摘要：

目的 司法鉴定实务中指印的同一认定仍主要依靠达到一定数量符合指纹细节特征进行鉴别，然而指印的印面特征和阶段性特征的特定性并不要求其在同一认定过程中需要满足一定的数量，这为指印的同一认定提供了重要依据。通过分析指纹脱皮与脱皮指印特征的变化过程，以达到将其初步应用于鉴定实践的目的。方法 通过对实验对象同一手指同期不同脱皮特征进行显微观察，并用司法鉴定辅助应用系统对脱皮特征进行测量，研究指纹脱皮反映在捺印指印特征中的阶段性变化过程。结果 指纹脱皮发生后，其动态修复的每一阶段都可以在对应的指印中反映出来，脱皮指印特征在一定时期内具有特定性。结论 在司法鉴定实践中，脱皮指印特征不仅对指印同一认定具有重要意义，且可以通过指印中脱皮痕迹的变化趋势推测捺印的相对时间，为文件制作相对时间提供参考价值。

Abstract:

Objective At present, the identification of fingerprints in forensic practice still relies mainly on the identification of fingerprint details that meet a certain number of requirements, however, the specificity of print characteristics and stage characteristics does not require the same identification process to meet a certain number, which provides an important basis for the identification of fingerprints. This paper mainly analyzes the changing process of peeling fingerprint and the characteristics of peeling fingerprint, so as to apply them to the forensic practice. Methods In this paper, the different characteristics of the same finger were observed under microscope, and the characteristics were measured by the auxiliary application system of forensic science, the stage change process of fingerprint peeling reflected in fingerprint characteristics was studied. Results After fingerprint peeling, each stage of its dynamic repairing can be reflected in the corresponding fingerprint, and the characteristics of the peeling fingerprint are specific in a certain period. Conclusion In the practice of forensic science, the characteristics of peeling fingerprint are not only of great importance to the identification of the same fingerprints, but also can be used to estimate the relative time of stamping through the tendency of peeling marks in fingerprints, it also provides the reference value for the relative time of document making.
