I used to find it difficult to transform the Miller index in close-packed hexagonal (HCP). I mean, it should not be difficult theoretically, but it seems to be hard to understand. Thus, I spend some time to describe it in Matrix Form, in order to make it easy to grasp, and easy to calculate by programming.

材料分析手段是十分丰富的。

笔者认为,材料专业运用最广泛的分析手段之一是谱图类的分析手段。

其中XRD (X-Ray Diffraction,X射线衍射分析)是其中典型代表。其原理可靠,已经过漫长的时间考验,多位学者依靠对其深入研究而获诺贝尔奖项,称之为材料表征界之“元老”也不为过。
