| 摘 要： | 用双透射电离室法测量了Ｘ光机在管电压分别为２５、３０、３５、５０ｋＶ时产生的Ｘ射线在铝中的衰减特性，采用了一种ＬＡＰＬＡＣＥ变换模型，由衰减曲线计算出了相应能量的Ｘ射线能谱．讨论了影响能谱计算结果的主要误差来源

| Abstract: | The attenuation characteristics of the X ray generated by X ray tube is measured by dual transmission ionizing chambers.The Tube voltages are 25kV, 30kV, 35kV and 50kV.We reconstruct the spectra from attenuation data with a Laplace transform pair model.The analysis of error in spectral reconstruction is made. |
