In this study, we present the investigation of nonstationary QPPs with multiple periods during the impulsive phase of a powerful flare on 2017 September 6, which were simultaneously measured by the Hard X-ray Modulation Telescope (Insight-HXMT), as well as the ground-based BLENSW. The multiple periods, detected by applying a wavelet transform and Lomb-Scargle periodogram to the detrended light curves, are found to be ~20-55 s in the Ly`and mid-ultraviolet Balmer continuum emissions during the flare impulsive phase. Similar QPPs with multiple periods are also found in the hard X-ray emission and low-frequency radio emission. Our observations suggest that the flare QPPs could be related to nonthermal electrons accelerated by the repeated energy release process, i.e., triggering of repetitive magnetic reconnection, while the multiple periods might be modulated by the sausage oscillation of hot plasma loops. For the multiperiodic pulsations, other generation mechanisms could not be completely ruled out.   黄土高原不同恢复年限和降水梯度下人工刺槐林土壤水分时空动态 学位论文  OAI收割 北京: 中国科学院大学；中国科学院生态环境研究中心, 2020 作者:  陈维梁   |  收藏  |  浏览/下载：15/0  |  提交时间：2022/06/09 黄土高原  土壤水分  恢复年限  降水梯度  湿润锋  (I.e., Hp, Zjy And Rjt, 10-30%) Were Significantly Higher Than That Of The North Plots
