摘要：

The cosmic microwave background radiation allows us to measure both the geometry and topology of the universe. It has been argued that the COBE-DMR data already rule out models that are multiply connected on scales smaller than the particle horizon. To the contrary, we find that many small universe models provide a good fit to the COBE-DMR data, provided that space is hyperbolic.
