摘      要：this paper we discuss polynomial Lienard’s equatiou where N is a positive integer number. For N=2n+1 and N=2n+2, in § 2 we give some sufficient conditions -guaranteeing system (P) to have at least (or exactly for N=2n+1 )n limit cycles. In §3,we give the programing profile diagram analysed by computey, which can estimate the existence of n limit cycles and construct n limit cycles. In § 4 we give a few concrete examples.
