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.   XUV pulse effect on signal modulations of harmonic spectra from H-2(+) and T-2(+) 期刊论文  OAI收割 PRAMANA-JOURNAL OF PHYSICS, 2018, 卷号: 90, 期号: 5 作者:  Liu, Hang;  Feng, April Y.;  Feng, Liqiang;  Kapteyn, Henry J.   |  收藏  |  浏览/下载：30/0  |  提交时间：2019/06/20 Molecular High-order Harmonic Generation  Amplitude Modulation Of Harmonics  Frequency Modulation Of Harmonics  Multiplateau Structure  Xuv Pulse   Doppler-robust high-spectrum-efficiency VCM-OFDM scheme for low Earth orbit satellites broadband data transmission 期刊论文  OAI收割 IET COMMUNICATIONS, 2018, 卷号: 12, 期号: 1, 页码: 35-43 作者:  Li, Jionghui;  Xiong, Weiming;  Sun, Geng;  Wang, Zhugang;  Huang, Yonghui   |  收藏  |  浏览/下载：74/0  |  提交时间：2018/03/02 Satellite Ground Stations  Satellite Links  Radio Receivers  Radio Transmitters  Ofdm Modulation  Modulation Coding  Doppler Shift  Filtering Theory  Doppler-robust High-spectrum-efficiency Vcm-ofdm Scheme  Low Earth Orbit Satellites Broadband Data Transmission  High-efficiency Satellite-ground Downlink Data Transmission System  Limited Spectrum Resource  Dynamic Link Conditions  Orbital Motion  Leo Satellite  Variable Coding Modulated Orthogonal Frequency Division Multiplexing  Satellite On-board Transmitter  Ground Station Receiver  Filtered-ofdm Signal  Adjustable Codmod  Spectral Efficiency  Physical Layer Frame Structure  Doppler Frequency Shift Compensation  Future Gigabit X-band Reliable Satellite-ground Downlink Transmissions   XUV pulse effect on harmonic emission spectra and attosecond pulse generation 期刊论文  OAI收割 MODERN PHYSICS LETTERS B, 2017, 卷号: 31, 期号: 34 作者:  Feng, Liqiang;  Castle, R.
