We adopted the spectrum analysis method and the BAYTAP-G method to analyze the geoelectric potential data at the Niijima station during 1998~2000. After the quantitative analysis of the tide reaponse of geoelectric potential changes at the above station, we obtained some main characteristics of the tide response. Besides the tidal components with various periods such as diurnal tide, semi-diurnal tide, and so on, semimonthly and semi-yearly variations of tide response were also detected from the geoelectric potential data at the Niijima station.

According to the computational stability analysis conducted to the linear term time difference scheme in simple harmonic motion equation, one new semi-implicit integration scheme also is designed. By adopting a kind of revised time-explicitdifference scheme to these linear terms still included in spectral model governing equations, this defect of spectral model only partly used in semi-implicit integrating scheme, can be overcome to some degree.
