摘　　要：本文主要研究了某类分形函数线性组合的分形维数。讨论了具有不同上、下Box维数分形函数线性组合的上、下Box维数估计,得到如下结果。一些情形下,线性组合函数具有与原函数相关的上Box维数或下Box维数。而其他情形下,线性组合函数的上、下Box维数数值均是不确定的。In the present paper, we mainly investigate the fractal dimensions of the linear combination of certain fractal functions. We discuss the estimation of Upper and Lower Box dimension of the linear combination of fractal functions having different Upper and Lower Box dimension, and have obtained the following results. In some cases, the linear combination function has Upper or Lower Box dimension that is related to the original function. In other cases, Upper and Lower Box dimen-sion of the linear combination function is uncertain.
