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H_2表示。在工程规划设计里,要求知道H_2的累积频率,这项工作费时很多。而求取高潮位(即潮峰,以H_0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H_2与H_0之间的回归方程,然后,根据方程推算H_2的累积频率。结果是令人满意的。 It is necessary to know the climax tide of a certain duration (for example, two hours) at a tidal wave dock, dock, waterway, which is denoted by H2. In engineering planning and design, it is time-consuming to ask for the cumulative frequency of H 2. However, it is easy to find the climax bit (ie the tide peak, denoted by H_0) to accumulate the frequency. A time-saving method is to deduce the regression equation between H_2 and H_0, and then calculate the cumulative frequency of H_2 according to the equation. The result is satisfactory.
