In this paper, on the basis of a single-particle model, the relationship between spontaneous radiation and stimulated radiation in Cerenkov free electron lasers is obtained. The results show that in Cerenkov free electron lasers there is a relationship similar to Madey Theorem in wiggler free electron lasers. The gain calculation of oblique angle stimulated Cerenkov radiation by making use of this relationship is given.
