| 摘 要： | 结合数值模拟得到的单能光子在HPGe探测器上能量响应函数，用改进的剥谱法对测量得到的连续硬X射线能谱进行解谱。扣除测量谱中康普顿、反散射等效应产生的计数对测量能谱的影响，得到了仅反映探测器对光电效应的能量响应的能谱。最后，通过效率修正，完成了测量谱到实际能谱的还原,为连续硬X射线能谱解析提供了可靠方法。

| Abstract: | The influence of counts caused by non-photoelectric effect in measured contin- uous hard X-ray spectrum was corrected.The pure photoelectric spectrum was obtained using the method of improved spectrum stripping technology accompanied by energy respond function of single-energy photon for HPGe detector which had been got in advance,and the real energy spectrum on measurement site was unfolded from the pho- toelectric spectrum by relative efficiency correction.The reliable method for continuous hard X-ray spectrum scrambling was obtained. |
