                | In this paper, we studied the necessary condition for existence of the positive integer solutions of a class of generalized Ramanujan-Nagell equation. On the base of it, we gave all the positive integer solutions of a typical Ramanujan-Nagell equations, and generalized some results of reference [1] and [2]. |
