摘要：

The amplitudes of peaks in the angular power spectrum of anisotropies in the microwave background radiation depend on the mass content of the universe. The second peak should be prominent when cold dark matter is dominant but is depressed when baryons dominate. Recent microwave background data are consistent with a purely baryonic universe with Omega(m) = Omega(b) and Omega(A) approximate to 1.
