摘　　要：目的研究可擦笔字迹色痕的检验方法从而为鉴定实践提供技术支撑。方法应用气相色谱法、溶解法对38种可擦笔字迹以及擦除后的潜在字迹的溶剂成分进行了分析。结果 38支样品根据气相色谱法分析结果可以分为五大类,根据溶解性可以分为四类。色痕被擦除不影响其溶剂的组成及相对含量。结论所建方法为可擦笔潜在字迹的分析提供了技术支撑。Objective To establish a method for the analysis of erasable pen ink entries. Method Visible and erased ink samples of 38 erasable pens were analyzed by gas chromatography and dissolution method. Results 38 inks can be divided into five categories according to the solvent composition. They also can be divided into four categories according to the solubility of visible ink entries. The solvent composition in the ink entries before and after erasement was consistent. Conclusion The established method can be applied in the analysis of latent entries of erasable pen ink.
