摘　　要：近年来,群体暴力事件不断发生,使用砍刀作为打斗工具的频率不断增加,砍刀上面常常留下作案人、被害人等不同物质的重叠指印。通过一系列实验可以很好地将两种不同物质的重叠指印成功分离,从而将没有任何检验价值的重叠指印分离出来,还原证据,为侦查、破案、起诉等司法活动提供关键证据支持。In recent years, group incidents have been arising, in which machetes are frequently used as fighting weapons. It is, therefore, very common that some overlapping fingerprints of the perpetrator＇s, the victim＇s and some other materials are left on them. One could, through a series of experiments, readily and successfully isolate the overlapping marks of two different materials, somp of which are of little inspection value to help restore and provide key evidences in support of criminal investigation, case-solving, prosecution and other judicial activities.

关 键 词：重叠指印 疑难痕迹 照相分离 还原证据
