But these methods limited by the expense of computing fundamental matrices and trifocal tensors or of the nonlinear optimization involved in computing epipolar tangencies. Through the studies of the invariants of the single axis motions, computational theories have been developed in this thesis to provide practical solutions for the problem of structure and motion from fitting the corresponding points in the whole sequence to its conic locus or conics for short.

在最近的研究中，一些研究人员利用视觉几何的方法从非定标的图象中对单轴旋转运动进行分析，提出了利用基本矩阵和三焦距张量求解单轴旋转运动中的关键参数——旋转角度的算法，但是该算法需要计算一系列相邻2图象的基本矩阵和一系列相邻3图象的三焦距张量，由于每个基本矩阵的自由度为7，每个三焦距张量的自由度为18，导致算法参数数量非常之大。

Different from the case of strict minimal siphons in a net system, the number of elementary ones is bounded by the smaller of place count and transition count. Based on the ideas mentioned above, this thesis proves that the set of elementary siphons is not unique, while different ones may lead to different control results.

本文在此研究的基础上，论证了网系统中的基本信标的不唯一性，控制不同的基本信标可以得到不同的控制效果，进而提出了最优基本信标的概念并给出了相应的计算方法，应用这一计算方法可以在多项式时间内求得一组最优基本信标，也就是说，控制该组基本信标相对于其他的基本信标可以使得系统Petri网模型具有最多的可达状态，这在实际中，意味着系统具有更大的灵活性。

The paper induces and analyzes research method of the tooth, including Method line of the tooth theory,Envlopment theory, Camus theory, Circling cluster theory and so on.Based on the past theories,the new measure to deduce the chain wheel tooth equation of roller chain at high speed,Circling cluster and envlopment theory,is proposed by analyzing basic concept of equidistant curve and Willis theory.Following the presentation of drawing lessons from traditional roller chainof the change of stanza line distance. A new type of roller chain at high speed is given in the paper.The paper studies deeply structural characteristics, the change of stanza line distance,separation between plank and bore and so on.According to design requst of roller chain at high speed and the study ofH_y--V_0 tooth chain,the impossibility that Quasi-conjugage engagement theory isrealized by the engagement of roller chain at high speed from the aspect of theory is decribed.

Based on the comprehensive researchof fundamental geopolitical theories,the dissertation reveals a dichonomic structure--the most important content and characteristic of geopolitics——influenceinternational relations with some disciplines by special modes;fourthly,with the logicof dichonomy,the dissertation analyses and researches the geopolitical position andstrategies of China,as one of the most important powers in the Rimland.

地缘政治学的基本理论不过对此作出了理论上的反馈；4、以二分论的理论逻辑，分析和研究了作为边缘地带最重要的大国之一、而又必须处理好海陆关系的中国的地缘政治地位和地缘政治战略，提出了要从地缘位置的一分为二到地缘选择的合二而一，对中国的地缘战略进行新的定位。应该指出的是，虽然本文追述了西方地缘政治学的一些基本理论和观点，但是本文的基本概念、主要观点、研究角度、逻辑论证和最后结论都是作者本人提出的。

Therefore, a nation needs to establish a matured human rights protection mechanism as soon as possible to ensure that the emergency powers can protect its fellow citizen's fundermental rights fully and effectively when an energency situation occurred, without abusing the administrative discretion. This paper discusses how to protect citizen's basic rights and how to improve the protection system in China in the state of emergency. The paper is divided into four parts: The introduction section describes how natural and man-made instability factors frequently caused emergent situations in the world, and how the nations objectively infringed upon citizen's basic rights in response to the crises. Then it introduces the central theme of discussion in this paper.
