In this paper, a difference Leslie’s prey and preyed system is as follows:x t+1 -x t=x t(R-x t-αy t), y t+1 -y t=y t(r-y tx t), where R>0, r>0, α>0, are constants, a condition of periodic solution with n-vector function is given.

给出了Leslie’s捕食与被捕食离散型系统 xt+ 1-xt=xt(R -xt-αyt) ,yt+ 1- yt=yt(r - yt/xt) ,具有n周期向量函数的周期解的条件 (其中R ,r ,α均为正参数 )。
