X射线定性相分析是X射线衍射实验室中最常用的技术之一,是工业生产和科学研究工作中进行物相鉴定的一项重要手段。根据衍射花样的线条位置及相对强度,对照标准卡片(粉末衍射卡组,通称ASTM卡片),对较简单的样品(其中仅含一个或两个物相)进行定性相分析,是比较方便的。有关这方面的实验手续及分析方法,在一般X射线衍射书中均有较详细的叙述,可供参考。但是,我们X射线衍射工作者有时会遇到一些样品,在它里面含有三、四个或更多的 X-ray qualitative phase analysis is one of the most commonly used techniques in X-ray diffraction laboratories and is an important means of identifying phases in industrial production and scientific research. Depending on the line position and relative intensity of the diffraction pattern, it is convenient to compare a standard card (powder diffraction card set, commonly known as ASTM card) to a simpler sample (with only one or two phases) for qualitative phase analysis. The experimental procedures and analysis methods in this area are described in more detail in the general X-ray diffraction book for reference. However, we sometimes encounter X-ray diffraction samples in which there are three, four, or more
