X射线衍射,目前在研究结晶物质及某些非结晶物质的结构方面,得到了广泛的应用。但就其对试样的照相方法来说,基本上不外乎这样三种形式:透射、背射、掠射。从目前使用来看,透射、背射两种方法用得较多,掠射用得较少。掠射法又称表面反射法,或称小角度法,其观察的范围主要是低指数的几条衍射 X-ray diffraction, currently in the study of crystalline materials and some non-crystalline structure of the material, has been widely used. However, in terms of its method of photography of the sample, there are basically no more than three forms: transmission, backfire, grazing. From the current point of view, transmission, back-shot two methods used more, grazing with less. Grazing method, also known as surface reflection method, or small angle method, the scope of its observation is mainly the low index of several diffraction
