摘　　要：文中对闪光辐射照相的模糊成象过程进行了计算分析。利用计算分析获得的先验认识 ,提出了用模糊差分滤波法增强闪光辐射照相图象的高频分量 ,以突出边界轮廓 。The fuzzy imaging process of flash radiograph object is analyzed through theoretical computation.By means of a priori knowledge obtained from the computation results,the fuzzy differential filtering technique which enhances high frequency components is developed.After high frequency information is enhanced relatively,the edge contour in radiographs will become sharper than before. Therefore the boundaries of object are measured quantitatively from a burr image.
