滑动平均法在海量潮位数据处理中的应用

In order to get high tide level and low tide level and their corresponding time respectively from the statistic characteristics of huge amount of tidal data, the slide average method combined with the character that high tide and low tide appear alternately to obtain characteristics of high tide and low tide automatically is presented. The application of the method to the measured tidal records of Wusong hydrology station of Shanghai hydrology bureau shows that the calculation results is right and credible.
