【Abstract】 The principle for construction of a kind of interpolation fractal surface and its iterate function formula are introduced. By applying the method of fractal interpolation, the problem of the stability on the fractal surface is discussed and some results are obtained. The results reveal that if the interpolation knots have small disturbs, so does the corresponding fractal interpolation surface. Thus the reliability of producing or simulating fracture surface by applying the fractal interpolation surface is ensured. The method offers theoretical basis for this kind of problem.更多还原
