文摘In this paper the following results are got: 1. We prove that the order definition which is given by J.F. Trawb on the iterative function is wrong. 2. A existent theorem on the repulsive point is given. 3. We give some theorems to judge a fixed point of iterative function. They all improve the Ostrowski’s theorems.
