笔者结合以往计算年龄的方法在实际运用中误差较大的情况,在工作实践中摸索出一种较为实用、准确的年龄分析法。 1 分析年龄的依据 1.1根据现场上成趟足迹反映的特征去分析 利用每一枚足迹所反映出的步幅、步态特征,对所反映的积极特征和消极特征进行认真的观察、分析研究,根据几个不同的足迹来相互印证其特征的稳定程度,一但发现特征有很大的稳定性(一个特征在几枚足迹的相同部位出现)即可根据该特征的形态和种类及形成机理来确定年龄阶段或范围。比如:成趟足迹中步幅较大,运步利落有力,步角小,步宽窄,其步态特征为前掌压痕重,前尖出现蹬挖痕,积极特征反映明显突出,则可将年
The author combined with the previous method of calculating the actual error in the larger cases, worked out in the practice of a more practical and accurate age analysis. 1 based on the analysis of age 1.1 According to the characteristics of the site into the trip to reflect the characteristics of the use of each footsteps reflected by the pace, gait characteristics, the reflected positive and negative characteristics of the careful observation, analysis, According to several different footprints to verify each other’s degree of stability of its features, but found that the characteristics of a great stability (a feature in the same part of several tracks appear) according to the characteristics of the shape and species and formation mechanism Determine the age stage or range. For example: into the trail of footsteps greater pace, neat and tidy walking, step angle is small, step width is narrow, the gait characteristics of the forefoot indent heavy, the front tip of the tread digging marks, the positive features reflect the obvious, you can year
