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.

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.
