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.
但有时，即使当系统在没有相互重叠时，这一对恒星的整体亮度也会明显下降——暗示着，还有第三个物体围绕着这一对恒星作轨道运转。
Sometimes, however, the system's overall brightness dipped even when the stars were not eclipsing each other-hinting at the presence of a third body orbiting the binary pair.
综上所述，减少电压5%能使灯泡的使用寿命延长至少2倍，但是其亮度会下降20%。
The net result is that a 5% reduction in the voltage more than doubles the life of the bulb, but delivers 20% less light.
漆面的亮度和深度都大大下降，使漆面渐渐发白，构成氧化层，缩短车漆的寿数。
The surface brightness and depth are greatly decreased, the surface oxide layer formed gradually white, paint, shorten life.
结果表明，随着亮度不均匀性增大，判断效绩下降。
The results showed that as the brightness uneven increased, the reading performance decreased.
淬火和不包铜退火处理的材料的亮度大大下降。
The brightness of the material treated by quenching and no-Cu-coating annealing was great reduced.
淬火和不包铜退火处理的材料的亮度大大下降。
