| 摘 要： | 就压力式验潮仪观测数据的预处理、仪器改正、海水密度改正、滤波光滑处理等方法进行了探讨。对由于仪器原因或因缺电造成的缺损数据的修复,首次提出了利用调和相关差分的方法进行数据的恢复,这种方法还可以用于海底自容压力式验潮仪的沉降检测和改正。经过分析比对,此次渤海航路测量水位改正的均方差优于10 cm,证明这些潮汐数据分析处理方法合理可靠。

| Abstract: | The tidal data gross error detection method,the correction of the instrument,the sea-water density correction and the filtering processing method have been discussed in this paper.For the purpose of recovering the missed tidal data caused by the instruments or other reasons,such as electricity supply failing,the tidal harmonic correlation differential method is presented.This method could be used to detect and correct the sedimentation of self-contained water pressure gauge on the seabed.By comparing with the previous results,the water correction scale of this Bohai survey is less than 10cm,which proves that these methods are reasonable and reliable. |
