摘要：
We discuss the hypothesis that a large (or even a major) fraction of dark matter in the Universe consists of primordial black holes (PBHs). PBHs may arise from adiabatic quantum fluctuations appearing during inflation. We demonstrate that the inflation potential V(cphi) leading to the formation of a great number of PBHs should have a feature of the plateau-type in some range cphi1<cphi<cphi2 of the inflation field cphi. The mass spectrum of PBHs for such a potential is calculated. © 1994 The American Physical Society.
