摘要：

The Zel'dovich-Sunyaev model-independent arguments for the existence of a neutral hydrogen phase is reviewed in light of new limits on the Compton y parameter from COBE. We conclude that with baryon densities compatible with standard cosmological nucleosynthesis, the universe could have remained fully ionized throughout its history without producing a detectable spectral distortion. We argue that it is unlikely that spectral observations of the cosmic microwave background will ever require the universe to have recombined for flat cosmologies.
