Finally, the corrections of the effect of oceanic tides on the gravity tidal observations in Beijing, Lanzhou and Lasa were calculated.

Later, it is proved that this software, when combined with digital acquisition system, has greatly raised the whole values of gravity solid tidal observations.

The influences of ocean tide load on the observations of Earth's gravity tides at part of the seismic network stations are estimated by means of discrete integral using the latest ocean models.
