英文摘要	An S-dependent GFR method and a generalized conjugate gradient method are designed. Two estimated values of upper bounds for the ratio of beta(k) to beta(k)(FR) are given. The two convergence theorems are proved. The global convergent properties of s-dependent GFR method are obtained adopting several choice strategies of steplength and some results in recent literature are extended.
