摘　　要：考虑到利用中数法计算的日平均海面可能残留较多的短周期分潮影响,会给验潮站零点的漂移检测及修订引入一项潜在的系统差,进而影响到潮汐分析及水深测量水位改正等应用。提出了基于Godin法计算日平均海面的验潮站零点漂移检测及修正的改进方法。应用结果表明Godin法较中数法可明显削弱短周期分潮影响,从而可提高验潮站零点漂移检测及修订的精度。The daily mean sea level will be influenced by the remaining short period constituent when using a simple mean method,thus a potential system error will be introduced into the zero drift detecting and amending,and it will affect tidal analysis and water level correction in bathymetry. A newmethod using Godin is introduced into the zero drift detecting and amending. Some detail analyses are made. It is obvious that the newmethod can reduce the influence of the remaining short period constituent and enhance the precision of zero drift detecting and amending.
