多分辨率分析方法在碘化钠γ谱中的应用

The application of multiresolution analysis method in NaI γ spectroscopy

首先对应用数字信号处理技术处理γ谱数据的可行性作了简要论述,并对碘化钠γ能谱高能端全能峰峰值过低的原因作了理论分析,在此基础上论述了采用多分辨率分析方法解决该问题的可行性。最后,探讨了二次压缩变换(QCC)技术在碘化钠γ能谱处理上的应用。

This paper first discussed the practicability of applying the DSP technical method to the γ energy spectrum data processing. Then the reason that the values of the total-energy peaks in the high energy region of the NaI γ spectrum were always very low was analyzed. According above, the feasibility of applying the multiresolution analysis method to resolving the problem was demonstrated. Finally, a new method named Quadratic Compression Conversion（QCC） applied to processing γ energy spectrum was introduced.
