The evolution of intensity, hardness and integrated fractional root mean square (rms) observed by Insight-HXMT and NICER are presented in this paper. Type-C quasi-periodic oscillations (QPOs) observed by NICER (0.8-3.5 Hz) and Insight-HXMT (1-1.6 Hz) are also reported in this work. The features of the QPOs are analyzed with an energy range of 0.5-50 keV. The relations between QPO frequency and other characteristics such as intensity, hardness and QPO rms are carefully studied. The timing and spectral properties indicate that Swift J1658.2-4242 is a black hole binary system. Besides, the rms spectra of the source calculated from the simultaneous observation of Insight-HXMT, NICER and AstroSat support the Lense-Thirring origin of the QPOs. The relation between QPO phase lag and the centroid frequency of Swift J1658.2-4242 reveals a near zero constant when < 4Hz and a soft phase lag at 6.68 Hz. This independence follows the same trend as the high inclination galactic black hole binaries such as MAXI J1659-152.   中小型球面反射镜柔性支撑优化设计 期刊论文  OAI收割 长春理工大学学报(自然科学版), 2019, 卷号: 42, 期号: 03, 页码: 7-10 作者:  王文攀;  吕天宇;  刘祥意;  范磊   |  收藏  |  浏览/下载：67/0  |  提交时间：2020/08/24 双曲面反射镜  柔性支撑  有限元分析  面型精度RMS   Evaluation of the Klobuchar model in TaiWan 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2017, 卷号: 60, 期号: 6, 页码: 1210-1219 作者:  Fan, Jiangtao;  Li, Jinghua;  Wan, Qingtao;  Ma, Guanyi;  Zhang, Jie   |  收藏  |  浏览/下载：45/0  |  提交时间：2017/12/06 Ionospheric Model  Residual  Tec  Rms Correction  Klobuchar Model  Solar Activity   A NONLINEAR OPTIMIZATION ALGORITHM FOR EVALUATING THE PERFORMANCE OF MICROWAVE IMAGER COMBINED ACTIVE/PASSIVE 会议论文  OAI收割 Fort Worth, TX, JUL 23-28, 2017 作者:  Zhang, Lan-jie;  Wang, Zhen-zhan;  Zhang, Ruan-yu;  Yin, Xiao-bin   |  收藏  |  浏览/下载：27/0  |  提交时间：2018/05/04 Micap  Nonlinear Optimization Algorithm  Sss  Rms Error   Matched multi-trace geometry repeatability for time lapse seismic 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2016, 卷号: 59, 期号: 8, 页码: 3056-3067 作者:  Dong Feng-Shu;  Fu Li-Yun;  Quan Hai-Yan;  Dong Ke-Tong   |  收藏  |  浏览/下载：32/0  |  提交时间：2017/11/22 Time-lapse seismic  Normalized rms difference  Multi-trace repeatability  Best baseline-based match
