The coupled equation of two-wave mixing and expressions for weak beam amplification in a single mode waveguide are deduced by application of coupled wave theory.

本文利用耦合波理论分析推导了单模平面光波导中两波混合的耦合波方程和弱相干光放大率的表示式。

But if linearly superpose the two fundamental wave solution, it does not have the significance because their background are nonlinear.

但简单的将这两个基波解进行线性迭加是没有意义的，因为它们的背景是非线性的。

As the optical precursor and main wave packet traveled through a second group of rubidium atoms, the scientists took measurements on the speed of the two photon components.

随着光前驱和主波包通过第二组铷原子，科学家就可以对这两个光子成分的速度进行测量。

Its Radmax engine uses two wave-shaped cams that rotate above and below a stationary rotor.

First and foremost is the 180-degree swiveling LCD, which, like Samsung's MultiView flavor, flips all the way forward to simplify composition for self-portraits, but it also offers some nifty gesture controls, letting you wave briefly to trigger a two-second countdown, for example.

Waves 2 and 4 are the two minor corrections in the five-wave move higher.
