摘要
提出采用时差法的相关系数和最小二乘潮位拟合法的推算中误差,作为潮汐性质相似性强弱判断的两个量化指标。根据实测潮汐数据进行了有关计算,结果表明这两个指标可以用于潮汐性质相似性强弱的快速判断,另外推算中误差还可以用于验潮站潮位数据缺测时推算精度的检验,建议在沿岸海道测量水位改正作业中综合使用。
Both the related coefficient of time lag method and fitting mean square error of the least square fitting method are adopted for the indexs in judging comparability about tide kind. Some examples are adopted according the tidal observation. Results indicates the validity of the two indexs which can be used in water correction of coastal hydrographic surveying.
