英文摘要	We investigate the growth of the large-scale structure in the superfluid Chaplygin gas (SCG) model. Both linear and nonlinear growth, such as sigma(8) and the skewness S-3, are discussed. We find the growth factor of SCG reduces to the Einstein-de Sitter case at early times while it differs from the cosmological constant model (ACDM) case in the large a limit. We also find there will be more stricture growth on large scales in the SCG scenario than in ACDM and the variations of sigma 8 and S-3 between SCG and ACDM cannot be discriminated.
