摘要：

乘潮作业的港口、船坞、航道,需要了解某一持续时间(例如两小时)的高潮潮位,这里以H2表示。在工程规划设计里,要求知道H2的累积频率,这项工作费时很多。而求取高潮位(即潮峰,以H0表示)累积频率则是容易之事。一种节省时间的方法就是推求H2与H0之间的回归方程,然后,根据方程推算H2的累积频率。结果是令人满意的。

In order for harbors, docks and channels to have enough depths to operate, the higher tide above a height held a duration, e.g. two hours (denoted by H2) should be known. In the design and project of an engineering, the accumulated frequency of H2 is required,which takes much time. On the other hand, it is easy to obtain the accumulated frequency of high tide (crest tide), denotea by H0. Therefore, an economical way is deriving the regression equation between H2 and H0 and computing the accumulated frequency of H2 from the derived equation. The results are satisfactory,
