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。

According to the problems and shortages exited in the first national judicial cxalnination,author suggests that the system sheRid be perfected in the following three aspects:first,on the basis of lower condition for the entrance of the examination and lower matriculating score,We should keep the balance of right and obligation;second,we could deepen the judicial officials and personal system at the turning point of establishing the national judicial examination system;third,We should perfect the existing judicial unitary examination system through the combination of unitary examination and unitary study so that the purpose of practicing the national judicial examination system can be fulfilled much better.

针对首届国家统一司法考试存在的问题及不足，笔者建议从三处着手进行完善：首先，在放宽报名条件和降低录取分数线上应讲求&权义平衡&；其次，以国家司法统一考试制度为契机深化司法官人事制度改革；最后，以&统一考试+统一研修&的结合来完善现行的司法统一考试制度，使国家实行司法统一考试制度的目的能更好地实现。

Essentially, it is concerned with the improvement of national structure so in pushing forward the constitutionality, we should avoid the following theoretical misunderstandings: our national structure is unitary; federal system advocates the principle of "double sovereignties"; compared with federal system, unitary system has the more authoritative central; we should stick to the unitary system to improve our national structure.

中央与地方关系的法治化问题在实质上就是国家结构形式的完善问题，在推进中央与地方关系法治化的过程中，应当注意走出国家结构形式的几个理论误区：我国的国家结构形式是单一制；联邦制奉行的是&双重主权&原则；单一制与联邦制相比，中央更具权威；完善国家结构形式，我们必须坚持单一制。

The three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.

Results l.Serum concentrations of VCAM-1 in PIH (93.39 + 57.3)ug/ml were higher than that in normal pregnant group. Serum concentrations of VCAM-1 in moderate(97.89 + 34.07)ug/ml and severe PIH(132.24 + 60.97)ug/ml were significantly higher than that in normal group.(P.05, P.01). There was no difference between serum levels of VCAM-1 mild PIH and normal pregnant group. 2.Serum levels of IL-6 in PIH group(102.17 ?48. 31)pg/ml were significantly higher than that in normal group(49.16 + 12.9)pg/ml.Serum levels of IL-6 in moderate(95.79+31.19)pg/ml and severe PIH( 127.27+11.3 8)pg,ml were significantly higher than that in normal group. There was no difference between serum levels of PIH in mild PIH (52.13 + 12.90)pg/ml and normal pregnant group. 3. In PIH group, serum concentrations of VCAM-1 correlate with the levels of IL-6,r=0.63. 4.The expression of VCAM-1 in cytotrophoblast of spiral arteries in normal pregnant group(100%) were significantly higher than that in PIH group.Theexpression of VCAM-1 in moderate PIH(37.50%) and sever PIH were lower than that in normal group.There was no difference between the mild PIH and normal group.Conclusions The increased levels of serum of VCAM-1 may participate in the process of vascular endothelium damages in PIH.

24H treatment group compared with 24h model group: the density of light of HSP70 of the group increased and which of TGF-β〓, is not different with the model group; the density of the light the HSP70 of the Baicalin group increased and which of it the TGF-β〓, increased with the model group; the density of light of the Concha Margatitifera Usta is not different and which of TGF-β〓, increased with the model group; the density of light of the Cholic Acid group is not different and the density of light of it of TGF-β〓 increased with the model group; the density of light of the Hefang Group is not different and which of TGF-β〓 is not different than the model group.

合方治疗脑缺血12小时组缺血脑组织TGF-β1光密度值较缺血12小时模型组无显著性差异（p＞0.05）。本实验结果发现，与单纯缺血12小时、24小时大鼠相比，药物干预组缺血侧大脑皮层TGF-β1免疫反应明显增强，计算机辅助图像半定量分析两组间缺血侧大脑皮层TGF-β1免疫阳性细胞数差异非常显著。说明药物对局灶性脑缺血损伤可能有一定保护作用，其机制可能与诱导脑细胞TGF-β1合成增加有关。然而，药物调控TGF-β1表达，其促TGF-β1表达增强的机制可能是这样的：脑缺血时TGF-β1mRNA表达增加可能与缺氧诱导神经和胶质细胞刺激生长因子表达有关。
