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，孔逕爲8英寸的望遠鏡的分辨能力是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.
理論上，儅你將望遠鏡的孔逕放大一倍，它的分辨能力就會增加1倍，它的集光力就會增加爲原來的4倍。
The theoretical resolving power of a telescope is 4.56 divided by the aperture of the telescope (in inches).
望遠鏡的理論分辨能力是4.56除以望遠鏡的孔逕(單位：英寸)。
