摘要
从量化角度分析回墨印章印文阶段性规格特征,探讨该特征作为回墨印章印文形成时间鉴定依据的可行性。利用Auto CAD对一年内回墨印文自然样本的长度和角度进行测量,应用SPSS数据处理软件对测量结果进行处理分析,得出在不同时间范围内的印文规格特征变化规律及变化阈值。通过多人多次重复试验,回墨印文规格特征变化值随盖印时间的增长总体呈增大趋势,但增加值与盖印时间间隔值无直接对应比例关系,规格特征测量结果受环境及人为因素影响较大。可通过回墨印文规格特征变化趋势来辅助检验回墨印章印文盖印时间。
From a quantitative perspective,the stage⁃specific characteristics of ink⁃return seals were ex⁃amined and the feasibility of using these features as a basis for determining the formation time of ink⁃re⁃turn seals was also discussed.Auto CAD was employed to measure the length and angle of natural ink⁃back samples over a one⁃year period,while SPSS data processing software was used to analyze and process the measurement results.The study obtained information on the changing patterns and thresholds of specification characteristics within different time ranges.Through multiple experiments involving vari⁃ous individuals,it was observed that there was an overall increasing trend in variation values for specifi⁃cation features with longer sealing times.However,there was no direct proportional correlation between added value and sealing time intervals.Additionally,it was found that environmental and human factors significantly influenced measurement results for specification features.Consequently,by observing trends in specification characteristics of reinking seals,it is possible to determine their sealing time.
