At the crotch or junction, these flukes slightly overlap, then sideways recede from each other like wings, leaving a wide vacancy between.

分叉或合处，这两片尾叶略有重叠，然后像一翅膀那样彼此斜着分开，中间留下一个很宽的空隙。

When a photon hits this junction of materials in the photodiode, called a p-n junction, an atom's electron absorbs the photon's energy, and as a result, it jumps up to a higher energy state and leaves the atom.

当一个光子击中光电二极管中的材料合处，也就p-n结时， 原子的电子会吸收光子的能量，从而跃迁到更高的能级并离开原子。
