Here, nine more TGFs of this scenario are reported with concurrent LF sferics and lightning location data. The gamma ray production in these TGFs preceded the occurrence of NBEs by a minimum of 60 µs up to 13.5 ms, and no other fast leader discharge was found within 20 ms before the TGF. The TGF preceded positive NBEs occurred at altitudes of 8.6-11 km in thunderstorms, likely in the high electric field (E field) region of lightning initiation. The analyses show that the NBE preceding TGFs bear harder energy spectrum with larger proportion of high energy photons than EIP related TGFs produced in association with lightning leader. Our findings support the relativistic feedback mechanism of gamma ray generation in the large scale thunderstorm E field.   RF spectrum measurement of the versatile microcavity soliton combs 会议论文  OAI收割 Nantong, China, 2021-10-10 作者:  Hu, Hao;  Wang, Ruolan;  Chen, Liao;  Wang, Weiqiang;  Zhang, Chi   |  收藏  |  浏览/下载：27/0  |  提交时间：2022/01/27 Dissipative Kerr solitons  microresonator  radio frequency spectrum  autocorrelation trace   Measurement of collision frequency shift in strontium optical lattice clock 期刊论文  OAI收割 ACTA PHYSICA SINICA, 2019, 卷号: 68, 期号: 23, 页码: 6 作者:  Lu Xiao-Tong;  Li Ting;  Kong De-Huan;  Wang Ye-Bing;  Chang Hong   |  收藏  |  浏览/下载：22/0  |  提交时间：2021/11/29 collision frequency shift  strontium optical lattice clock  optical lattice  spin-polarized spectrum   Solution of Green function from a moving line source and the radiation energy analysis : A simplified modeling of seismic signal induced by high-speed train 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2019, 卷号: 62, 期号: 6, 页码: 2303-2312 作者:  Cao Jian;  Chen JingBo   |  收藏  |  浏览/下载：64/0  |  提交时间：2019/07/29 Green function  High-speed train  Half and full space  Frequency-spectrum feature  Radiation directivity
