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.   Optical Emission Spectroscopy Diagnostics of Atmospheric Pressure Radio Frequency Ar-H-2 Inductively Coupled Thermal Plasma 期刊论文  OAI收割 IEEE TRANSACTIONS ON PLASMA SCIENCE, 2020, 卷号: 48, 期号: 10, 页码: 3621-3628 作者:     |  收藏  |  浏览/下载：39/0  |  提交时间：2021/03/29 Plasma temperature  Radio frequency  Electron tubes  Integrated optics  Stimulated emission  Hydrogen  Diagnostics  electron excitation temperature  inductively coupled thermal plasma (ICTP)  optical emission spectroscopy (OES)  thermal efficiency   Enhanced removal of X-ray-induced carbon contamination using radio-frequency Ar/H-2 plasma 期刊论文  OAI收割 Nuclear Science and Techniques, 2019, 卷号: 30, 期号: 2, 页码: 9 作者:  Y.Wang;  Q.P.Lu;  Y.G.Gao;  X.P.Gong;  Y.Song   |  收藏  |  浏览/下载：38/0  |  提交时间：2020/08/24 Radio-frequency plasma,X-ray irradiation,Carbon contamination,hydrogen,ion,erosion,Nuclear Science & Technology,Physics   Properties evolution of additive manufacture used tungsten powders prepared by radio frequency induction plasma 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF REFRACTORY METALS & HARD MATERIALS, 2017, 卷号: 67, 页码: 90-97 作者:  Wang, Lin-zhi;  Wu, Jiao-jiao;  Zhang, Dai-jun;  Wang, Lin-zhi;  Wu, Jiao-jiao   |  收藏  |  浏览/下载：30/0  |  提交时间：2018/03/05 Tungsten powders  Flowability  Laser absorption coefficient  Particle size distribution  Radio frequency induction plasma  Additive manufacturing   Radio frequency heating induced edge plasma convection: self-consistent simulations and experiments on ASDEX Upgrade 期刊论文  OAI收割 Nuclear Fusion, 2017, 卷号: 57 作者:  Zhang,W.;  Tierens,W.;  Noterdaeme,J-M.;  Bobkov,V.;  Aguiam,D.   |  收藏  |  浏览/下载：34/0  |  提交时间：2021/11/01 edge plasma convection  radio frequency heating  self-consistent simulation  scrape-off layer   Fabrication and characterization of He-charged ODS-FeCrNi films deposited by a radio-frequency plasma magnetron sputtering technique 期刊论文  OAI收割 PLASMA SCIENCE & TECHNOLOGY, 2017, 卷号: 19, 期号: 4, 页码: 1-8 作者:  Song, Liang;  Wang, Xianping 收藏  |  浏览/下载：179/0  |  提交时间：2018/07/04 Radio-frequency Plasma Magnetron Sputtering  He-charged Fecrni-based Film  Nanoindentation Hardness  Elastic Recoil Detection  He Implantation   Tokamak Plasma Flows Induced by Local RF Forces 期刊论文  OAI收割 PLASMA SCIENCE & TECHNOLOGY, 2015, 卷号: 17 作者:     |  收藏  |  浏览/下载：50/0  |  提交时间：2020/10/26 TOROIDAL ROTATION  GENERATION  DRIVEN  TRANSPORT  INJECTION  low hybrid wave (LHW)  ion cyclotron radio frequency (ICRF)  mode-conversion  plasma rotation  plasma flow  RF force
