摘要 大天区面积多目标光纤光谱天文望远镜(LAMOST)将被建成,会产生大量的星系光谱数据。根据天文数据的积累过程,我们设计基于数据仓库的星系光谱分类系统。文章首先介绍了星系光谱的特征,数据仓库的特点,在此基础上描述了建立基于数据仓库的星系光谱自动分类系统的步骤,并给出对该系统进行测试的结果。 The Large Sky Area Multi-object Spectroscopic Telescope (LAMOST) will be completed, and will produce large amount of spectra of galaxies. According to the process of accumulation of astronomical data, we design a data warehouse based on the galaxy spectral classification system. In this paper, the feature of the galaxy spectra and character of data warehouse are described. Then the steps of designing the galaxy spectral classification system are shown. Finally, the result of testing the system is given.
