摘　　要：在CAT(0)空间中,构造了两个渐进拟非扩张非自映像的迭代算法,在适当的条件下证明了该算法强收敛到它们的公共不动点,所得结果改进了Sahin等人的研究结果.The algorithm for solving the common fixed point problem for two asymptotically quasi - nonexpansive non - self map-pings was studied in CAT（O） spaces. Under suitable conditions the strong convergence of the sequence was proved. The results extend and improve the corresponding results announced by Aynur Sabin etc.
