【摘要】 提出一种特殊日期潮汐推算图的制作方法,用于确定潮汐特性不符合余弦规律变化的潮汐港中任意时刻的潮高或任意潮高的潮时,并以湛江港为例,给出该潮汐推算图的使用方法。其优点是可准确求出非余弦规律变化曲线条件下的潮汐推算,不需要内插计算,可以直接在图上读取任意潮高和任意潮时。更多还原

【Abstract】 A tidal calculation chart is put forward for a special date to determine the tidal height or tidal moment,which not conform cosine curve. It gives a tidal calculation chart making and its usage on a special date in Zhanjiang port. This new tidal calculation chart has the following advantages:exactly make out the tidal height or tidal moment which not conform cosine curve,need not any interpolation,and you can directly read the tide or its moment from this chart.更多还原
