摘要
在进行α能谱分析时,为减少或抑制放射性计数的统计涨落,针对经典方法的不足,提出了基于EMD-DISPO的α能谱平滑滤波处理方法。根据此原理,在MATALB 2012上编程,实现了谱数据的处理。结果表明:平滑后的谱数据效果比经典方法更精准,有助于更准确地进行能谱分析。
In order to filter Statistical fluctuation when the α spectrum is analyzed,α spectrum smoothing method based on EMD-DISPO polynomial is proposed in this paper.The code of spectrum data processing is realized on Matlab according to the smooth method.And the results showed that spectrum data after smoothing has a better effect,which is helpful to analyze α spectrum accurately.
