Let $\Delta(x)$ and $E(x)$ be error terms of the sum of divisor function andthe mean square of the Riemann zeta function, respectively. In this paper theirfourth power moments for short intervals of Jutila's type are considered. Weget an asymptotic formula for $U$ in some range.

On the fourth power moment of $\Delta(x)$ and $E(x)$ in short intervals
