Investigating the normal structure of certain subgroups and computing their induced characters 某些子群的正则结构的研究及其诱导特征标的计算
It is an important problem that research the structure from character degree graphs 利用特征标维数图刻画群的结构是受到广泛关注的群表示论中的重要研究课题。
The theories of b - character and - partial characters were established by i . m . isaacs in 1984 Isaacs在1984年提出了-可分群的b _ -特征标和-部分特征标理论。
It is given that an another proof for the classical affine relative difference set by using gauss sums , and we construct a new family of divisible difference sets with parameters 给出了经典的仿射相对差集的一个特征标方法的证明。构造了一族新的可分差集，具有参数
This paper starts with the dynamic characteristics of structures , seeks the damage sign parameters ( dsp ) of composite materials structures , which have essential relations with the damage / healthy status 本文从复合材料结构的动力学特性入手，找出能较方便地反映结构损伤失效的特征标识量。
Then , the four procedures of controller synthesis , namely , the constraint transformation method ( ctm ) , the eigen marking method ( emm ) , the linear integer program method ( lip ) and the extended linear integer program method ( elip ) are discussed one by one 监控理论部分：首先讨论了禁止状态问题的最大允许控制器存在的充分必要条件；接着研究了四种具体的控制器综合方法，即约束变换法、特征标识法、线性整数规划法和扩展线性整数规划法。
Also , if x - , tnen [ xk , ] = 1 and x ( 1 ) / ( l ) = ( l ) / ( l ) . this paper consists of three parts : first , this paper gives an expansion for above famous theorem . among it characteristic condition of and separately being invariant in g and k weakens general and ordinary relationship : ik ( ) = ik ( ) - secondly , we have proved that when there exists b ( n ) and is a fong character associated with , the correspondence relationship automatically becomes the correspondent of b - character and fong character 本文首先给出isaacs上述著名对应定理的一个推广，把其中关于和分别为g -不变的和k -不变的特征标的条件减弱为更为一般和常见的惯性群关系i _ k ( ) = i _ k ( ) ，其次，我们证明了当为n的一个b _ -特征标而恰为一个与相伴的fong特征标时，相应的对应关系自动成为b _ -特征标和fong特征标的对应。
The ctm is suitable for the case that all e - type influentially uncontrollable subnets are state graphs , and the outstanding virtue is that the designed controller is explicit . the emm is suitable for the case that all f - type influentially uncontrollable subnets are normalized cascade petri nets , and the advantage is that control patterns can be on - line computed within polynomial times 约束变换法适用于所有e -型影响不可控子网为状态图这种特殊的场合，用该方法所综合的控制器最大的优点在于所董利达:浙江大学博士论文获得的控制器是显式的;特征标识法适用于所有凡型影响不可控子网为规范化序状petri网这种场合，用该方法设计的控制器在线运算工作量是多项式可解的。
In order to analytically deduce the characteristic scaling law , we have constructed a simplified piecewise linear model that describes the characteristic phenomenon so that we can quantitatively and analytically deduce the sudden change of the rules of the fractal dimension of the strange repeller and the averaged lifetime in the region occupied by the original attractor at a critical parameter value when the repeller disappears 为了解析地导出这种激变的特征标度律，我们构造了一个描述这种特征现象的简化分段线性模型，并借助它定量地解析描绘了当奇异排斥子在临界参数值消失时，奇异排斥子的分数维和在原混沌吸引子区域迭代的平均生存时间的突变。
