结果表明，在天然金刚石中存在类质同象置换现象，其振动光谱特征随置换元素的不同而不同。

The results show that isomorphous substitution occur in the diamonds and the vibrational spectra characteristics of the diamonds depend on the substitution of different elements.

通过研究特殊四阶幻方的变换，结合对称群中的置换元素相互作用生成的轮换关系，给出了192阶和384阶变换群。

We will manifest the existence of the transformation groups of order 192 and 384 by studying the transformations and rotation relations.
