摘　　要： 为探讨枪管R IFLE线表面的变化对弹头磨损的影响,应用分形理论对弹头磨损表面进行了分析研究,并应用结构函数法计算出R IFLE不同程度磨损下的弹头磨损面的分形维数。结果表明:随着R IFLE表面磨损程度的增大,弹头磨损面的分形维数D也将随之发生变化。R IFLE磨损程度不同,弹头磨损面的分形维数不同。因此,分形维数可以作为弹头磨损表面量化检验的参数,通过分析弹头上膛线磨损痕迹面的变化特征可以推断枪支的磨损程度。 In order to discuss the influence of thechange of barrel RIFLE surface on the bullet wear-surface, the topography feature of bullet wear-surface was studied by means of fractal theory, and fractal dimension of bullet wear-surface under different wear of RIFLE surface was calculated by applying structure function method. The result shows that with the increase of RIFLE surface wear due to more bullets shot by a gun,the fractal dimension D of the wear surface on the bullets is changed accordingly. Different wear of RIFLE surface leads to different fractal dimension of bullet wear-surface. Therefore fractal dimension can be used as the quantity examination parameter of bullet wear-surface and the extent of worn-out of discharge guns can be judged through the analysis of the properties of bullet wear-surface.
