  We have studied the scalar perturbation of static charged dilaton black holes
in 3+1 dimensions. The black hole considered here is a solution to the
low-energy string theory in 3+1 dimensions. The quasinormal modes for the
scalar perturbations are calculated using the third order WKB method. The
dilaton coupling constant has a considerable effect on the values of quasi
normal modes. It is also observed that there is a linear relation between the
quasi normal modes and the temperature for large black holes.
