国内外学者在利用长骨，牙齿等推断尸体的年龄方面做了大量工作，并取得成果。但在碎尸案，爆炸案，交通事故及飞机失事案件中，利用仅有的残留皮肤推断年龄，只在日本有所报道[1]。本文就164例尸体胸部皮肤的组织切片观察测量，建立回归方程，其计算结果对年龄的推断较为满意 Domestic and foreign scholars have done a great deal of work in using the long bones, teeth and other inferences about the age of the body, and achieved results. However, in the case of mass graves, explosions, traffic accidents and plane crashes, the use of only the residual skin inferred age, only reported in Japan [1]. In this paper, 164 cases of cadaver skin tissue sections were observed and measured, the establishment of regression equation, the calculation results are more satisfied with the age of the inference
