X射线衍射鉴定宝石方法探讨

The Study on Identifying Gems with X-Rav Diffraction Technigue

应用Ｘ射线衍射仪的γ￣（θ－θ）异步旋转方法和织构测定中的样品旋转机制，使单晶样品在一定角度范围内作主体转动，测出足够多的衍射峰（ｄ７值）．据此对大晶体宝石进行鉴定．以此同时，应用倒易点阵理论对获得的衍射信号和测试数据进行了讨论．

Big crystal gems were identified by X-ray diffracting technique,in whichthe specimens were rotated within a cubic angle by using the function of dissimilar-rotationof aθ-θ and the mechanisin as was used in measing texture,so that adequate diffractedpeaks(d-value)had been acquired.Meantime the corresponding data and informationwere discussed by reciprocal lattice theory.
