摘　　要：目的建立一种灵敏、准确、无损的黑色圆珠笔交叉笔画书写顺序的检验方法。方法依据黑色圆珠笔油墨的同色异谱特征,利用显微共焦激光拉曼光谱仪进行面扫描成像分析检验。结果即使是差异很小的黑色圆珠笔油墨书写的交叉笔画,经过面扫描成像和图像处理后,也能看到先写笔道的连续性被后写笔道中断。结论拉曼光谱面扫描成像技术能有效判断黑色圆珠笔交叉笔画书写的先后顺序。Objective To establish a sensitive, accurate, non-destructive method for determining writing sequence of black ballpen. Method Based on the metamerism characteristics of black ballpen ink, take a mapping analysis by use of Raman Mapping spectroscopy. Result With Rarnan spectral mapping, it can be seen that the continuity of the first stroke was interrupted by the later one. Conclusion Writing sequence of black ballpen can be determined by using Raman Mapping Spectroscopy.
