Definition

一再 and 屡屡 both Adverbs, which means “time and again; repeatedly”.

Example

一再 and 屡屡 both mean"repeatedly", and are usually interchangeable, but they have different stresses.
一再 stresses the importance and seriousness of the behavior, while 屡屡 stresses the frequency.

In examples ③ and ④, since the importance of the action is stressed, 一再 is used and cannot be replaced by 屡屡.

It is worth noting that 一再 and 屡屡 are both applied to man's subjective action. For example, we cannot use 屡屡 to modify 下雨, so does 一再, but we say 经常下雨 (it rains often).
