摘要
<正> In this paper, we study the cosmic density wave(C. D. Wave) according to gravita-tional instability in the expanding universe. Analysing the variations of the Jeans mass MJcaused by the evolution of the universe. we obtain the preferred C. D. Wave just before re-combination, i.e.,those with the characteristic mass M near to MJ(T=Tr). and the relationwhich can be used to determine the wavelength of the wave. The result suggests that a seriesof maxima should appear in the Z-distribution of the objects which had been formed in thebackground with the C. D. Wave, and that the condition obtained can be used to calculatethe redshift value corresponding to each maximum. For a specific cosmic model:Tro=2.7 K, H_o=80km.sec-1.Mpe-1and ρ_o=ρHo=3.5×10-31g.cin-3,the wavelength of the preferred C. D. Wave is estimated to be about0.516 Mpc just before the recombination. The redshift value corresponding to each maximumin the Z-distribution of the quasars can be calculated by formula In(1+Z)=0.205n+B,where n is integer. It is expected that a maximum value in the range of 0.05 更多 还原 AbstractFilter('ChDivSummary', 'ChDivSummaryMore', 'ChDivSummaryReset');
