This chapter clarifies the nested relationship between the matrix family of unitary, orthogonal, Givens, Householder, permutation, and row or column symmetric matrices. A precise correspondence of the singular values and singular vectors between the unitary-symmetric matrix and its mother matrix is derived and proved (hence a fast algorithm of singular value decomposition for unitary-symmetric matrix is straightforwardly obtained), and the corresponding perturbation bound is provided.

该章揭示了酉对称矩阵、正交对称矩阵、 Givens 对称矩阵、 Householder 对称矩阵、置换对称矩阵和行对称矩阵之间的逐级包含关系；推导并证明了，酉对称矩阵的奇异值和奇异向量与母矩阵的奇异值和奇异向量之间的定量关系，据此可得酉对称矩阵奇异值分解的快速算法；给出并证明了摄动矩阵的摄动界。

The results show that chromium doped in the lattice of tin sphene substitutes Cr4+for Sn4+,leading distortion of ［SnO6］ octahedral symmentry.Hence the pigment has a broad absorption peak in the range of visible reflection spectrum, its wavelength is 520 nm. Finally,the colour develops chrome tin pink.

结果表明，由于铬的掺杂，Cr4+置换了锡榍石晶格中的Sn4+，使［SnO6］八面体变形，结果导致色剂在反射光谱的可见光520nm周围形成一条宽的吸收带，从而使釉呈玛瑙红色。
