宇宙大尺度结构的形成与星系形成密切相关。前者的研究把
星系基本上视为一质点，而星系形成研究涉及到其内部结构。宇宙大尺度
结构形成有两种模式，由小到大与由大到小。这两种模式被交替使用(当然不
是简单的重复)很重要的一个原因是星系形成研究的推动。
Formation of Galaxies and Large Scale Structures in the Universe

Abstract
The formation of the large-scale structures in the universe is closely related to that of
individual galaxies. Galaxies are essentially assumed to be a point mass in the study of the former
part and it is dealt with the internal structure in the latter study. There are two modes for the evolution of the
large-scale structures in the universe: small to large and large to small cosmogonies, which would be alternately, but progressively, adopted.
Every turn in the cosmogony adopted has been motivated by the study of galaxy formation.
Key words galaxies: formation--cosmogony: large scale structure of universe--cosmology: dark matter
