Thus , it can be clearly recognized that the global continents located at near equator and southern hemisphere , showed the characteristics of range along latitude ; chinese continental blocks still located among the laurentia , siberia and gondwana in paleozoic ; following the fast moving of siberia plate to northwards , the amalgamation in north - south direction at the western parts of laurentia and gondwana , subducted the lapetus and rheic oceans , until to form the uniform pangea in the late stage of paleozoic ; however australia and india plates in eastern gondwana move and disperse gradually to southwards , to extend crust and form the paleo - tethys ocean ; the chinese continental blocks and adjacent blocks still located in paleo - tethys ocean , preserved the status of dispersion , gradually moving to northwards , showed the characteristics of range along north - south orientation , until carboniferous and triassic a series of local collisions happened in tianshan - hing ' anling , kunlun , qinling - dabie , jingshajiang and shaoxing - shiwandashan zones , thus the most part of chinese continental blocks amalgamated to eurasia continent 由此可以清晰地看出，在古生代早期全球各大陆的主要部分都位于赤道附近及南半球，大致表现为沿纬度、呈东西向排列的特征，中国及邻区的小陆块群在古生代始终都处在劳伦大陆、西伯利亚与冈瓦纳大陆之间；随着西伯利亚大陆的快速北移，在劳伦大陆与冈瓦纳大陆的西部地区发生南北向拼合，亚皮特斯洋和里克洋的消亡，到古生代晚期形成统一的泛大陆；而冈瓦纳大陆的东部（澳大利亚和印度等）则逐渐向南移动、离散，地壳张开，构成古特提斯洋；中国及邻区的小陆块群则一直处在古特提斯洋中，保持离散状态，总体上缓慢地向北运移，并逐渐转为近南北向的排列方式，石炭纪到三叠纪才在天山兴安岭、昆仑山、秦岭大别、金沙江和绍兴十万大山等地段发生一系列局部性的陆陆碰撞，使中国大陆地块的大部分逐渐并入欧亚大陆。
In this part , the author mainly introduces the theory of the image moment invariants and its current application , analyses the influence of scale factor on moment invariants features under the state of discrete and adopts a sort of modified algorithm to abstract the eigenvector of the objects " outline finally , the author uses bp network to classify the mode 该部分主要论述了图像不变矩的原理和应用现状，分析了在离散状态下比例因子对7个不变矩的影响，提出了一种的改进算法，并利用其提取了物体外形轮廓的特征向量，最后用bp网络进行了模式分类。
At present , there are many achievements of risk analysis and decision - making of huge investment projects , but there are no generally recognized standardization model . combining the project , this paper tries to establish an applied standardization model and make it be applied to the project . and according to character of management of information system , it also underlines development of computer program 在本论文中，首先介绍了敏感性分析，同时结合实际项目，对敏感性分析的优缺点进行了探讨。风险分析是本论文的重点，在对风险因素进行辨识和估计后，共提出三种方法，即离散状态组合法、统计解析法和蒙特卡洛法。
A real options framework of venture capital investment decision in discrete - time is build . based on the extended npv formula , binomial model combined with black - scholes formula , an integrated model of venture capital investment decision evaluation is given . there are five parts in the model , and five steps to get the solution to 构建了离散状态下风险投资决策的实物期权框架：以扩展的净现值法计算公式为基础，将二叉树模型与black - scholes模型结合，构建了一个评价评价风险投资决策的综合模型，模型分为五部分，分五步求解。
In basic action layer ' s designing , it uses a fuzzy - pid control algorithm that brings the system with a good dynamic and static performance . in the whole decision - making process , the protean situation on the competition ground is expressed by an artificial intelligence method for describing the state space that is constituted by selecting a small number of discrete representative states . desired actions are set for every robot based on the tasks of the system and the strategy 其中在进行基本动作层的设计时，采用了模糊控制与pid控制相结合的智能控制算法，使系统具有良好的动、静态品质；而在进行整体决策时，采用了人工智能的状态空间表示方法，在比赛场上瞬息万变的态势中选择少量的具有代表性的离散状态来构成状态空间，再根据系统需要完成的任务，为机器人确定有限的动作集合，并通过决策推理，给每个机器人选择合适的动作，从而决策得出机器人的左右轮转速值，实现对系统的实时控制。
