就其本身而言，由于光的散射与反射，这一坦克立体构型清晰可见，如同日常所见的物品。
On its own, the three-dimensional object was clearly visible because light scattered and reflected off the tank's features, as it does with all everyday objects, black or otherwise.
而空气污染又使光污染问题愈发严重，因为漂浮在空气中的小颗粒通过散射和反射光线，加剧了这一问题。
Light pollution is made worse with air pollution, as the small particles that float in the air serve to scatter and reflect the light, compounding the problem.
