太阳在夏天会出现在八字曲线的最高点，在冬天则出现在最低点。 - One simple use for this is to display the Sun's "analemma" - the "figure eight" shape traced out by the Sun at noon over the course of a year.
一个例子是显示太阳的“日行迹”-你一年每天在同一时间记录太阳在天空的位置,就得到太阳的8字型轨迹。 - Explanation: An analemma is that figure-8 curve you get when you mark the position of the Sun at the same time each day throughout planet Earth's year.
