The determination of composition of Ag film on X-ray diffractometer is presented. The asymmetrical Bragg reflection STD scan mode with the conventional X-ray diffraction CBD mode is used to determine phsae composition and orientation of Ag film.

• 利用不对称布拉格反射STD(sampletiltingdiffraction)扫描模式与常规CBD(conventionalBraggdiffraction)扫描模式,确定Ag膜的结构及取向。
