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.   A novel photochromic ceramics with reversible luminescence modulation and light bleaching behavior: Sm3+-doped KSr2Nb5O15 期刊论文  OAI收割 JOURNAL OF THE EUROPEAN CERAMIC SOCIETY, 2020, 卷号: 40, 期号: 15, 页码: 6061-6072 作者:  Cao, Shuyao;  Chen, Qian;  Liu, Junting;  Wu, Changying;  Li, Leilei   |  收藏  |  浏览/下载：106/0  |  提交时间：2020/10/22 Photochromism  Luminescence modulation  Light bleaching  Tetragonal tungsten bronze structure  Sintering atmosphere   Enhanced Phase Retrieval Method Based on Random Phase Modulation 期刊论文  OAI收割 Applied Sciences-Basel, 2020, 卷号: 10, 期号: 3, 页码: 10031184-1-11 作者:  Li, Fanxing;  Yan, Wei;  Peng, Fupin;  Wang, Simo;  Du, Jialin   |  收藏  |  浏览/下载：43/0  |  提交时间：2021/05/11 Random Phase Modulation  Phase Retrieval  Spatial Light Modulator   High-speed focusing and scanning light through multimode fiber 会议论文  OAI收割 Shanghai, China, 2020-10-17 作者:  Geng, Yi;  Zhang, Zaikun;  He, Zhengquan;  Chen, Hui;  Wang, Ruiduo   |  收藏  |  浏览/下载：32/0  |  提交时间：2021/01/20 Light focusing  amplitude-only modulation  multimode fiber  spot-scanning imaging   Dual-response and Li+-insertion induced phase transition of VO2-based smart windows for selective visible and near-infrared light transmittance modulation 期刊论文  OAI收割 SOLAR ENERGY MATERIALS AND SOLAR CELLS, 2019, 卷号: 200 作者:  Jia, Hanxiang;  Cao, Xun;  Shao, Zewei;  Long, Shiwei;  Jin, Liangmao   |  收藏  |  浏览/下载：97/0  |  提交时间：2019/12/26 VO2-based smart window  Selective light modulation  Dual-response  Phase transition  Li+-insertion
