FCN

The complex eigen period period and Q value of the FCN are evaluated based on the resonance observed in the diurnal tidal gravity, the gravity change due to the polar motion is also studied.

Since 1987, some scientists in different countries have come to calculate the parameters of FCN by the observational data of gravity tide waves on the diurnal frequency band. They basically followed the Stacking Method, which needed five diurnal waves for the resolution.

1987年以来一些国家的学者相继开展了由潮汐资料解算FCN常数的研究，他们基本上都采用了5个周日波参与解算的迭积法（stacking method）。
