原子干涉陀螺是基于冷原子物质波Sagnac效应测量相对于惯性参考系的转动角速度的一种陀螺仪,其转动时会在2条干涉传播路径之间额外产生相移,该转动相移中包含了垂直于拉曼光方向的纵向速度分量。一般认为入射原子团的纵向速度分布是导致原子陀螺干涉信号强度减弱和条纹对比度下降的最主要因素,但这忽略了与拉曼光方向平行的横向速度分布的影响。通过建立原子干涉陀螺的简单数学模型,定量分析2种分布对相同转速的影响程度,发现横向速度分布对最终干涉条纹质量非常关键,其比纵向速度分布容忍度更低。这要求在设计原子干涉陀螺系统时,需要更重视原子团的横向冷却效率,而不是只关注和转动相移相关的纵向速度分布部分。

A New Approach to Simulate Positional Error of Line Segment in GIS

引用

Geo-Spatial Information Science 2006年第2期9卷 142-146页

作者： ZHANG Lei deng min CHEN Xiaoyong Department of Remote Sensing and Geographic Information System Asian Institute of Technology Bangkok 12120 Thailand

To determine the distribution of positional error of a line segment, Monte Carlo approach is applied to simulate the probability density function of a line segment with the assumption that the error of endpoints in a line segment follows a two-dimensional normal distribution. For such purpose, a stochastic generator used for uncertain endpoints with the two-dimensional normal distribution is presented. This forms the basis of the generation of random line segment for the simulation of the error model of a whole line segment. The error models cover the cases where two endpoints are either independent or dependent to each other, also including a special case that the distance between two random endpoints in a line segment is close enough.

The Four Intersection-and-Difference Model for Line-Line Topological Relations

引用

Geo-Spatial Information Science 2007年第4期10卷 293-298页

作者： deng min LI Zhilin LI Guangqiang ZHANG Xuesong Department of Surveying and Geo-informatics Central South University Yuelu Mountain Changsha 410083. China

The description of line-line topological relations is still an unsolved issue although much effort has been done. The problem is involved in many practical applications such as spatial query, spatial analysis and cartographic generalization. To develop a sound and effective approach to describe line-line relations, it is first necessary to define the topology of an individual line, i.e., local topology. The concept of connective degree is used for the identification of topological differences in the geometric structure of a line. The general topological definition of a line is given, i.e., endpoints set and interior point set. This definition can be applied to the embedded spaces of different dimensions, whether co-dimension is equal to or larger than zero. On this basis, a generic model called the 4 intersection-and-difference is set up for the description of basic line-line topological relations, upon which a conceptual neighborhood graph is built with consideration of topological distance, it is concluded that the proposed model can represent the property of topological changes, and basic relations between line segments in IR^1 and IR^2.

关键词： topological relations line object topological distance conceptual neighborhood co-dimension
