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.   Gas Multiple Flow Mechanisms and Apparent Permeability Evaluation in Shale Reservoirs 期刊论文  OAI收割 SUSTAINABILITY, 2019, 卷号: 11, 期号: 7, 页码: 21 作者:  Feng, Xuelei;  Ma, Fengshan;  Zhao, Haijun;  Liu, Gang;  Guo, Jie   |  收藏  |  浏览/下载：52/0  |  提交时间：2019/06/24 shale gas  multiple flow mechanisms  apparent permeability model  dynamic permeability evaluation  numerical simulation   Spontaneous recovery and time course of biological motion adaptation 期刊论文  OAI收割 VISION RESEARCH, 2018, 卷号: 149, 页码: 40-46 作者:  Mei, Gaoxing;  Yuan, Qi;  Liu, Guoqing;  Pan, Yun;  Bao, Min   |  收藏  |  浏览/下载：68/0  |  提交时间：2018/09/10 Biological Motion  Visual Adaptation  Spontaneous Recovery  Multiple Mechanisms  Timescale   Compromise in competition between free energy and binding effect of intrinsically disordered protein p53 C-terminal domain 期刊论文  OAI收割 MOLECULAR SIMULATION, 2017, 卷号: 43, 期号: 2, 页码: 110-120 作者:  Han, Mengzhi;  Xu, Ji;  Ren, Ying 收藏  |  浏览/下载：40/0  |  提交时间：2017/03/24 Tumour Suppressor P53  Multiple Mechanisms  Dynamic Structures  Compromise In Competition  Free Energy Landscape  Molecular Dynamics   The principle of compromise in competition: exploring stability condition of protein folding 期刊论文  OAI收割 Science Bulletin, 2015, 期号: 1, 页码: 76-85 Xu, J.; Han, M.
