We present linear codes over finite fields with Mannheim weight and prove that those codes can correct one error taken from a cyclic subgroup of the multiplicative group of finite fields, which provide an algebraic approach in coding modulation.

最后讨论了有限域上的Mannheim线性纠错码，证明了当错误取值于有限域乘群的一个循环子群时，面向多维信号的线性分组码可以纠单个错并为码调制提供了一种代数渐进方法。

In this paper, new classes of linear block codes over finite fields of the algebraicinteger ring of quadratic number fields Qd~(1/2 modulo irreducible elements with norm p or p~2 are presented. These codes can correct one error which takes from the cyclic subgroup of the multiplicative group of the finite fields. The results presented in this paper extend the corresponding results of previous papers.

在处理适用于二维信号的线性分组码时，我们考虑类数为1的有理数域二次扩域Qd~(1/2的代数整数环，利用范数为p或p~2的不可约元构造有限域，给出剩余类域的一组完全陪集代表元系，从而构造出一类有限域上的线性分组码，当错误取值于有限域乘法群的一个循环子群时，所得到的适用于二维信号的线性分组码可以纠单个错，推广了文[14-16]的结果。

我们首先在第四章讨论了紧量子群对应的乘法酉算子和紧量子群与离散群的交叉积对应乘法酉算子的关系，我们得到了在不同观点下的它们之间的关系式；同时给出了紧量子群〓对应的乘法酉算子和〓对应的乘法酉算子在具体的Hilbert空间上它们之间的表达式。

And it is proved that a semiring S in ■°■l is a subdirect product of a member of ■° and a member of ■l if and only if the multiplicative reduct of S is a subdirect product of a group and a semilattice by using the concept of sturdy frame of type(2,2) algebras.

Next we obtain some group theoretic conditions for the existence of p-blocks with defect 0 in some special groups, for instance, in an extension group of a nilpotent group by a abelian group, in a p-nilpotent group, in a group with all subgroups of order p are conjugate, and so on.

其次我们给出了一些特殊群的亏零块存在的群论条件，如幂零群被交换群扩张的群，p—幂零群，p—阶子群均共轭的群等。

Results EA group anaesthetize effect is slightly inferior than other two group,CSEA group and OCSEA group anaesthetize plane are more easy controlled than EA group,OCSEA group circulate is more stabilization than other two groups.

结果 硬膜外麻醉组的麻醉效果略差于另2组，CSEA组和OCSEA组的麻醉平面比EA组更易控制，OCSEA组的循环比其它2组更稳定。

Methods:All of 40 male Sprague-Dawley rats were divided into 3 groups:control group（group A, n = 10）, diabetic group for 4 weeks（group B, n = 14）, and diabetic group for 12 weeks（group C, n = 16）. The diabetes model was established by the injection of STZ. After some weeks erection function was examined by apomorphine injection. The content of NF-κB in the erectile tissue was evaluated by immunohistochemistry staining. At the same time the activity of NF-κB was detected by electrophoretic mobility shift assay.
