| 摘 要： | 文中介绍了一个新的引潮位展开,含有潮波3070项及一些新的信息;潮波振幅给至小数点后第6位.为了与精密引潮位比较,专门建立了一套标准数据,其精度为±0.001μGal.按照这一标准数据,我们评价了精密引潮位展开的精度,并给出了其余差及功率谱分析的结果.结果表明,对于潮汐重力,精密引潮位展开的精度,可达±0.005μGal.

| Abstract: | In this paper a new tidal development is introduced, which includes 3070 tidal waves and some new information. The amplitudes are given to the 6th place of decimals. In order to evaluate the precision of the tidal development, a standard data set with accuracy about±0.001 μGal was established for comparison. According to this data set we evaluated the precision of the development of the tidal generating potential. The results of residues and power spectrum analysis are given. |
