This is to roughly show the area affected by the light source.

这是为了大概表明下由光源影响的区域。

The result showed that the light distribution in the canopy were obviously affected by the leaf area index (LAI), the structure of canopy, solar radiation and its apparent movement, etc.

结果表明：梨树叶幕光能分布状况直接受叶面积系数、树冠结构、太阳位置及光强的影响。

In solar power plants, birds affected by the solar panels light the area, lower power generation efficiency.

在太阳能电站，鸟类影响太阳能电板的受光面积，降低发电效率。
