We call that line the terminator.

我们称之为晨昏线。

I made the Cowardly Lion look like the terminator.

Across the terminator, the line of light and shadow stretching across the partial moon, Galileo saw it had areas of high and low terrain.

All this means that life could be possible in the terminator zone, the thin strip of land between the two sides.

所有这一切都意味着生命可能存在于终结地带，即两侧之间的狭长地带。
