摘　　要：目的研究赤足足迹在不同承痕客体上的变化情况。方法通过油墨捺印的方式采集不同承痕体的赤足迹样本,并进行特征比较和误差分析。结果就不同承痕客体上痕迹而言,赤足迹的整体特征和局部特征之间均有一定差异,但误差变化大小跟赤足区域有关。结论赤足迹形态上差异与承痕客体不同有一定关系,在赤足迹检验鉴定中应加以注意。同时,该结论也为今后正确的制作赤足足迹样本,更科学合理的解释赤足检验鉴定中出现的差异点提供参考。Objective To study the changes of barefoot prints on different bearing objects.Method The barefoot prints on different bearing objects were made with printing ink.The characteristic comparison and error analysis were carried out.Results In terms of the different bearing objects,there was a difference between the overall characteristics and the local characteristics of barefoot prints.But the error variation was related to the barefoot print area.Conclusion The variation of the shape of barefoot prints is related to the bearing objects,which should be taken into consideration in the forensic practice.This result also provides reference to the sample preparation of barefoot prints,and the scientific and rational explanation to the footprint variation in the examination of barefoot prints.
