Third, on the design of omni-directional reflector, we designed the stent system by controlling an external parameter.

第三，在全向反射面的设计基础上，设计了外部参数可调的支架系统。

Also remember that bouncing light-even into a shiny reflector that keeps light directional - adds to the distance it travels.

同样还要注意的是，经过反射的光线其行进的距离也会增加，即使使用光面反光板也一样。
