查询词典 snell

The sound pressure fields at M=0, M=0.1 and M=0.2 are also given out. It is found that the constant pressure contours at the distances not too far from the duct end are caved-in backward due to the effect of flow. And it can be explained using Snell's law.

同时还给出了M=0、M=0.1和M=0.2管口辐射声场的声压分布，发现流动使离管口稍远处声压等值线向管口方向凹陷，并用Snell定律作了解释。

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。

In fact, starting with rays implies the use of Snell's law.

事实上，从光线概念开始的教学意味着Snell定律的使用。
