简介:一个算法(微分模式)为沿着T/P的潮汐的分析追踪的泛音的改进被介绍,在哪个在邻近的点的观察海面高度之间的差别作为观察被拿。另外,观察方程与转线路分析的结果被抑制;参数估计被最少的广场在0.1°纬度间隔执行。盖住中国海和西北太平洋的周期10~330T/P高度表数据(2°-50°N,105°-150°E)为精制沿着轨道泛音被采用在8474个点的12成分的潮汐的分析,和泛音常数被获得,它显示算法罐头高效地在高度表观察移开非潮汐的效果,并且改进潮参数的精确。而且,沿着测高法轨道的参数比传统的算法获得的那些代表更光滑的分布。在从11厘米的潮汐的高度模型和到1.3厘米的观察还原剂之间的恰当的错误的根平均数广场。
