In this dissertation, a theorem to describe the relationship between the quotient group Aut/H and the set F_f is presented. And a way to find the elements of F_f that are conjugate to f is proposed. Then we prove that the quotient group Aut/H is isomorphic to S_3, the symmetric group of order 3, and H is a semidirect product group of GL_(m/2)(4) with the classical binary simplex code S_m in the linear case.
本文刻画了商群Aut/H与集合F_f的关系,给出了一个确定集合F_f中那些与f共轭的元素的方法,还证明了在线性情形下,商群Aut/H与3阶对称群S_3是同构的,而且H是GL_(m/2)(4)与经典单形码S_m的一个半直积,并且推关广了Calderbank等人的一个结果。

On the basis, three equivalent statements are obtained. Let S be a semigroup with left central idempotents, then (1) S is a quasi-right semigroup;(2) S is a quasi-completely regular, and RegS is an ideal;(3) S is a nil-extension of strong semilattice of right semigroup.
在此基础上得到了3个等价命题:若S为具有左中心幂等元半群,则(1) S为拟右半群;(2) S为拟完全正则的,RegS为S的理想;(3) S为右群强半格的诣零理想扩张。

Finally, as a generalization of the group-graded regular ring, the notion of group-graded weakly regular ring is introduced and we discuss it in a new way. In particular, an equivalent condition for the semigroup rings to be weakly regular(T-weakly regular) is given.
将群分次正则环推广到群分次弱正则环;用新的方法研究了环的弱正则性,并得到半群环的弱正则性和T-弱正则性的一个等价刻画。

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.
在设计变化地块识别的判决函数时,本文针对变化地块识别工作的特殊性:1、以无规律性、无集群性的变更地块为研究对象;2、以降低变更地块的漏判率为目标,对距离判别法做了如下改良:1、将无规律、无集群性的变更地块识别问题转化为有规律、有集群性的地类识别问题;2、严格判类规则(将落入误判高发区的待测样本视为变更地块),以减少变更地块的漏判。

Supracrustal sequences free of early strong deformation The early deformation of Jingangku formation complex of Hengshan Wutai group complex has formed a bedding parallel S〓 gneissic and schistosity, occasionally bedding parallel recumbent folds in layers. The early deformation of the near-horizontal ductile shearing isn't very strong in Wutai group complex. The orientation of shear movement is NNW—SSE.
