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.   Pollution zone identification research during ozone pollution processes 期刊论文  OAI收割 ENVIRONMENTAL MONITORING AND ASSESSMENT, 2020, 卷号: 192, 期号: 9, 页码: 18 作者:  Li, Dongyue;  Liao, Yilan   |  收藏  |  浏览/下载：27/0  |  提交时间：2021/03/18 Pollution zone  Pollution process  Spatio-temporal clustering  Image fusion  Frequency pattern   Pollution zone identification research during ozone pollution processes 期刊论文  OAI收割 ENVIRONMENTAL MONITORING AND ASSESSMENT, 2020, 卷号: 192, 期号: 9, 页码: 18 作者:  Li, Dongyue;  Liao, Yilan   |  收藏  |  浏览/下载：32/0  |  提交时间：2021/03/18 Pollution zone  Pollution process  Spatio-temporal clustering  Image fusion  Frequency pattern   Occurrence frequencies and regional variations in Visible Infrared Imaging Radiometer Suite (VIIRS) global active fires 期刊论文  OAI收割 GLOBAL CHANGE BIOLOGY, 2020, 卷号: 26, 期号: 5, 页码: 2970-2987 作者:  Li, Peng;  Xiao, Chiwei;  Feng, Zhiming;  Li, Wenjun;  Zhang, Xianzhou   |  收藏  |  浏览/下载：34/0  |  提交时间：2020/05/19 active fires  occurrence frequency  spatio-temporal characteristics  tropical region  Visible Infrared Imaging Radiometer Suite (VIIRS)   Occurrence frequencies and regional variations in Visible Infrared Imaging Radiometer Suite (VIIRS) global active fires 期刊论文  OAI收割 GLOBAL CHANGE BIOLOGY, 2020, 卷号: 26, 期号: 5, 页码: 2970-2987 作者:  Li, Peng;  Xiao, Chiwei;  Feng, Zhiming;  Li, Wenjun;  Zhang, Xianzhou   |  收藏  |  浏览/下载：43/0  |  提交时间：2020/05/19 active fires  occurrence frequency  spatio-temporal characteristics  tropical region  Visible Infrared Imaging Radiometer Suite (VIIRS)
