For a finite group G, a subgroup H is called c-normal in G if there is a normal subgroup K such that G=HK and H∩K≤H, the largest normal subgroup of G contained in H. c-normality was replaced by c-π-quasinormality or c-sub-normality. The following were showed equivalent. First, there is a solvable maximal subgroup M such that M is c-π-quasi-normal in G.

推广了有限群中的c-正规性概念，引入了c-次正规性和c-π-拟正规性概念，并利用新概念给出了有限群可解的几个条件，证明了：设G是有限群，那么，下述条件是等价的：G有一个极大子群M在G中是c-π-拟正规的而且是可解的。

China"s banking industry will soon be completely open, which will make it inevitable for our country"s banking industry being pounded by foreign banks. M Bank has undergone quite a few years of development and carried out the shareholding system reform. However, each staff member of M Bank H Branch has to sober-mindedly realize that, when compared with others in the same business and same department, such problems as the poor comprehensive quality of some of our staff members and the low per capita efficiency have become the "bottleneck" of our further development.

银行业即将全方位放开，使我国银行业所受到的外资银行的冲击不可避免。M银行经过了多年发展，虽然进行了有效的股份制改革，但作为M银行H支行的每一位员工必须清醒地认识到，与同业相比，诸如部分人员综合素质低、人均效益偏低等问题已经成为我们进一步发展的&瓶颈&。

A Schottky precise mass spectroscope in light-medium and in heavier nuclei with the mass resolution of △m/m=5×10^(-6) or 5×10^(-7), respectively, has been successfully built up and operated well at ESR (Experimental Storage Ring cooled by electron beam) in GSI, the leading nuclear research institute.

肖特基精密质量谱仪，是建立在GSI所电子冷却存储环上的精密质量谱仪，它对轻中量核与重核的测量精度△m/m分别达到5×10^(-6)，和5×10^(-7)。

First, we deduce a formula for vacuum polarization pressure as f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 , based on the isotropy of distribution of neutrinos ν0 in the lowest energy state in the physical vacuum, requested by the Pauli exclusion principle. Then, we deduced the metric equation of the general relativity and the equivalence principle according to this formula. Further, we demonstrate that this vacuum polarization pressure is the gravitation in general meaning.

首先从泡利不相容原理要求的在物理真空中最低能态中微子ν0分布的均匀各向同性出发，推导出真空极化压力公式 f ＝ G m M （ r ∕ r ＋ v ∕ c ）∕ r 2 ，然后由此公式推导出广义相对论的度规方程和等效原理，并论证此弱作用力的真空极化压力就是通常意义下的引力。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
