食季与沙罗周期像时钟一样来了又走了。
Eclipse seasons and saros cycles come and go like clockwork.
在沙罗周期系列中相继发生的日全食的路径每隔18年作有规律的图形变化。
The paths of totality for successive eclipses in this saros series change in a regular pattern every 18 years.
下面地图上的日食都是在同样的沙罗周期系列中发生的，彼此相隔18年又10或11天。
The eclipses on the following map are all in the same saros series, each separated by 18 years and 10 or 11 days.
沙罗周期日数约为朔望月周期（29.53日）、交点月周期（27.21 日） 和近点月周期（27.55 日） 的最小公倍数。
It is approximately the LCM (lowest common multiple) of the synodic period (29.53 days), draconic period (27.21 days), and the anomalistic period (27.55 days) of the Moon.
