| 摘 要： | 本文针对圆珠笔字迹相对书写时间的鉴定,参照溶剂提取法,提出一种新的实验技术——溶剂蒸溶法.该方法以检样纸张作为展开板,以乙醇蒸气作为展开剂,通过测定圆珠笔油墨在纸张上的扩散程度来判定圆珠笔字迹的相对书写时间.

| 关 键 词： | 圆珠笔油墨 乙醇 蒸溶 |

| Abstract: | A novel technique to identifying the relative age of ballpoint pen ink - solvent vapor dissolving approach (SVDA) evolved from solvent extraction technique (SET) is presented in this paper. Employing the sample paper as base plate and ethanol as developer, the method detects the relative age of ballpoint ink via measnring the ink diffusion extent (DE)on the paper. |
