因此，反向发射的光被二向色滤光片106朝向波长转换元件110反射。
Thus, back emitted light is reflected by the dichroic filter 106 towards wavelength converting element 110.
如图2所示，光的一部分将被朝向发光装置102反向发射，在此它将被二向色滤光片反射用于再循环。
As shown in FIG. 2, a portion of the light will be emitted back towards the light emitting device 102, where it will be reflected by the dichroic filter for recycling.
但是在那种情况下，站在岸上的人将会发现向船前进的方向发射的子弹将比向反向发射的子弹运动得要快。
But in that case, someone standing on the shore would find that a bullet fired in the direction in which the boat was heading would be travelling faster than one fired in the opposite direction.
