中文摘要：

对R^3中的仿射迭代函数系进行扰动，得到了一类带扰动项的迭代函数系，它的吸引子是一个二元分形插值函数的图象，研究这类分形插值函数及其矩量的扰动误差问题，给出了相应的误差估计式。

英文摘要：

This paper is concerned with a kind of iterated function systems （IFSs） in R^3 with perturbation terms whose attractor is the graph of a bivariate fractal interpolation function （FIF）. The problems of perturbation errors of such FIF and its moment are studied. The results about error analysis are obtained.
