本文介绍了固体潮观测数据的平滑检验和NAKAI法检验之方法原理和具体应用。平滑检验可以有效地监测並改正观测数据中的随机错误,突跳或坏读数;经平滑改正后,可使观测数据的读数误差小于1毫米。用NAKAI(1975)提出的方法检验观测数据可以监测仪器灵敏度变化情况和数据质量好坏,根据该检验计算获得的有关参数(主要是漂移系数和方差)剔除质量不好的48小时数据组或修正某些质量不好的数据可提高调和分析结果的精度。
This paper introduces the method of smoothing test of solid tide observation data and NAKAI method and its application. Smoothing test can effectively monitor and correct random errors, sudden jumps or bad readings in observed data. After smooth correction, the reading error of observed data can be less than 1mm. Using the method proposed by NAKAI (1975) to test the observed data can monitor the sensitivity of the instrument and the quality of the data. The relevant parameters (mainly the drift coefficient and variance) calculated from the test are removed from the poor quality 48-hour data set or corrected Some poor quality data can improve the accuracy of harmonic analysis results.
