Taking into account the large number of information contained in authoritative journal about the History of Science, while avoiding the unreliability of results concluded by a single journal, through analyzing the contents metrically from 1993 to 2005 in three most authoritative journals on History of Science (ISIS, History of Science , British Journal for the History of Science), the paper displayed detailedly the microcosmic orbits of History of Science, revealed the hot points and hold the trends from the macrocosm and provided evidence and theoretical support for Historiography of Science. This will undoubtedly have an important academic value and theoretical significance.This article has three parts.

考虑到权威期刊所蕴涵的大量的科学史信息，同时避免单一期刊研究结论的不可靠性，本文选取国际上最权威的三份科学史综合期刊《爱西斯》、《科学史》、《英国科学史杂志》(British Journal for the History of Science)，对1993-2005年的内容进行计量分析，详细地展示这十多年来科学史研究的微观发展过程，并在三者计量结果进行相互比较印证的基础上，揭示科学史研究热点及发展脉络，从宏观上把握科学史研究的学术走向，对科学史研究重点的调整提供证明与借鉴，并为科学编史学的研究提供理论支持。

As one part of the project, the dissertation is developed with thelocalization problem in mobile robot navigation. Combined with "MobileRobot 1 of Central South university (MORCS-1)", a mobile robot designed byus that equipped with a 2D laser measurement system to sense the environmentand the proprioceptive sensors such as the odometry, gyroscope to calculate itsdead reckoning, the approach about the four kind uncertainty factors of mobilerobot localization is studied. These researches include that the error analysisand calibration of position sensors is implemented to reduce the measurementnoise, the 3D kinematic model of mobile robot is built to gain the accuratepose in complex terrain, some work on the automatic detection of static ordynamic obstacles based on laser scanner is investigated to eliminate thedynamic influence of the environment and to realize the reliably absoluteposition, and lastly a robust algorithm is presented to involve the incrementalenvironment mapping and self-localization of mobile robot with unknown dataassociation and to improve the self-localization performance of mobile robotunder unknown environment.

作为该项目研究的一部分，本论文以移动机器人导航中的定位问题为研究内容，利用自行研制的装配有二维激光雷达环境感知系统，并通过里程计、陀螺仪等内部传感器来实现航迹推测的移动机器人"中南移动1号MORCS-1"，重点围绕影响移动机器人系统定位的四类不确定性处理展开研究：通过移动机器人定位传感器的误差分析及校准，旨在消除传感器噪声所带来的测量误差；通过建立移动机器人的三维运动学模型进行航迹推测，以期实现复杂地形下精确的移动机器人本体姿态感受；通过基于激光雷达的动静态障碍的自主检测等相关研究，尽量消除环境的不确定因素影响进而实现可靠的移动机器人绝对定位；通过以上研究，针对未知数据关联下移动机器人增量式环境建图与自定位的研究提出一种鲁棒的滤波算法，改善未知环境中移动机器人自定位的性能。
