摘要：

We have estimated the power spectra of density fluctuations produced by cosmic strings with neutrino hot dark matter (HDM). Normalizing at 8h-1 Mpc [where h = H-0/(100 km/secMpc), and H-0 is the Hubble constant] we find that the spectrum has more power on small (less than or similar to 10h-1 Mpc) scales than HDM + inflation, less than cold dark matter (CDM) + inflation, and significantly less the CDM + strings. With HDM, large wakes (approximately 20h-2 Mpc) give significant contribution to the power on the galaxy scale and may give rise to large sheets of galaxies.
