【摘要】 用红外光谱衰减全反射法（ATR）和扫描电镜法分析了近年来市面上出现的一种可擦中性笔的笔迹及擦拭后导致笔迹消失的原因。结果表明:如果在待判定字迹周围的空白处所采集的红外光谱图中出现1240 cm^-1谱峰,则说明该字迹已被涂改。利用红外衰减全反射法可方便,快速,无损的对此类笔的笔迹进行鉴定。更多还原

【Abstract】 The handwriting of the Frixion Ball Erasable Gel Pen and the handwriting disappearing mechanism by erasing were studied by means of infrared attenuated total reflection method（ATR-FTIR） and SEM.The results showed that the handwriting was altered when the peak of 1 240 cm^-1 appear around the handwriting authenticated.So it was a very convenient,fast and nondestructive method to handwriting authenticatioa更多还原
