| 摘 要： | 介绍了在低真空模式下扫描电子显微镜配装X射线能量色散谱仪检测宝玉石的原理与方法。对比与评估了宝玉石样品的X射线能量色散谱仪的无标样定量分析数据与其标准数据，讨论了扫描电子显微镜配装X射线能量色散谱仪在宝玉石检测分析中存在的问题。通过与其它宝玉石检测分析仪器如X射线荧光分析仪、X射线粉末衍射仪、傅里叶变换红外光谱仪及激光拉曼光谱仪比较后认为，扫描电子显微镜配装X射线能量色散谱仪对宝玉石无损分析鉴定是最方便、有效的手段之一。

| Abstract: | The principle and method of the gem identification by scanning electron microscope （SEM） with energy-dispersive X-ray speetrometer（EDS） in the low vacuum mode are introduced. The quantitative data without standard samples of EDS is compared and evaluated with that of the standard document data in the paper. Moreover, some problems in the gem identification by using SEM with EDS are also discussed. Furthermore, compared with the other instruments,such as XRF, XRD, FTIR and LRS, the application of SEM with EDS is one of the best convenient and efficient methods in the gem identification. |
