摘要
We prove that an Enriques surface S with certain configuration of half pencils is birationally equivalent to a normal quintic surface. No Enriques surfaces are known which do not satisfy this condition. We construct birational maps explicitly, and obtain the defining equations with ten parameters of the image in P3.
