摘要
Based on the data of CfA redshift survey, the spatial 2-point correlation function ofgalaxies with different luminosities has been analysed and the results have been comparedwith those in literature. It is found that galaxies with different luminosities have obvious dif-ferences in their large-scale distribution. Although all the correlation functions can be appro-ximated by the power law, the absolute values of the power indices, clustering strength andclustering scales increase with the luminosity of galaxies. Further investigation of the large-scale distribution of galaxies with different luminosities will set new constraints on the dis-tribution of matter in the universe and the origin and evolution of galaxies.
