For lack of quantitative studies concerning the external force field effects on the spiral wave in oscillation reaction diffusion system
the solution of spiral wave in complex Ginzburg-Landau equation is simulated numerically with Runge-Kutta algorithm. For real uniform external vector field
it is found that the core of the spiral wave travels uniformly along the vector fieldwith its velocity equal to the strength of the vector field
and a vertical component about 4% of the parallel component exists. The simulation shows that the core of the spiral wave moves uniformly along a straightly line under constant imaginary vector field. The arms of the spiral wave become close along the vector field and vice versa
in which the deformation of the spiral wave increases with the enlarging strength of the vector field.
