This part of the thesis provides tools for doing non-commutative analysis in quantum physics.

在本文的第三部分我们用很多例子说明了超算符概念的重要性。

At last,it's proved that the equivalent class of sharp element is sharp element in the quotient algebra of a weak commutative pseudoeffect algebra gotten by normal Riesz ideals.

讨论了弱可换的伪效应代数商代数中可精确测量元与正规Riesz理想之间的关系。

It is proved that if R is a semi-commutative ring, the following conditions are equivalent:(1) R is a π-regular ring.

With a representation of the rotation group induced by the anti-commutative, self-inverse matrices the transformations named by Foldy-Wouthuysen, Cini-Taschek,Chakrabarti and the others are treated from a unified viewpoint. A new transforma-tion is found. Some applications of this method in the eigenvalue problems are demon-strated.

我们找出了由反易自逆矩阵荷载的转动群表示，统一地推广处理了Foldy-Wouthuysen，Cini-Tauschek，Chakrabarti等提出的各种变换；建立了一个几何图像，借助于它可以很容易地找到所要求的交换；举例说明了这方法在本征值问题中的应用。

With the help of its structure, this paper points out that the non-commutative finite solvable subsimple group will necessarily be a qualitative element group. And referring to the nature of qualitative element group, it can be easily identified the conditions that the ordered prime divisors in a solvable initial finite subsimple group should meet. Suppose that G is always a finite group.

利用其结构，指出了非交换可解有限次单群必为质元群，从而利用质元群的性质，可以很容易地初步确定了可解有限次单群的阶中素因子之间所必须满足的条件，主要得到下面的一些结论：定理1 G是非交换的可解有限次单群，则G′是G的唯一的非平凡正规子群，并且G′是初等交换p -群，此时| G |= p~n q，|G′|=p~n，。

The reporter is in Shanghai the discovery on the skill exchange platform of a website, the skill that the white-collar registers is multifarious: Spiccato, photograph makes guitar, all sorts of photography technology, languages, cooking, land belonging to one production unit but enclosed in that of another etc, look from commutative post, the person that exchange commonly decides study place in him home or tea lane.

记者在上海一家网站的技能交换平台上发现，白领登记的技能五花八门：吉他弹奏、照片制作、摄影技术、各种语言、烹饪、插花等，从交换帖上看，一般交换者都把学习地点定在自己家或者茶坊。

We also introduced the guage transformation, by this transformation, obtain the Lax equation and commutative family on the reduction space.

此外，还引入了规范变换，通过规范变换，就可以在约化相空间上得到Lax方程与对合系。

In chapter 3,we will consider the automorphisms of triangular matrix algebras over commutative semirings.

利用矩阵的一些性质，克服了环上可逆矩阵在半环中未必可逆的难点，证明交换半环R上的n阶三角矩阵代数Tn的自同构都是内自同构。

In quantum case,we ex-tend the Sklyanin's approach and find that unitarity condition of quantum R-matrix issufficient to construct commutative quantities with boundary,and its reflection equationsare obtained.

在量子情形下，我们把Sklyanin的构造方法扩充到一般的情形，即量子R矩阵只拥有幺正性条件。我们给出了此时守恒量的构造办法，及其相应的边界反射方程。
