查询词典 Snell's law

In this paper, we demonstrate that, based upon boundary conditions and the uniqueness theorem of domain decomposition method for boundary problem of Helmholtz equation, Snell's law may also be derived without adopting phase-matching condition.

该文利用Helmholtz方程边界问题的边界条件和域分解理论，研究了静态面电荷对电磁波在介面传播的影响，理论上得到了一些有物理意义的结果，这对认识电磁波在介面的传播特性有一定参考价值。

Furthermore, for angles of incidence other than 0o, Snell's law (that is, sin I /sin γ=constant) holds for the ordinary but not for the extraordinary ray, since the velocity of the latter is different in different directions.

此外，入射角如果大于零度，根据折射定律(sin I /sin γ=常量)适合于寻常光，但不适于非常光线，因而在不同的方向有不同的速度。

In this paper, by using the Snell's law, we derive a quartic equation for the accurate description of conve...

将这一结果应用于P-SV转换波的速度分析和叠加处理中。简化的公式有较好的应用价值。

The more general form of Snell's law must be used for the wave generated by mode conversion upon reflection.

它是斯奈尔定律一种特殊情况。斯奈尔定律更一般的形式满足由反射波波型转换产生的转换波。

This is a special case of Snell's law.

反射定律：在均匀介质中，同一波的反射角等于入射角。

Snell's law follows from Fermat's principle.

斯奈尔定律遵从费马原理。

That is, movement adds only a fraction of the medium's velocity to the light (predicted by Fresnel in order to make Snell's law work in all frames of reference, consistent with stellar aberration).

即运动增添仅为介质的速度轻(预言菲涅尔为了使斯涅耳定律在各项工作的参照系，符合恒星像差)。

Then,shotpoint-receiver pairs which meet reflec-tion law are found by using Snell's law. Finally,prestack depth imaging is achievedby using constraint weighted Kirchhoff integral. This method is adaptable to thevertical and lateral variation...

本方法适应速度的纵向和横向变化，它优于简单的VSP－CDP资料转换成像方法，通过模型和实际资料的成像应用表明，此法不仅成像精度高，而且有利于改善剖面的频率特性。

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。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
