Spherical aberrations的用法和樣例：
例句
- A very small lens aperture is employed to correct spherical aberration, but this sevrely limits the final resolution.
可以用一個非常小的透鏡孔闌來校正球差，但這會嚴重地影響最終鑒別率。 - Cloudy Nights ask me to explain what the spherical aberrations undercorrected and overcorrected mean and how to tell what you have as you almost always have at least one.
論壇讓我再解釋一下球差較正不夠和過度是什麼意思，以及如何辨別。
