本文利用傅里叶变换红外显微光谱法（ＦＴ－ＩＲＭｉｃｒｏｓｐｅｃｔｒｏｍ ｅｔｒｙ）对１０８种不同蓝色圆珠笔油墨色痕进行了系统分析。结果表明： 各种油墨混合成分结构的差异遵循一定的规律； 据其红外光谱的特征吸收，大体可将这些圆珠笔油墨分为两大类１８ 种。该方法具有快速、准确、灵敏度高和不损坏样品等特点
In this paper, FT-IR microspectroscopy was used to systematically analyze 108 different blue ballpoint pen ink marks. The results show that: the differences of the composition of the various ink components follow a certain rule; according to the characteristic absorption of the infrared spectrum, these ballpoint pen inks can be divided into 18 major categories and 18 types. The method is fast, accurate, sensitive and does not damage the sample and so on
