At night, it's the extra-sensitive rods that take over — this is why it's difficult to detect color in low levels of light.

夜间，特别敏感的视杆细胞在眼睛视物占有主导地位—这就是为什么在昏暗的光线条件下我们很难看到事物的色彩。

Scientists still disagree about which planetary systems are extra-sensitive to climate shifts, but the possibility can't be ignored.

也许对于行星系统究竟哪些部分对气候变化格外敏感，科学家们仍然众说纷纭，但是对发生危机的可能性却不能疏忽大意。

Workarounds include the use of extra-sensitive chemicals in traditional films, or amplification of signals captured by the photoelectronic light sensors of digital cameras.

其他的一些改善这个问题的工作包括在传统胶卷上使用超灵敏的化学感光物质，或者对数码相机的光电传感器捕捉到的信号进行放大。
