One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure.

误差的一个来源是折射，即光束通过不同温度和压力的空气层时发生的弯曲现象。

The atmospheric bending of light rays is greatest when the sun is right along the horizon, at sunrise or sunset.

当太阳正好在地平线上的时候，也就是日出和日落的时刻，大气对光线的折射作用的最强的。

youdao

It's like a mirage, where heat causes the bending of light rays and cloaks the road ahead behind an image of the sky.

实验就象海市蜃楼，在高温下，光线发生弯曲，从而前面的道路就看不见了，而只能看到后面的天空图像。

And so will the fortunes of those who get in early and build the right light-bending products.
