These phases should show up as tiny variations in the intensity of the observed light, researchers have predicted.

研究人员预计，这些相位应该表现为所观测到的光线在亮度上的微弱变化。

Though the team has yet to quantify this effect, it appears to increase as the intensity of the light increases.

尽管这个团队尚未量化这种效果，但是似乎随着光强度增加，效果会更加明显。

It was not known, though, whether simply altering ambient light intensity might have similar effects.

尽管还不知道是否仅仅简单地改变周围灯光的亮度也会有同样的作用。

The high-intensity light can dazzle pilots during take-off and landing when shone at aircraft.

Similarly located structures less than 45 metres tall may require a low-intensity light.

And under International Civil Aviation Organisation regulations, any structure over 45 metres tall on a flight path or near an aerodrome must be fitted with a medium-intensity aircraft warning light.
