Abstract: Burst detection is an inherent problem for data streams，so it has attracted extensive attention in research community due to its broad applications.Burst on data stream means abnormal number of data emerges during current period of time comparing with last period of time.How to detect burst in data stream real-timely and accurately，which has been a hotspot in stream mining domain.This paper summarizes current research works in burst detection，sums up and analyzes the applicability of existing works and gives the focus of these researches.Finally the future in this area is given.

Key words: data stream, burst detection, elastic window, sliding window
