Further,we findalso that groups in Saito's results may be replaced by right groups;secondly we mainly investigatethe semidirect products and wreath products of P-regular semigroups;Finally we shallcharacterize the sandwich matrice of completely simple P-regular semigroups,and investigate thestructure of P-regular semigroup whose C-set satisfies a permutation identity.

在这一章中，首先指出Saito在研究半群的半直积和圈积时，对S的限制是不必要的，证明了Saito结果中群可换为右群；其次，研究P—正则半群的半直积和圈积；最后刻划了完全单P—正则半群的夹心阵和C—集满足置换恒等式的P—正则半群的结构。

Results The learning and memory ability of experimental group was better than that in saline control group (P＜0.01), but there was no significant difference between experimental group and normal control group (P＞0.05).There was significant difference in cytochrome C of hippocamp and frontal lobe between saline control group and the other groups (P＜0.01).The expression of cytochrome C in hippocamp was higher than that in frontal lobe of experimental groups.

The structure of the compound 〓(1) consists of a pentanuclear molecule which is center-symmetric. One W atom is coordinated by four S atoms and two Cu atom. As expected, the Fe atoms are sandwiched between two staggered pentadiene rings. The most interesting aspect of the structure is that Fe-C-P-Cu-P-Cconstitutes a distorted hexagon and Fe-Cu-W-Cu-Fe is nearly in a line.

结构是以W原子为对称中心含有五个金属原子的线型结构，W原子与四个μ〓-S和两个Cu原子配位；Fe原子在两个戊二烯环中间形成一个三明治夹心结构；Fe〓-C〓-P〓-Cu〓-P〓-C〓-构成扭曲的六边形，由于两边1，1'-双二茂铁配体的作用导致Cu-S键的拉长。

There were no significant between-group differences in the incidence of hypotension, absolute arterial blood pressure values (P = 0.73), predelivery median phenylephrine requirements (300[0-1000] in Group P versus 150 [0-850]microg in Group C, P = 0.24), or neonatal outcome as measured by Apgar scores and umbilical arterial and venous blood gas values.

Results Of 355 ears in 200 children with secretory otitis media, 240 ears exhibited type B tympanogram and 115 ears type C. Removal of hydrotympanum was performed in 355 ears. There was no significant difference in total obtaining liquid rate (P＞0.05). However, there was very significant differences in obtaining mucus rate, stapedius muscle reflex and recurrence rate (P＜0.01), and a significant difference in obtaining serous rate (P＜0.05). There was no misdiagnosis and missed diagnosis in 200 sick children undergoing acoustic immitance determination.

结果 200例（355耳）分泌性中耳炎患儿呈B型鼓室导抗图240耳，C型鼓室导抗图115耳，分别对其抽出鼓室积液，它们的总得液率无显著性差异（P＞0.05），但其得粘液率、镫骨肌反射、复发率有极显著性意义（P＜0.01），得浆液率有显著性意义（P＜0.05）；在接受200例声导抗检查的患儿中，无1例发生误诊及漏诊。

The average percent value of G C (49.3%) was less than that of A T (50.7%), there was a bias of the content of G, T in the third codon; The number of transition G-A and T-C were 22, 15 respectively, which were higher than that of transition A-G and C-T, the number of tranversion C-A, T-G is 2 respectively, and other tranversion patterns didnt occur; the probability of transition was higher than that of tranversion , Ts/Tv = 9.5-19, there was the highest number of transition in the third codon. The gamma parameter a of the lst,nd and 3rd codon positions were 0.00572,0.01237 and 1.05239 respectively, they showed that there was adifferent substitution rate at different codon position. Frequences of synonymous codon usage were relatively biased. The average rates of synonymous and nonsynonymous substitution were 0.0787, 0.0011 respectively, there was a significant difference between dS and dN (Z = 4.713, p.01), and the low ratio( CD = 0.0284 .3) of dN/dS ratio impled that there were selective constraints against the nonsynonymous sites in cyt-b gene, The distribution of nonsynonymous codon substitution pattern related to Grantharm distance indicated that the purified selection at 2nd codon positions was more intensive than that at 1st codon positions. The phylogenetic trees supported the view of the double origin of Chinese goose, which means that domestic Chinese goose was derived from Anser cygnoides and domestic European goose, and Yili was derived from Anser anser.

碱基含量分析可知，序列的G C含量(49.3％)＜A T含量(50.7％)，密码子第三位点的G、T含量都有较强的偏倚性；序列间G→A和T→C的转换数(22次和15次)高于A→G和C→T的转换数(10次和9次)，C→A、T→G颠换数均为2次，其余颠换模式均未发生；转换数明显高于颠换数，Ts／Tv=9.5～19，密码子第三位点的转换数最高，呈现了相当强烈的转换偏倚性；密码子第一、二和三位点的gamma分布参数α值分别为0.00572、0.01237和1.05239，表明密码子第一位点的替换速率变异最大，第二位点次之，第三位点的替换速率变异相对较小；编码同一氨基酸的同义密码子并非随机使用，表现出一定程度的使用偏倚性；同义替换速率和非同义替换速率分别为0.0787和0.0011，dS与dN值间的差异极显著(Z=4.713，p＜0.01)，而ω=0.0284，明显小于0.3，表明雁属鹅细胞色素b基因序列经历了中度净化选择作用；单步非同义替换(Sing-step nonsymonymous codon substitution，SSNCS)分布模式与Grantharm距离之间的关系说明密码子的三个位点所受的净化选择强度不同；构建的最大简约树与邻接树拓扑结构一致，支持中国家鹅的双起源学说，即除伊犁鹅外的其它中国鹅品种起源于鸿雁，伊犁鹅和欧洲的郎德鹅、莱茵鹅起源于灰雁。
