摘要
Using the model data for surface mass changes of the atmosphere, ocean, soil moisture and snow depth, the vertical crustal displacements of 25 ficual stations in China were calculated according to the loading theory. From the spectral analysis of the results, we can see that the periods of displacements are 12 months and the semi-periods are 6 months. The results also show that the maximum seasonal displacements can reach 20 mm and even larger. The covariance analyses and significance tests show that the coefficients of 96 percent of the stations are significant at the 0.1 significance level. The results show that one of the reasons of the vertical crustal displacements is the changing surface fluid loads.
用为空气，海洋，土壤湿度和雪深的表面团变化的模型数据，在中国的 25 个 ficual 车站的垂直外壳的排水量根据装载理论被计算。从结果的光谱分析，我们能看到排水量的时期是 12 个月，半时期是 6 个月。结果也证明最大的季节的排水量能到达 20 公里并且甚至更大。96% 车站的系数在 0.1 意义水平是重要的协变性分析和显著性检验表演。结果证明垂直外壳的排水量的原因之一是变化表面液体负担。
