摘　　要：提出算子序压缩逼近和锥压缩逼近的概念.在没有连续性、紧性等条件下,讨论了u0-凹算子和一类混合单调算子的不动点问题,得到较为一般的结果.The concepts of ordered contractive approximation and the cone contractive approximation were introduced,and the fixed point problems on the u0-concave operator and the mixed monotome operator were discussed without the continuous condition and compactness condition,while some more general results were obtained.
