Abstract: Objective To detect the glycerin in gel ink entries and study its dynamic change. Method The entries made by 20 gel inks containing glycerin were analyzed by gas chromatography. Ink entries of three inks， whose content of glycerin were quite different from one another， made at different time points were analyzed. Results The aging curves of glycerin in three ink samples were formed. Conclusion According to the curves， the inflection point of glycerin in different inks appear in 6 months after written. After 6 months， the content of glycerin tends to remain unchanged.

摘要： 目的 对中性墨水笔墨迹中甘油成分和随时间变化规律进行研究。方法 利用气相色谱法分析了含有甘油溶剂成分的中性墨水笔字迹墨迹，并对甘油成分含量相差较大的字迹样本的变化规律进行了研究。结果 得到了3种字迹墨迹中甘油成分随字迹形成时间变化的关系曲线。结论 曲线变化规律表明，书写时间6个月的中性墨水笔墨迹中甘油成分的含量变化出现拐点，6个月以后甘油成分的含量基本趋于不变。
