We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

川南地区上奥陶统五峰组-下志留统龙马溪组黑色页岩层系是我国南方海相页岩气勘探开发最具代表性和示范性的地区,但其油气成藏过程及特征研究相对薄弱.基于含油气系统成藏动力学过程的基本原理,结合量化构造地质学、低温热年代学和盆地数值模拟等研究,以多期构造变形过程中五峰组-龙马溪组生烃动力学及其压力体系变化特征为载体,实现对其成藏过程的模拟表征和再现.以川南长宁页岩气田五峰组-龙马溪组页岩层系为研究对象,流体包裹体测试揭示其均一温度呈双峰分布特征,分别为120~140℃和160~180℃,捕获压力压力系数为1.0~1.1和1.1~1.3;低温热年代学定年和热史模拟揭示该区新生代地表抬升剥蚀量达2.0~2.5 km,五峰组-龙马溪组页岩热史模拟表明,中志留纪-中二叠世、晚二叠世-晚三叠世、早侏罗世-早白垩世和早白垩世以来烃源岩分别进入低成熟、中等成熟、高成熟和过成熟阶段.压力模拟结果显示,长宁地区五峰组-龙马溪组页岩层系早期长时间属于常压系统,至晚侏罗世地层持续埋深增温导致五峰组-龙马溪组生气速率达到高峰,地层压力剧增,逐步形成超压,早-中白垩世埋深达到最大,地层压力系数达2.0左右,新生代地表虽然遭受抬升剥蚀作用,但五峰组-龙马溪组超压被保存下来,现今压力系数仍有1.9.因此,川南地区长宁五峰组-龙马溪组页岩气田具有早期有限聚集、中晚期富集-保存超压型成藏特征.

The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main *** of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator *** this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/*** ten years of data acquisition,approximately 60,000 signal and 30,000 background events are *** large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation *** m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith ***,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.
