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.   Compression of correlation time of chirped biphotons by binary phase modulation 期刊论文  OAI收割 ACTA PHYSICA SINICA, 2017, 卷号: 66, 期号: 4 作者:  Li BH(李百宏);  Wang DD(王豆豆);  Pang HF(庞华锋);  Zhang T(张涛);  Jie Y(解忧)   |  收藏  |  浏览/下载：8/0  |  提交时间：2021/01/11 PARAMETRIC DOWNCONVERSION  2-PHOTON ABSORPTION  AXIAL RESOLUTION  GENERATION  ULTRABROADBAND  FLUORESCENCE  ENTANGLEMENT  ENERGY  LIGHT  chirped biphotons  correlation times  compression  binary phase modulation   Generation of a sub-diffraction hollow ring by shaping an azimuthally polarized wave 期刊论文  OAI收割 SCIENTIFIC REPORTS, 2016, 卷号: 6 作者:  Chen, Gang;  Wu, Zhi-Xiang;  Yu, An-ping;  Zhang, Zhi-hai;  Wen, Zhong-quan   |  收藏  |  浏览/下载：42/0  |  提交时间：2018/06/14 Super-oscillatory Lens  Cylindrical-vector Beams  Long Focal Length  Phase Modulation  Far-field  Light  Amplitude  Binary  Spot  Superresolution
