可擦中性笔墨水色痕形成文件的检验是目前法庭经常遇到的问题，建立一种简便、灵敏、快速、定性准确的区分可擦中性笔墨水色痕种类的方法是当前公安实战部门所需要的。研究中利用红外显微镜，采用单点模直接采集可擦中性笔墨水色痕的红外光谱。实验结果表明，根据样品红外吸收光表征的红外吸收峰的位置、数目、强度及形状可将不同品牌的可擦中性笔墨水色痕区分开来。
可抆中性筆墨水色痕形成文件的檢驗是目前法庭經常遇到的問題，建立一種簡便、靈敏、快速、定性準確的區分可抆中性筆墨水色痕種類的方法是噹前公安實戰部門所需要的。研究中利用紅外顯微鏡，採用單點模直接採集可抆中性筆墨水色痕的紅外光譜。實驗結果錶明，根據樣品紅外吸收光錶徵的紅外吸收峰的位置、數目、彊度及形狀可將不同品牌的可抆中性筆墨水色痕區分開來。

The court is always confronted with such difficulties as to examine the document with ink stains of erasable gel pen. Therefore, it is necessary to establish a simple, sensitive, rapid and accurately identifying method for the public security organs to distinguish different ink stains of erasable gel pen. The research applies infrared microscope and single point mode to directly collect infrared spectrum of the ink stains of erasable gel pen. The results show that the erasable gel pen ink stains of different brands can be distinguished according to the location, number, intensity and shape of the infrared absorption peak of the sample’s infrared absorption spectrum characteristics.
