关于同一人不同书写速度笔迹变化规律的研究

在笔迹鉴定中,经常会遇到由于检材与样本的书写速度不同,造成二者间的可比性差,给检验和鉴定带来较大的困难。因此,对同一人用不同书写速度造成笔迹变化的规律进行全面、系统的研究,很有必要。文章通过对不同性别、不同年龄、不同职业、不同文化的人群书写速度变化笔迹特征存在的稳定性和可变性进行了统计分析,总结出了同一人速度变化笔迹的规律。研究结果表明,同一人不同书写速度变化的笔迹既具有不变的稳定性特征,也具有可变性特征。

A Study on the Handwriting's Changing Regulation of the Same Person in Different Writing Speed

In handwriting identifications,we always meet some difficulties to the inspection and identification because of the low comparability that is caused by the different handwriting speed of samples. Therefore,a comprehensive and systematic study of the regularity of handwriting variation that caused by different writing speed of the same person is really necessary. Through the statistical analysis of the stability and variability existing in the handwriting features of different genders,ages,occupations or educational levels crowds’ handwriting speed variation,the author of paper summarized the regularity of handwriting variation resulted from the changes of the handwriting speed of one person. Furthermore,the experimental results indicate that the handwriting characteristics of one person＇s different handwriting speeds include stability and variability.
