这使得他们可以记录下最大可能的亮度输出,比热机后亮度下降测得的数值更高。
This enables them to record the brightest possible output, prior to the degradation that occurs after it warms up.
黯淡的持续时间说明了该行星的大小,而其亮度下降的时间间隔说明了行星轨道的长度。
The duration of the dip tells the size of the planet, and the time between the light dips tells the length of the planet's orbit.
即使变焦调整到最远端,机器的亮度输出也仅仅下降23.5%,这与有些带两倍变焦的机器40%的亮度下降相比实在是出色许多。
Over the entire range of the zoom, light output is only decreased by 23.5%, which is far less than the 40% which is not unusual for a 2.0:1 zoom.
