability and the pulse accumulation discard probability formula in the forming method are proposed.The calculation error of the probability is ± 0.22%〜± 0.24%,combined with the probability of pulse accumulation.The quantization spectrum correction effect that the decomposition method can achieve on the original spectrum relative to the stack direct discarding is quantified.
