摘　　要：本文旨在研究指纹在不同年龄段的表现特点,特别是目前手印中难以量化的年龄相关特征信息,诸如指纹印痕模糊现象,乳突纹线的边缘形态、匀称程度,进而探索利用手印分析年龄段的具体方法。通过显微镜观察手印,并采用指纹图谱的方式直观展示典型例图,归纳相关形态学特征在不同年龄段的特点和表现。在观察手印档案中不同年龄段的大量手印样本后,总结各年龄段手印的形态学特征,初步形成手印分析年龄的一种具体步骤和方法,并结合实际案例展示这种分析的具体过程。指纹图谱包含了手印样本在相应年龄段的一些典型和非典型的表现,通过对照本文中的图谱可进行手印遗留者年龄的初步分析。本文为手印分析年龄的方法提供了一种研究方向。There are few morphological methods for fingerprint age analysis,and it is not certain that the mastoid line morphology of fingerprint is correlated with age.Through statistical and correlated analysis of quantifiable feature information,it is found that the number of wrinkles and fine line,the density of mastoid line,the width of mastoid line and small furrow,and other indicators are correlated with age,but the use of these indicators is not enough to analyze the age of the hand imprint remnant.The purpose of this paper is to study the performance characteristics of fingerprints in different age groups,especially the age-related characteristic information that is difficult to be quantified in fingermarks at the present stage,such as the fuzzy phenomenon of fingermarks,the symmetry degree of the edge of friction ridges,and the change rule of sweat holes with age.We explore the specific method of age analysis by fingerprints through observing and summarizing.The fingerprints were observed through the microscope,and the typical examples were visually displayed by fingerprint atlas.Fingerprints are extracted from a large number of samples and represent the characteristics of most samples of the corresponding age.In this paper,the characteristics and performance of different age groups are introduced through text,and the characteristics of fingerprinting performance in different age groups are displayed more intuitively and vividly with the fingerprint atlas.After observing a large number of fingerprint samples in different age groups in the fingerprint archives,the morphological characteristics of fingerprint in different age groups were summarized,and the specific steps and methods of age analysis are preliminarily formed.The specific process of such analysis was showed in combination with practical cases.The map of fingerprint contains the various typical and atypical manifestations of the fingermark samples at the corresponding age.Detailed steps are proposed for a morphological method of age analysis using handp
