固体潮调和分析的新算法

A NEW ALGORITHM OF TIDAL HARMONIC ANALYSIS

本文利用差分法对固体潮数据进行调和分析尝试。其结果表明该方法具有原理简单,对数据连续性要求低,解算精度高等优点。且对日波,半日波,1/3日波等三波段的潮汐导纳一次解出,同时得到唯一的比较切实的观测值中误差。

As an attempt, the difference method has been used to analyse the tidal data in this paper. The results show that the method has such advantages that: its principle is simple, the demanded continuity of registrations is low and the accuracy of solution is high. Using the method the admittance of DP, SP and TP tides can be obtained at a lime, and the unique realistic error in observatioal values can be obtained simultaneously.
