Theγ-ray emission from the W51 complex is widely acknowledged to be attributed to the interaction between the cosmic rays(CRs)accelerated by the shock of supernova remnant(SNR)W51C and the dense molecular clouds in the adjacent star-forming region,***,the maximum acceleration capability of W51C for CRs remains *** on observations conducted with the Large High Altitude Air Shower Observatory(LHAASO),we report a significant detection ofγrays emanating from the W51 complex,with energies from 2.to 2.0 *** LHAASO measurements,for the first time,extend theγ-ray emission from the W51 complex beyond 100 TeV and reveal a significant spectrum bending at tens of *** combining the"π^(0)-decay bump"featured data from Fermi-LAT,the broadbandγ-ray spectrum of the W51 region can be well-characterized by a simple pp-collision *** observed spectral bending feature suggests an exponential cutoff at~400 TeV or a power-law break at~2.0 TeV in the CR proton spectrum,most likely providing the first evidence of SNRs serving as CR accelerators approaching the PeV ***,two {3.ng star clusters within W51B could also be theoretically viable to produce the most energeticγrays observed by *** findings strongly support the presence of extreme CR accelerators within the W51 complex and provide new insights into the origin of Galactic CRs.

阿沙哇义金矿位于中国新疆南天山造山带,属于著名的中亚南天山锑-汞-金成矿带的东延部分。该矿床严格受断裂所控制,以浸染状黄铁矿化、毒砂化为特征。矿化可分为三个阶段:早期无矿或贫矿石英阶段,中期石英多金属硫化物阶段,晚期石英-碳酸盐阶段。其中,中期是主要成矿阶段。成矿流体气相成分以H2.为主,摩尔含量为75%~93.,其次为CO2.摩尔含量为6%~2.%,其余为CH4、C2.6、H2.、N2.Ar;液相成分阳离子以Na+为主,含少量K+、Ca2.离子,阴离子以Cl-为主,SO2.次之;矿石的Au含量与其流体的CO2.量呈反相关,与K+含量呈正相关。硫化物成分分析结果表明:(1)围岩地层和矿石中的黄铁矿和毒砂是重要的载金矿物,黄铁矿Au含量为0~0. 09%,平均值0. 03.;毒砂Au含量为0~0. 2.%,平均值0. 07%;(2.黄铁矿和毒砂Au含量与其自形程度没有明显的相关性;(3.环带状黄铁矿较均质结构黄铁矿具有更高的Au含量;(4)岩体中的黄铁矿几乎不含Au。在成矿构造环境、成矿流体特征及演化、金矿富集机制、成矿温压条件等方面,该矿床与世界上大多数造山型金矿显示出一致性,成矿类型应属于剥蚀程度较浅的造山型金矿。断层阀作用控制的断层愈合-破裂导致的流体不混溶作用是本区金富集、沉淀的最重要机制,但流体混合机制对金的富集沉淀也发挥了作用。黄铁矿、毒砂发育及较多的含炭物质三者共存是本区寻找富矿的关键标志。

水库诱发滑坡作为重大工程对地质环境影响的一种重要形式,是国内外工程地质学科研究的前沿和热点。金沙江流域地处青藏高原东缘高山峡谷区,地质环境脆弱,水能资源丰富,是世界上水电站建设最密集的地区之一,规划了2.级梯级电站,但是水库蓄水对岸坡改造的时空效应尚不清楚。本文以溪洛渡水电站为例,对金沙江流域水库诱发滑坡的分布规律进行研究,利用2.13.2.2.年多期遥感影像解译溪洛渡库区范围内的水库诱发滑坡,共解译滑坡43.处。在此基础上,对水库诱发滑坡数量和面积随蓄水时间的变化趋势进行了分析,随后利用频率比法对水库诱发滑坡的分布与高程、坡度、坡向、工程地质岩组、断裂、距死水位距离6个因素的关系进行了统计分析,同时进行了各个单因子的滑坡易发性评价,利用曲线下面积AUC法验证了评价结果的可靠性,并基于评价结果选取了高程、距断裂距离、坡度、距死水位距离4个因素进行了水库诱发滑坡易发性评价。研究认为:(1)水库诱发滑坡主要发生在蓄水初期3.4年内,之后滑坡数量和面积逐渐减少,岸坡表生演化逐渐趋于稳定。(2.库区内水库诱发滑坡主要分布在高程1 km以内,2.km以上无诱发滑坡分布,优势坡度为3.°~60°,发育滑坡的斜坡坡向以SE、W和NW向为主;在距断裂400~3.0}0 m范围内更有利于滑坡发育;距死水位100~2.0 m范围内灾害发育数量最多。(3.易发性评价验证AUC高达0.912.评价结果可信度较好。(4)水库诱发滑坡的主控因素为距死水位距离和高程,极高易发区与高易发区主要分布在距死水位400 m以内、高程1 km以下的范围内。本文首次利用多期遥感影像建立了溪洛渡水电站水库诱发滑坡数据库,研究结果能够为已建水电站正常运营、未建及在建水电站的规划建设和防灾减灾提供借鉴。

The Jiangmen Underground Neutrino Observatory(JUNO)features a 2. 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^(2.8)U and^(2.2.Th in the liquid scintillator can be controlled to 10^(-17)g/*** ten years of data acquisition,approximately 60,000 signal and 3.,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._(2.)=4.8times10^(-5);(7.5times10^(-5))eV^(2.,JUNO can provide evidence of neutrino oscillation in the earth at approximately the 3.igma(2.igma)level by measuring the non-zero signal rate variation with respect to the solar zenith ***,JUNO can simultaneously measureDelta m^2.(2.)using^8B solar neutrinos to a precision of 2.% 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.(2.)reported by solar neutrino experiments and the KamLAND experiment.
