| Abstract: | With the 1-d wave motion equation , this paper analyzed the causes of frequency-dispersion and low resolution in synthetic seismogram, defined the difference operators, Dzz and Dtt, decided the nondispersion condition: Dtt/Dzz=c2, and suggested a method to increase the resolution in synthetic seismogram. |

| Keywords: | frequency-dispersion resolution difference operators |
