收集50名大学生的尺划字书写作为实验样品,运用概率论与数理统计原理的方法对尺划汉字、阿拉伯数字和标点符号的特征变化率进行统计,得出以下结论:汉字尺划笔迹特征稳定性按照错别字特征、偏旁搭配特征、笔画比例、笔画搭配特征、运笔方向特征、笔顺特征降序排列;数字尺划笔迹特征稳定性依照字距特征、形体特征、布局特征、笔顺特征、搭配特征的顺序降序排列;标点符号的安排位置特征比形态特征稳定;在弯曲笔画较多的字及标点符号的尺划笔迹中易出现手写笔画。尺划的汉字、阿拉伯数字和标点符号的特征稳定性及规律特点,对尺划字笔迹检验中特征的分析与准确利用具有参考意义。
Fifty undergraduates’ ruler characters were collected as experimental samples, and the probability of characterization of ruler Chinese characters, Arabic numerals and punctuation characters were statistically calculated by the method of probability theory and mathematical statistics. The following conclusions were drawn: the characteristics of Chinese ruler handwriting were stable According to the characteristics of typos, the features of stroke, strokes and strokes, the characteristics of strokes and strokes, the features of strokes and strokes are arranged in descending order. The stability of strokes of digital ruler is characterized by kurtosis, body, layout, strokes and strokes, Arranged in descending order; punctuation arrangement than the morphological characteristics of the location of stable features; in more curved strokes and punctuation characters more handwriting strokes in the handwriting. The character stability and regularity of ruled Chinese characters, Arabic numerals and punctuation marks have reference significance for the analysis and accurate use of features in ruler handwriting test.
