By means of the density matrixs in forms of Bloch equations which are coupled with Maxwell equations, we treated propagation effect of coherent pulse in the strong loss medium. Both pulse evolution and its influence on the medium have been studied. We observed the special transient coherent phenomena of pulse in the strong loss medium which include the stepwise decreasing of pulse area and periodic oscillation of number of spatial ionized particles.
