摘　　要：利用宝石显微镜、红外光谱仪、紫外-可见光谱仪等测试方法对一件充填处理的黄绿色碧玺样品进行测试研究,宝石显微镜下可见糖浆状流动构造,有时可见蓝色闪光;红外光谱见3056cm^(-1)处苯环的特征吸收峰,以及2965cm^(-1)、2925cm^(-1)CH_3、CH_2的反对称伸缩振动致和2872cm^(-1)附近CH_3、CH_2的对称伸缩振动,显示样品进行了环氧树脂的充填处理;紫外-可见光谱仪测试见绿色碧玺的红区普遍吸收。A testing study was made on a yellowish green tourmaline sample using gems microscope, infrared spectrometer and ultraviolet-visible light spectrometer. It shows syrup-like flowing structure and sometimes blue flash under gems microscope; benzene ring characteristic absorption peak at 3056cml as well as antisymmetric stretching vibration ofCH3 and CH2 at 2965cm^-1 and 2925cm^-1, and symmetric stretching vibration of CH3 and CH2 around 2872cm^-1 on infrared spectrometer, indicating a filling treatment by epoxy resin on the sample; universal absorption in red region of green tourmaline on ultraviolet-visible light spectrometer.
