supernumerary rainbow的意思|示意

美 / sjupəˈnju:mərəri ˈreinbəu / 英 / ˌsjupɚˈnuməˌrɛri ˈrenˌbo /

多余虹

So as the saying goes, roses are red, violets are blue, and purple in a rainbow is a supernumerary hue.

所以正如俗话说红玫瑰紫罗兰，蓝紫的彩虹就是多余环。

It sounds complicated, but really a supernumerary rainbow is one with smaller repeating rainbows inside it.

听起来似乎复杂，但真正的复式彩虹是在其一个彩虹内部还有一个较小的彩虹。
