摘要：

We point out that the effect of reionization on the microwave anisotropy power spectrum is not necessarily negligible on the scales probed by COBE. It can lead to an upward shift of the COBE normalization by more than the 1 sigma error quoted, ignoring reionization. We provide a fitting function to incorporate reionization into the normalization of the matter power spectrum.
