本文刻画了商群与集合的关系，给出了一个确定集合中那些与共轭的元素的方法，还证明了在线性情形下，商群与阶对称群是同构的，而且是与经典单形码的一个半直积，并且推关广了Calderbank等人的一个结果。

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。

Styles apically broadened and 2-cleft or emarginate; drupes globose to ellipsoid, apex and base rounded to obtuse; stipules ovate-lanceolate to ovate, enfolding naked terminal bud; leaf blade base symmetric or weakly asymmetric.

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.

本试验研究结果表明：60 Coγ射线辐照小豆种子的半致死剂量平均为 3 89Gy ，且M1生长初期叶片性状有明显的叶面缺刻、叶色缺绿、叶形不对称、叶缘卷曲、花叶、黄叶等致变现象，各种畸型叶出现频率与辐照剂量大小有关；M1根尖细胞中有多种染色体畸变类型，以染色体桥和断片频率较高，辐照剂量在 40 0Gy以上时根尖细胞异常率达 1 0 %以上；植株花粉育性与辐照剂量呈极显著负相关，京农 2号植株花粉育性达 5 0 %时的辐照剂量为 3 78Gy。

Its shell is divided into two parts. Its cranium is like a half helmet. There are things like the eyes in the front of its shell, 6 pairs of airholes and hard teeth of double layers in two sides of its back. There are the thin, sharp and hard thorns on its shell. Its tail is triangular, which can move about.

其壳分为两部分，头盖形似半只钢盔，壳背前端有眼状物，两侧对称分布气孔6对；背甲布细尖硬刺，边有双层细长硬齿；尾呈三棱形整体，根部可动。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
