2.The gegenschein is distinguished from zodiacal light near the Sun by the high angle of reflection.
与发生在太阳附近的黄道光的区别就在于对日照的高反射角度。
3.Pictured above, the gegenschein is seen superposed toward the constellation of Pisces.
如图所示，与双鱼座方向重叠的位置可以看到对日照。
4.The gegenschein is sunlight back-scattered off small interplanetary dust particles.
对日照是非常小的星际尘埃上的阳光反向散射。
5.The gegenschein is distinguished from zodiacal light by the high angle of reflection.
对日照通过高角反射在黄道带的光圈中很容易辨明。
