基本解释

The error of current ocean tide model affected global mean sea level in the periods of about 60 and 90 days.
海平面模型误差和不恰当的加权方法都会影响全球海平面序列的周年变化，潮汐模型误差对于季节性变化有明显的影响。
The effect of mean sea level rise is shown by the standing tide wave in the shallow Water areas of the continental shelf.
属于大陆边缘海域的中国黄海，海平面上升影响的显著性，通过驻波作用明显地表现出来。
First, the defmation and status of height datums is introduced and some problems on the local height datums established by the mean sea level, which is defined by the tide gauge data, are discussed.
首先介绍了高程基准的定义与现状，指出了用验潮站长期平均海平面建立局部高程基准所存在的问题；
