英文摘要： GuoShouJing Telescope (LAMOST) is one of large science projects of China, its pilot Survey has been carried out and the corresponding data has been released in stages. Based on the demands of LAMOST's spectral analysis, and by virtue of computer technology and methods,our purpose is to carry out the research of automatic processing of massive celestial spectra,including analysing the components of each galaxy sepctrum and its quality evaluation, and searching for rare celestial target candidates. we plan to utilize the theory and methods of pattern recognition and data mining to achieve the purposes such as automatic classification of galaxy spectra, the automatic measurement of the galaxy redshift ,spectral analysis of galaxy components and its evaluation, the search of the rare objects. The research topics include: 1. Analysing the spectral components of each galaxy spectrum from LAMOST, determining whether the received spectrum is the source spectrum and the composition of the entire galaxy; 2. constructing a Quality Evaluation System of galaxy spectra from LAMOST;3. researching on the feature extraction of galaxy spectra, improving old methods or propose new methods in classification of galaxy and redshift measurement;4. studying the real-time automated methods of searching for rare celestial objects(such
