Owing to the importance of Disquisitiones Arithmeticae in histoiy of number theory and the core position of the congruent theory in elementary number theory, this paper is to focus on the following two topics: the origin and development of Fermats little theorem and the quadratic reciprocity law which was hailed as golden by Gauss.

鉴于《算术研究》在数论发展史上的重要性以及同余理论在初等数论中的核心地位，本文重点研究费马小定理和被高斯誉为"黄金定律"的二次互反律的起源和发展。

In this method, first, the gray-scale image of the molten pool is obtained according to the fractal-based discrete Brown random field theory. Next, the connected domain is detected based on the binary morphology theory and is then used to remove the noise and obtain the target image. Moreover, the successive edges of the image are obtained by means of the Open-Close operation on the basis of the mathematical morphology theory.

In this dissertation,Von Numann and Morgenstern Axioms are analyzedagain at first.It is pointed out not only that preference relations are often latticeordered,but also that the transitivity axiom,along with the independence axiomand the continuity axiom is still rational to a high degree,then a new set ofaxioms for lattice-order decision-making behavior is established.At last,relatedsubjects based on lattice in preference theory,utility theory,decision-makingmethods,multiattribute decision-making,and group decision-making are studied.In this way,the lattice-order decision-making theory is framed.Main creativeresults are obtained as follows

本论文重新审视了Von Neumann-Morgenstern理性行为公理体系，对以前学者较少涉及到的连通性公理提出了质疑，指出偏好关系具有格特征，而传递性公理、独立性公理以及连续性公理在很大程度上仍具有合理性，进而创建了格序决策行为公理体系，研究了基于格的偏好理论、效用理论、决策方法、多目标决策以及群决策中的相关问题，初步构建了格序决策理论框架，主要研究成果如下

This text is exactly the route that attempts to explain the system changes of family firm in terms of theory of the modern agreement, utilize a series of mathematics models to strengthen the convincingness of the theory, thus achieve the goal of analyzing. After analyzing the agreement nature of the family firm. Drove through theory identification and mathematics and physics

在分析了家族企业的契约性质后，重点通过理论证明以及数理模型说明家族企业作为一个不完全契约需要建立一种有外部人力资本参与的新的企业契约，更进一步的分析引入外部人力资本后家族企业契约性质的变化及由此导致的家族企业发展的新困境，并提出建立一般性关系型激励契约以及报酬契约是克服家族企业发展障碍的现实有效选择。

It can be carried out form the following aspects: Firstly, the direction of innovative achievements of theory must quote copiously from many sources and be deepened constantly. Secondly, the content of innovative achievements of theory must keep pace with the times and accord with the needs. Thirdly, the methods of innovative achievements of theory must combine with reality and pursue the effectiveness.

思想政治工作的理论创新可以从以下三方面进行：一是从理论创新成果的方向上必须旁征博引，不断深化；二是从理论创新成果的内容上必须与时俱进，符合需要；三是从应用理论创新成果的方法上必须结合实际，讲求实效。

This paper founds a bidding strategys frame based on the game theory. This paper combines the game theory and the principal-agent theory and expounds the cost-plus based on the bidding and the bidding based on the contract.

本文建立了一个基于博弈论的招投标机制设计的研究框架，从而为招投标机制设计提供了一个规范的分析思路；另外本文还将完全信息动态博弈与委托—代理理论结合起来，开创性的提出了基于招投标机制的最优成本补偿合同和基于合同的招投标模型，不仅可以包括线性合同的激励，而且还能解决基于博弈论的非线性激励合同问题；在提出的相似标的概念基础之上，本文还综合了相关模型，针对相似标的的特点，给出了几个相似标的的招投标模型。

This article from the international criminal law of view, discussed several problems of specific application about theory of Substantially similar principle double Criminality in the process of extraditing international criminal offenders, considered that the theory didn't violate nullum crimen nulla poena sine lege or principle of the political offense exception to extradition and believed that this theory can conhere with the principle of aut dedere aut judicare, which is extended from the principle of universal jurisdiction.

本文从国际刑法学的角度，论述了在对国际犯罪进行引渡的过程中，双重犯罪原则之实质类似说的具体适用需要把握的若干问题，认为实质类似说与罪刑法定主义并无冲突，也不会造成对政治犯不引渡原则的背反，它与普遍管理原则所引申出的或引渡或起诉原则能够达成协调。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
