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.   Analysis on the mechanisms of coseismic temperature negative anomaly in fault zones 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2020, 卷号: 63, 期号: 4, 页码: 1422, 1430 作者:  Yang XiaoQiu;  Lin Weiren;  Yeh En-Chao;  Xu HeHua;  Xu ZiYing   |  收藏  |  浏览/下载：42/0  |  提交时间：2020/09/22 The mechanisms of coseismic temperature responses  Coseismic stress release  Surface free energy  Frictional heating  Chi-Chi earthquake  Wenchuan earthquake  Tohoku earthquake   Oxytocin mediates early experience-dependent cross-modal plasticity in the sensory cortices 期刊论文  OAI收割 NATURE NEUROSCIENCE, 2014, 卷号: 17, 期号: 3, 页码: 798-807 Zheng, JJ; Li, SJ; Zhang, XD; Miao, WY; Zhang, DH; Yao, HS; Yu, X 收藏  |  浏览/下载：47/0  |  提交时间：2014/07/30 PRIMARY VISUAL-CORTEX  RELEASE  VASOPRESSIN  AUTISM  NEUROSCIENCE  ENVIRONMENT  MECHANISMS  DISORDERS  RESPONSES  CIRCUITS   Thermal evolution of helium in magnetron sputtered titanium films 期刊论文  OAI收割 Nuclear Instruments & Methods in Physics Research Section B-Beam Interactions with Materials and Atoms, 2014, 卷号: 336, 页码: 6-11 J.
