In this paper,we are concerned with the stochastic averaging for stochastic differential equations(SDEs) with non-Lipschitz coefficients driven by fractional Brownian motion(fBm)of the Hurst parameter H ∈(1/2,1).We define the stochastic integrals with respect to the fBm in the integral formulation of the SDEs as pathwise integrals and we adopt the non-Lipschitz condition proposed by Taniguchi(1992) which is a much weaker condition with wider range of *** approximate SDEs are *** then use their corresponding solutions to approximate the solutions of the original SDEs both in the sense of mean square and of *** can find the new points for those non-Lipschitz SDEs with fBm,and the similar asymptotic results are discussed under different types of stochastic integrals.
