Abstract: 90 experimental samples written under different conditions by 3 writers with 5 gel-ink pens were investigated to study the stability of stroke marks.The influent factors such as the writing speed, writing posture, writing underlay, paper's diffusing effect and pen's oldness were tested and the changing rules of characteristics of stroke marks were summarized.The results could be used for reference in comparison of handwriting written by gel-ink pens.

摘要： 在阐明中性笔特点的基础上,通过对3位书写人用5支中性笔书写的90份实验材料的放大观察与测量,探讨中性笔笔痕特征在书写速度、书写姿势、书写衬垫物软硬、纸张洇散程度以及书写笔新旧程度不同时笔痕特征稳定性的具体表现,并分析影响笔痕特征稳定性的主要因素及变化规律。掌握影响中性笔笔痕特征稳定性具体因素及其变化规律,是有效利用中性笔笔痕特征进行笔迹鉴定的重要前提。
