在这种情况下，镜头需要有能力尽可能多的收集光源的信号(更大的光通量)，从而可以得到一个更高的分辨率。
In this case, the ability of a lens to collect as completely as possible the light signals from the sources and therefore give a higher resolution is readily pursued.
光通量减弱使乙醛和甲苯的降解率均下降。
Decreasing light intensity, the degradation of acetaldehyde and toluene both decreased.
