摘　　要：针对使用自容式压力验潮仪在布设临时验潮站时常出现的验潮零点漂移技术难题,基于附近长期验潮站的潮汐观测数据来计算二站同步时段内逐时日平均海面之差值,以此修正临时验潮站观测数据中隐含的验潮零点逐时漂移量。以福建平潭长期站和王爷山、牛山岛两个临时站的验潮数据为例,进行了自容式压力验潮仪验潮零点漂移处理的实践。结果表明本文相关模型具可操作性和实用价值。Aiming at the technical problem o f tide zero point drift with the using of self-contained pressure tide gauge when lay temporary tide gauge stations,the difference between the daily mean sea level in the synchronous periods of the two tidal gauge stations is calculated based on hourly data o f the nearby long-term tide gauge station.In this w ay,th e implicit tide zero point drift in the observation data of the temporary tide station can be corrected.Taking the long-term station of Pingtan and the temporary stations of Wangyeshan and Niushandao in Fujian province as exam ples,the tide point zero drift of pressure tide gauge tide station is carried out.The results show that the relevant model in this paper is feasible and practicable.
