Eight bursting phases, which consist of a total of 353 individual bursts, are identified. We further analyze the periodic properties of our sample using the Lomb-Scargle periodogram. The result suggests that those bursts exhibit a period of ~238 days with a ~63.2% duty cycle. Based on our analysis, we further predict two upcoming active windows of the X-ray bursts. Since 2021 July, the beginning date of our first prediction has been confirmed by the ongoing X-ray activities of the SGR J1935+2154.   Discovery and Timing of Pulsars in the Globular Cluster M13 with FAST 期刊论文  OAI收割 ASTROPHYSICAL JOURNAL, 2020, 卷号: 892, 期号: 1, 页码: 43 作者:  Wang, Lin;  Peng, Bo;  Stappers, B.
