摘　　要：本文引进了拟正规锥的概念，用它来确定Banach空间E的半序．在半序空间E中，给出了一些关于增算子和减算子的不动点定理，从而推广了文[1]、[2]、[3]中的某些结果．In this paper in order to define the partial older of Banach Space E,the author introduces the concept of quasi-normal cone in the space E.gives some fixed point the orems for increasing operator and descending operator,and thereby generalizes some results in papers by Guo Da inn and Sun Jinyun
