计算了日本海的M2，S2，K1和O1等4个主潮波对东亚9个VLBI站的负荷位移参数和重力改正。得到日本VLBI站的径向和水平方向的位移量分别为3～12mm和1～3mm，上海VLBI1站和韩国的Daejeon站相应的径向量分别为1mm和3～4mm。估计了上海至日本鹿岛和水站的负荷基线变化分别可达±7．6mm和±28.4mm。此外，日本的水、野边山、鹿儿岛和Usuda站的负荷重力变化分别可达0．8～0．9μGal，它接近于目前绝对重力测定的观测精度（±μGal）。计算还表明，不同地球模型的计算负荷位移之差在目前测地学精度水平下可以忽略。
The load-displacement parameters and gravity correction of 9 main tidal waves (M2, S2, K1 and O1 in the East China Sea) of nine VLBI stations in East Asia were calculated. The radial and horizontal displacements of Japan VLBI station are 3 ~ 12mm and 1 ~ 3mm respectively. The corresponding radials of VLBI1 station in Shanghai and Daejeon station in Korea are 1mm and 3 ~ 4mm, respectively. It is estimated that the baseline load changes from Shanghai to Japan at Kashima and Shui Station are respectively ± 7.6 mm and ± 28.4 mm. In addition, the load-gravity changes of Japan’s water, Nobeyama, Kagoshima and Usuda stations are respectively 0.8 to 0.9 μGal, which is close to the current absolute gravimetric measurement accuracy of ± μGal. Calculations also show that the difference in calculated load displacements for different Earth models can be neglected at the current geodetic level of precision.
