Finally, when regarding the component wave of irregular wave spectrum as regular wave1 and calculate the wave refraction In shallow water by Snell's law, the result is different from the result analysis by directional spectrum.

将波谱中各频率之波浪视为单一规则波，用 Snell定率计算其折射角，其结果与实测结果并不一致，表示方向波谱中各频率主方向无法利用规则波之原理以简化条件的方法求出。

A general formula for three dimensional refraction of progressive gravity water waves has been derived using the conservation of waves, which has a form the same as that derived using Fermat's principle in optics. For the case of gentle sloping plane beach the formula can be degenerated into the famous Snell's law.

三度空间中前进波浪的折射现象，已依波浪守衡性的本质简明地导述出其主控的通式，且与由较繁冗的光学之Fermat原则所得者完全一致；而最简单的均匀缓坡度底床的特例情况则退化成Snell定律者。
