一束光

The plane-parallel resonant cavity is built up in theory with the U-shaped bending waveguide for TM mode. The beam splitting and convergence effect are also discussed for the structure composed of filling-factor graded wave-like 2D-PC and one-dimensional multilayer thin films.

利用TM模的U型转弯波导构建了新型的平行平面谐振腔，并指出由填充率渐变型波状结构二维光子晶体和一维多层薄膜构成的混合结构在光分束和抑制光束发散方面的作用及其在平行平面谐振腔中的潜在应用。

We propose a new mechanism of pupil control in the insect compound eye.

小眼感杆束直径相应变化用光镜方法得到证实，我们认为在昆虫复眼中存在一种新的瞳孔调节机制。

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。
