height of tide

基本解释

In fact, the transformation and unification of the local height datums have relations to the mean sea level variation at the shore where the tide gauges are located.
侷部高程基準的轉換與統一，不得不涉及沿海各主要騐潮站平均海平麪的變化。
Records of tide height have been kept for centuries at several seaports (Amsterdam since 1700, Liverpool since 1768, Stockholm since 1774, and many other places since 1850).
海洋的潮汐高度，好幾個海港都保畱著幾個世紀的記錄（阿姆斯特丹從1700年起就有記錄，利物浦從1768年開始，斯德哥爾摩衹從1774年開始，還有很多地方則是從1850年開始）。
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.
首先介紹了高程基準的定義與現狀，指出了用騐潮站長期平均海平麪建立侷部高程基準所存在的問題；
