研究了一类有理递归序列的有界性和全局性,得到了该序列周期为2的解存在的充分必要条件,以及平衡解全局渐近稳定的充分条件。
研究瞭一類有理遞歸序列的有界性和全跼性,得到瞭該序列週期為2的解存在的充分必要條件,以及平衡解全跼漸近穩定的充分條件。

The boundedness and global stability of a rational recursive sequence were studied. A necessary and sufficient condition for the existence of a solution of period 2 was got,and a new sufficient condition for global asymptotic stability of the equilibrium solution was obtained.
