| 摘 要： | 将国产便携式近红外矿物分析仪引入宝玉石无损伤鉴定。通过实测图谱比对,就矿物的近红外光漫反射光谱特征,对主要宝玉石品种的可鉴别性进行分析;对翡翠等作为多矿物集合体表现出的近红外光谱特点及翡翠A货、B货、C货的可区分性亦作了初步分析。实测结果表明,利用易于普及的BJKF-1型近红外矿物分析仪在波长1 300~2 500 nm的近红外测量区域内对黄玉、绿柱石、电气石等部分宝石类,透闪石、叶蜡石、蛇纹石、硬玉等大部分玉石类样品开展日常检测工作,有广阔的应用前景。

| Abstract: | In this article,the application of Chinese BJKF-1 near-infrared(NIR) mineral analyzer to the identification of gemstones and jade nondestructively is reported.By comparing the diffuse reflection NIR spectrum features in the mineral detection,the indentifiability for major gemstones and jades are discussed.And based on the infrared spectrum features of emerald,a kind of gemstone that consists of multiple minerals,the discrimination of type A,type B and type C of emeralds is also discussed.The measurement results indicate that within the spectrum range of 1300～2500 nm,some of the gemstones such as topaz,beryl,tourmaline and the majority of the jades such as tremolite,pyrophyllite,serpentine and jadeite can be indentified.It also shows that the Chinese BJKF-1 near-infrared(NIR) mineral analyzer has a bright application prospect in routine identification of gemstones and jades. |
