The place had recently been painted a bright but disgusting yellow, and the light reflecting off the walls made everyone inside look as though they had hepatitis!

这个地方不久前把墙漆上了一种抢眼但又难看的黄色，墙面反射的光线使里面的每一个人看起来都像得了肝炎。

The amount of light lost between bounces also puts a limit on how far away an object can be from the reflecting wall before the technique stops being useful.

来回反射间损失的光量也限制了这项技术要起作用物体可以距离反射墙面多远。
