Let G be a finite group and Outcoz（G） the Coleman outer automorphism group of G（for the definition, see below）. The question whether Outcol（G） is a p′-group naturally arises from the study of the normalizer problem for integral group rings, where p is a prime. In this article, some sufficient conditions for OutCol（G） to be a p＇-group are obtained. Our results generalize some well-known theorems.

目的探讨吗啡预处理对大鼠脑缺血-再灌注损伤后神经元凋亡、Bel-2及Bax蛋白表达的影响。方法 Wistar大鼠32只随机分成假手术组、模型组、吗啡1mg·kg^(-1)组、吗啡7mg·kg^(-1)组,各8只。四动脉阻断法建立脑缺血模型。缺血前60min腹腔注射给药,假手术组和模型组给予生理盐水。脑缺血8min、再灌注24h后取大鼠的脑组织,HE染色观察海马区脑组织病理学改变、TUNEL法检测神经元凋亡、免疫组化法观察Bcl-2及Bax蛋白表达。结果吗啡预处理使海马神经元病理改变减轻、凋亡细胞数及Bax表达减少(P<0.01),而Bcl-2表达增加(P<0.01);且吗啡7mg·kg^(-1)组减少神经元凋亡及改善神经元病理变化的作用更为显著(P<0.01)。结论吗啡预处理可减少缺血-再灌注损伤后神经元凋亡,其作用机制可能与其影响Bcl-2和Bax蛋白表达有关。吗啡7mg·kg^(-1)预处理的保护作用更为显著。

The effect of diminishing marginal utility always has obvious influences in our daily life, which is also penetrate in the process of teaching. This paper clarifies the characteristics of the effect of diminishing marginal utility in teaching, also explains the reasons why the effect of diminishing marginal utility occurs in teaching. Then this study analyses the teaching performance with the influence of the effect of diminishing marginal utility. Finally, we give some suggestions to cope with the diminishing marginal utility in teaching.
