| 摘 要： | 中性笔墨水色痕形成文件的检验是目前法庭科学实验室经常遇到的问题,文中对市场上收集到的15种不同品牌的中性笔进行了鉴别,采用单点模式无损鉴别的方法区分墨水的色痕。实验结果表明,根据红外特征谱图所形成红外吸收峰的位置、峰的数量、峰的强度及形状和二阶导数光谱可将不同生产厂家或牌号的黑色中性笔墨水区分开来。

| Abstract: | Forensic science laboratories frequently examine documents formed by neutral pen ink marks. This paper collected 15 different brands of neutral pens on the market for the identification by adopting the mode of single point nondestructive identification method to distinguish the ink marks. Experimental results show that according to the position, number, strength, shape of the peak and the second derivative spectra formed by infrared spectrum, black neutral pen ink from different manufacturers or of different brands can be distinguished. |
