On that basis, the thesis pointed out the development trend of international commercial agency.

研究表明：尽管建立在区别论和等同论基础上的大陆法和普通法的代理概念及其表现形式之间虽存在着极大的差异，但这些差异首先只是学术性的，而且国际商业实践的发展在一定程度上已缩小了这种差异，两大法系关于代理的规定如同两大法系本身的发展一样，正在向着统一化的方向发展。

They include the fundamental concepts of jet bundle geometry needed in describing time-dependent mechanical systems, decomposition of jet bundles into a direct sum according to the constraints, horizontal distributions on constraint mainifolds, the global formulation of D'Alembert-Lagrange's equations and Chaplygin's equations, and nonholonomic mechanics on a Riemann-Cartan manifold. Meanwhile, the geometric significance of Chetaev's conditions and $\rd$-$\delta$ commutation relation are discussed in depth.

本文主要综述非完整约束系统几何动力学的外附型和内禀型Lagrange理论，包括非定常力学系统所需要的射丛几何学的基本概念、射丛按约束的直和分解、约束流形上的水平分布、 D'Alembert-Lagrange方程与Chaplygin方程的整体描述、以及Riemann-Cartan流形上的非完整力学，文中对Chetaev条件和d-δ交换关系的几何意义作了深入讨论。

Various methods such as the relationship of area, and the distance of the triangle to the centralness of three dots, the distance from the interior point, exterior point, the barycenter to the vertices of triangle, and the standard error and differences average obtained from three dots were determined with a dynamic geometry software GSP, and a statistic method was used to find a least error way to determine the centralness of three dots on a plane.

本研究是以平面上三点所构成的三角形之三顶点做讨论，分别以三角形的面积、周长，内心、外心和重心至三顶点距离，三点的标准差及平均差的概念，做为不同的判别方式，并以动态几何画板 GSP模拟不同的判断方法作为研究，再利用统计学上的方法，找出哪一种定义方式为最适合、误差最少的判断方法。

Through review historical cognitions on relations between complexity and randomicity, bring forth and analyzing immediate relationships between randomicity and Kolmogorov complexity from computer science, this paper tries to peel off some errors understanding on this relations and to return real relations about the them, and analyzing Gell Mann effective complexity concept, argument that two relations between complexity and randomicity, and three random instances.

本文通过对历史上复杂性与随机性关系的认识回顾，展示和分析了起源于计算机科学领域的Kolmogorov复杂性与随机性的直接关联，分析了盖尔曼的有效复杂性概念，论证了两种复杂性与随机性的关系，以及随机性的不同情况，力图剥离混合在复杂性与随机性相互关系上的一些误读和误解，还复杂性与随机性一种客观的本真关系。

Based on representative opinions about these questions which are raised by philosophers and logicians,the author thinks:1Truth and

作者分析了以往哲学家、逻辑学家对这些问题的一些代表性看法，认为：(1)&逻辑真&不是真的一个子类；(2)逻辑真只能测量观念形式上的关系；(3)逻辑真是认识论意义上的概念，它的本体论说明是一个&自足观念模式&的良性内循环结构。

Then it presents the basic concepts and the principles of GPS and the working principles of integrated container rubber-tired cranes. Based on the working principles of GPS.a technical plan of applying GPS into automatic control and the rubber-tired cranes is made up to study the practical application of GPS as well as the allocation of the related products.

接着，介绍了GPS的基本概念、原理和集装箱轮胎吊的工作原理，根据GPS系统工作原理设计了GPS系统在自动控制和轮胎吊上的应用技术方案；根据技术方案，研究GPS在轮胎吊上的实际应用及产品的配置。

The results of conversion show that the serious disc must be rejected because its reliable L-HCCF life is greatly less than an overhaul period. Finally, the load distribution of centrifugal and vibration force on labe is derived. Using two method, load on the crack labe gradually reducing and keeping constant with the crack propagation, a crack propagation analysis of fir-tree slot is carried out, and the calculating L-HCCF crack propagation life of slot on the unload method, which is nearly 3 times longer than that on constant method, is 20 times shorter than the pure low cycle life, and agree well with the experimental's.

最后，分析了离心力载荷和振动载荷在榫齿上的分布，进行了榫槽榫齿的有限元计算；提出了枞树型榫槽的卸载概念，并按带裂纹榫齿上的承载随裂纹增长而逐步减少和始终保持不变两种处理方法，进行了复合疲劳裂纹扩展及其寿命计算，由计算得出卸载下复合疲劳裂纹扩展寿命较单纯低周疲劳寿命下降二十多倍；按卸载处理的疲劳裂纹扩展寿命是按恒载处理的三倍多，前者与试验吻合，而后者则偏差较大。
