摘　　要：利用日光和紫外光对黑色签字笔字迹样本进行了光老化处理,通过区带毛细管电泳法分析了签字笔字迹墨水提取液,二极管阵列检测器记录了190～600nm波长范围内的物质吸收峰,用电泳图中不同波长不同迁移时间的电泳峰面积之比对老化时间作图,得出了墨水中不同染料间含量的相对变化关系相对于老化时间的变化规律。同时也对自然老化的签字笔样品随书写时间的变化规律进行了研究。The aging of roller pen ink entries was accelerated in sunlight and ultraviolet, and the extracts of roller pen inks on paper were analyzed by capillary zone eleetrophoresis, photo diode array （PDA） detector. Scanning range of 190-600 nm was adopted in experiment and the change curves were obtained by the plot of the ratio of peak areas in electrophoretogram vs. accelerated aging. The rule of accelerated aging of roller pen ink was investigated by relative changes in content between different dyes in inks. In addition, the relative writing age of roller pen entries was investigated.
