摘　　要：介绍了嫦娥一号卫星X射线谱仪能量响应矩阵的计算方法,根据谱仪标定试验的标定数据计算了谱仪各路探测器的能量响应矩阵;根据谱仪的能量响应矩阵由直接解调方法对试验测得的放射源能谱和元素荧光能谱进行了解谱,较好的重现了放射源和各元素的特征能量。We presented in this paper the calculation metrod of the energy response matrix for the detector of the Chang＇E Satellite, with both laboratory measurements and simulations. Using this matrix and the direct demodulation technique we have successfully restored the spectra of the radioactive sources from data collected in the laboratory. This shows that the energy response matrix is reliable.
