摘要
The main result of this paper is that when the coefficients of the time-dependent divergence form operators are Hlder continuous in time with order not too much smaller than （1/2）,the distance of the semigroups of two operators is bounded by the L<sub>2</sub> distance of the coefficients of their corresponding operators.
