resolving aperture

基本解释

For example, the resolving power of an 8" aperture telescope is 0.6 seconds of arc (4.56 divided by 8 = 0.6).
比如，孔径为8英寸的望远镜的分辨能力是0.6角秒(4.56/8 = 0.6)。
In theory, when you double the aperture of a telescope, you increase its resolving power by a factor of two and boost its light gathering ability by a factor of four.
理论上，当你将望远镜的孔径放大一倍，它的分辨能力就会增加1倍，它的集光力就会增加为原来的4倍。
The theoretical resolving power of a telescope is 4.56 divided by the aperture of the telescope (in inches).
望远镜的理论分辨能力是4.56除以望远镜的孔径(单位：英寸)。
