People on the bus wave. A very fat lady crossing the street says. You sure got quite a load there.
巴士上的人向我们挥手。一个很胖很胖的女人边过街边说，你们的装载量很大呀。

We have studied the level crossing effect in degenerate four-wave mixing and compared it with the level crossing effect in resonance fluorescence.
研究了简并四波混频的能级交叉效应，并与共振荧光的能级交叉效应比较。

The reflection and refraction of traveling wave are quite complicated at the sheath-crossing point of high voltage power cable, due to its remarkably noncontinuous surge impedance.
