摘　　要：为了对武器进行X射线无损检测,必需掌握X射线在炸药中的衰减规律。通过试验测定,利用线性回归方法对不同情况下测得的X射线在某炸药中的穿透率进行拟合,分析拟合结果得出X射线在某炸药中的衰减规律。研究结果表明,X射线在某炸药中的衰减是比较明显的,其衰减规律符合三次方程形式。It is necessary to know well the decay law of X-ray in explosive for radiographic inspection of weapon. The data was obtained by experiment and linear regression method was used to fit the penetration ratio of X-ray in explosive under different conditions. The decay law was obtained by analyzing the fitted results. Test results showed that the decay of X-ray in some kind of explosive was obvious and its law conformed with cubic equation.
