1、A slot represents a time unit such as si.
一個(gè)槽位代表一個(gè)時(shí)間單元，如si(槽位時(shí)間間隔)。

2、The major scale units must be a larger time unit than the minor scale units.
主刻度代表的時(shí)間單位必須比次刻度的大。

3、And the time unit might be a few nanoseconds or whatever, and then it is a good approximation.
時(shí)間元可以是幾微秒或別的，這就是一個(gè)很好的近似值了。
