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.   Mechanisms, influencing factors, and applications of electrohydrodynamic jet printing 期刊论文  OAI收割 Nanotechnology Reviews, 2021, 卷号: 10, 期号: 1, 页码: 1046-1078 作者:  Cai SX(蔡树向);  Sun, Yalin;  Wang, Zhen;  Yang WG(杨文广);  Li, Xiangyu   |  收藏  |  浏览/下载：40/0  |  提交时间：2021/10/03 electrohydrodynamic jet printing  droplet generation process  electronic devices  bioprinting   Waveform control in selective enhancement of single-order harmonic 期刊论文  OAI收割 LASER PHYSICS, 2019, 卷号: 29, 期号: 6, 页码: 10 作者:  Liu, Hui;  Feng, Liqiang   |  收藏  |  浏览/下载：59/0  |  提交时间：2019/06/20 high-order harmonic generation  selective enhancement of single-order harmonic  laser waveform control  two-color chirped pulse  multiple-acceleration process   Theoretical Study of Organic Crystal-Based Terahertz-Wave Difference Frequency Generation and Up-Conversion Detection 期刊论文  OAI收割 Journal of Infrared, Millimeter, and Terahertz Waves, 2018, 卷号: 39, 期号: 10, 页码: 1005-1014 作者:  Liu PX(刘鹏翔);  Qi F(祁峰);  Li WF(李惟帆);  Liu ZY(刘朝阳);  Wang YL(汪业龙)   |  收藏  |  浏览/下载：29/0  |  提交时间：2018/07/31 Nonlinear Optics  Parametric Process  Terahertz-wave Generation  Terahertz-wave Detection  Organic Nonlinear Crystal   Process intensification and integration of solar heat generation in the Chinese condiment sector - A case study of a medium sized Beijing based factory 期刊论文  OAI收割 ENERGY CONVERSION AND MANAGEMENT, 2015, 卷号: 106, 页码: 1295-1308 作者:  Sturm, Barbara;  Meyers, Steven;  Zhang, Yongjie;  Law, Richard;  Valencia, Eric J.
