【摘要】 为了研究软硬程度不同客体上穿鞋足迹特征之间的差异性，文章通过油墨捺印的方式采集软硬程度不同客体上穿鞋足迹的全长、掌宽、跟宽特征并将结果输入SPSS数据处理软件进行统计分析，以探究足迹特征之间的差异反映规律。实验结果表明，就软硬程度不同客体上的穿鞋足迹而言，其足迹全长、掌宽、跟宽特征会随承痕客体的软硬程度不同而变化，具体的变化幅度与承痕客体的软硬程度有关，两者之间存在显著性相关关系，承痕客体的可塑性越强、弹性形变程度越大，足迹特征之间的差异就越明显。该研究意在为刑事技术人员正确地制作足迹样本，更科学合理地解释穿鞋足迹检验鉴定中出现的差异点提供参考。更多还原

【Abstract】 In order to study the differences of footwear impressions on objects with different degrees of hardness and softness, the full length, palm width and heel width of footwear impressions on objects with different degrees of hardness and softness were collected by ink imprinting, and the results were inputted into SPSS data processing software for statistical analysis to explore the differences between the impressions and their reflective patterns.Results show that for the footwear impressions on objects with different degrees of hardness and softness, the full length, palm width and heel width of the impressions vary with the degree of hardness and softness of the objects, and the magnitude of the variation is related to the degree of hardness and softness of the objects.There is a significant correlation between them: the more plastic and elastic the object is, the more obvious the differences between the impressions.This aims at providing a reference for criminal technicians to correctly produce impressions samples and more scientifically and reasonably explain the differences in the identification of footwear impressions.更多还原
