| 摘 要： | 分析了中子照像闪烁屏的成像机理，找出了影响成像分辨率的主要参量，建立了计算模型，导出了以ＫＬＡＳＥＮＳ法确定的成像分辨率的方法。在此基础上，用计算机进行数值计算，示得分辨率随几个主要参量变化的关系曲线，计算结果与实验事实吻合良好，该模型的计算方法对Ｘ射线照像，γ射线照像增强屏的研究具有参考价值。

| Abstract: | The image formation mechanism of the neutron radiography scintillation is discussed. The main parameters which affect the resolution of image are listed. A method based on Klasens method is presented for calculating the resolution of image.By numerical calculation the relation curves of resolution versus some main parameters are worked out. The calculated results are in good agreement with the experimental ones. |
