科学数据网格中面向天文应用的问题求解环境设计与实现

Design and Implementation of Problem Solving Environment for Astronomy Application Based on Science Data Grid

通过对虚拟天文台中科学课题的需求分析,提出一种基于数据网格针对天文应用的问题求解环境的框架;以“2MASS巡天星表搜寻OB星协候选体研究银河系的旋臂结构”科学课题为例,在科学数据网格上设计和实现了面向天文应用的问题求解环境,并对实现中的关键技术进行研究。

This paper proposed a framework of Problem Solving Environment （PSE） for astronomy application based on science data grid, after analyzing the requirement of science research in virtual observatory. It designed and implemented a material PSE on science data grid for the astronomic application of ＂Detect arm structure of the Milky Way through OB associations mining from 2MASS＂, researched key problems in the implementation.
