height of tide

基本解釋

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.
局部高程基準(zhǔn)的轉(zhuǎn)換與統(tǒng)一，不得不涉及沿海各主要驗(yàn)潮站平均海平面的變化。
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(gè)海港都保留著幾個(gè)世紀(jì)的記錄（阿姆斯特丹從1700年起就有記錄，利物浦從1768年開(kāi)始，斯德哥爾摩只從1774年開(kāi)始，還有很多地方則是從1850年開(kāi)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(zhǔn)的定義與現(xiàn)狀，指出了用驗(yàn)潮站長(zhǎng)期平均海平面建立局部高程基準(zhǔn)所存在的問(wèn)題；
