limiting magnitude
常见例句
- A rough formula for calculating visual limiting magnitude is: 7.5 + 5 LOG (aperture in cm).
一个计算视觉边缘亮度的粗略公式是：7.5 + 5 LOG (孔径尺寸/cm)。 - It can measure the magnitude characteristic, phase characteristic and limiting frequency of a system.
它能直观的测试一个系统的幅频特性、相频特性和截止频率。 - The limiting magnitude is directly related to aperture, where larger apertures allow you to see fainter stars.
边缘亮度直接与孔径相关，孔径越大，就能看到越暗的星。 返回 limiting magnitude
