【Abstract】 In this paper a fourth-order rational difference equation is considered.The rule of the cycle length for the solutions of the equation is clearly described.Namely,the rule is 3~+,4~-,1~+,1~-,1~+,2~-,2~+,1~-in a period.And,the global asymptotical stability of positive equilibrium point of the equation is obtained.更多还原
