Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。

Taking Abstract traditional Chinese house number plate system , it is not difficult to discover that Nanjing national government absorbed a large number of elements and structures from the house number plate system in history .

纵观传统中国门牌制度，不难发现，南京国民政府时期的门牌制度大量吸收了历史上多个时期门牌制度的相关要素和结构形式，并结合新的时代条件形成了自身的特有样式和确定内涵。

The results indicated that soil bacterial number decreased significantly (P.01), and soil fungi number also decreased (P.05), but not as significant as the decrease of bacterial number. The amount of soil actinomycosis decreased (P.05) under elevated CO2 in the non-rhizosphere soil of P.

结果表明：高浓度CO2（700μmolmol^(-1)和500μmolmol^(-1)）处理对长白赤松和红松幼苗非根际土壤细菌数量具有显著的(p.01)抑制作用，对真菌数量亦有抑制作用。

In addition each record has a field for phone number, fax number, cell phone number, e-mail address, web site and there is even a field for notes that can store information such as clothes sizes, favorite colors, etc. you name it.

In this master thesis, we mainly discuss the adjacent vertex- distinguishing total chromatic numbers of some special graphs and prove that Zhang"s conjecture holds for these graphs. Then we get the adjacent vertex-distinguishing total chromatic numbers of the Halin Graphs. Moreover, we investigate the Generalized Petersen Graphs, prove that some classes of positive integers can"t structure the Generalized Petersen Graphs and get the result that the adjacent vertex-distinguishing total chromatic number is 5. Finally, based on the number and the parity of circles contained by the graph, we get the adjacent vertex-distinguishing total chromatic number of two classes of graphs.

本学位论文首先主要针对几个特殊图类讨论其邻点可区别全色数，验证了其满足图的邻点可区别全色数的猜想；再证明了非轮的Halin图的邻点可区别全色数；接着研究的是广义Petersen图，讨论了不能构成广义Petersen图的几类正整数，并证明了该图的邻点可区别全色数等于5；最后，根据图所含圈的个数及其奇偶性得到了两类图的邻点可区别全色数。

Although most antibiotics reduced the number of bacteria in pancreas, they affected the balance of intestinal microflora. The QYT herbs could decrease the number of intestinal aerobe, increase the number of bifidobacteria and lactobacillus, and significantly reduce bacterial translocation rate.

绝大多数抗生素虽然能减少胰腺细菌数量，但却影响微生态平衡，而清胰汤能明显减少肠道需氧菌数量，增加双岐杆菌和乳酸杆菌数量，降低细菌的移位率。

It is rich in content, and algebraic number theory, geometry number theory, number theory, etc. have set more closely linked .

不定方程的内容十分丰富，与代数数论、几何数论、集合数论等等都有较为密切的联系。

Main work follows:(1) In the first part of this paper, a historical development of the number theory before Gauss is reviewed.Based on the systematic analysis of Gauss"s work in science and mathematics, inquiry into the mathematical background that Disquisitiones Arithmeticae appeals and Gauss"s congruent theory;(2) The development process of Fermat"s little theorem and its important function in the compositeness test is elaborated through original literature.we think that the first three section of Disquisitiones Arithmeticae is a summary and development for ancestors" work about Fermat"s little theorem,show that Fermat"s little theorem played an important role in the elementary number theory;(3) With the two main sources of the quadratic reciprocity law, investigating Fermat,Euler,Lagrange,Legendre, until the related work of Gauss,the way to realize the laws huge push to the development of algebraic number theory in 19 centuries.

本文主要做了以下工作：(1)首先回顾了高斯之前的数论研究状况，在系统分析高斯的科学与数学成就的基础上，探讨了《算术研究》出现的数学背景和高斯的同余理论；(2)通过对原始文献的系统解读，深入分析了费马小定理发现发展的历程以及在素性检验中的重要作用，指出《算术研究》前三节是高斯在总结并发展了前人对该定理研究的基础上形成的，并揭示了费马小定理在初等数论定理证明中的核心地位；(3)以二次互反律的两个主要来源为线索，详细考察了费马，欧拉，拉格朗目，勒让德，直到高斯的相关工作，揭示了该定律对十九世纪数论发展的巨大推动作用。
