| 1 | A promising new class of irradiation tolerant materials:Ti_2ZrHfV_(0.5)Mo_(0.2) high-entropy alloy显示文摘Recently, high-entropy alloys(HEAs) or multi-principal-element alloys with unprecedented physical,chemical, and mechanical properties, have been considered as candidate materials used in advanced reactors due to their promising irradiation resistant behavior. Here, we report a new single-phase bodycentered cubic(BCC) structured Ti_2 ZrHfV_(0.5)Mo_(0.2) HEA possessing excellent irradiation resistance, i.e.,scarcely irradiation hardening and abnormal lattice constant reduction after helium-ion irradiation,which is completely different from conventional alloys. This is the first time to report the abnormal XRD phenomenon of metallic alloys and almost no hardening after irradiation. These excellent properties make it to be a potential candidate material used as core components in next-generation nuclear reactors. The particular irradiation tolerance derives from high density lattice vacancies/defects. | Yiping Lu Hefei Huang Xuzhou Gao Cuilan Ren Jie Gao Huanzhi Zhang Shijian Zheng Qianqian Jin Yonghao Zhao Chenyang Lu Tongmin Wang Tingju Li | 2019 | Journal of Materials Science & Technology2019，35，3： | 23 |
| 2 | Quantum secret sharing between multiparty and multiparty with Bell states and Bell measurements显示文摘We present a quantum secret sharing scheme between multiparty (m members in Group 1) and multiparty (n members in Group 2), and analyze its security. This scheme takes EPR pairs in Bell states as quantum resources. In order to obtain the shared key, all members only need to perform Bell measurements, rather than perform any local unitary operation. The total efficiency in this scheme approaches 100% as the classical information exchanged is not necessary except for the eavesdropping checks. | SHI RunHua 1,2* , HUANG LiuSheng 1,3 , YANG Wei 1,3 & ZHONG Hong 2 1 National High Performance Computing Center at Hefei, Department of Computer Science and Technology, University of Science and Technology of China, Hefei, 230027, China 2 School of Computer Science and Technology, Anhui University, Hefei 230039, China 3 Suzhou Institute for Advanced Study, USTC, Suzhou 215123, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，12： | 17 |
| 3 | Cellular automata pedestrian movement model considering human behavior显示文摘The pedestrian movement is more complex than vehicular flow for the reason that people are more flexible and intelligent than car. Without the limit of 搇anes?pedestrian movement is loose and free. Furthermore, they are easily affected by other walkers as well as the environ-ment around. In this paper some special technique is intro-duced considering human behavior to make the rules more reasonable. By simulating the two-dimension pedestrian movement, the phase transition phenomena of pedestrian movement, including the up walkers moving from the bottom to the upper boundary and the right walkers moving from the left to the right boundary, are presented. Studying on the effect of the system size on the critical density shows that the critical density is independent of the system size in the scope studied in this paper. | YANG Lizhong, FANG Weifeng, LI Jian, HUANG Rui & FAN Weicheng State Key Laboratory of Fire Science, University of Science and Tech-nology of China, Hefei 230026, China Correspondence should be addressed to Yang Lizhong (e-mail:zxd@ustc. edu.cn) | 2003 | Chinese Science Bulletin2003，48，16： | 16 |
| 4 | A blow-up criterion for classical solutions to the compressible Navier-Stokes equations显示文摘In this paper, we obtain a blow-up criterion for classical solutions to the 3-D compressible Navier-Stokes equations just in terms of the gradient of the velocity, analogous to the Beal-Kato-Majda criterion for the ideal incompressible flow. In addition, the initial vacuum is allowed in our case. | HUANG XiangDi 1 & XIN ZhouPing 2, 1 Department of Mathematics, University of Science and Technology of China, Hefei 230026, China 2 Department of Mathematics, The Chinese University of Hong Kong, Hong Kong, China | 2010 | Science China Mathematics2010，53，3： | 13 |

| 6 | Stratigraphy and TL Dating of Paleolithic Sites in the Luonan Basin,China显示文摘Between 1995 and 1999 the Longyadong cave site and 50 open air Paleolithic sites were investigated and excavated in the Luonan Basin of China. A total of 1?751 stone artifacts were collected from open air sites, and fossils from about 20 animal species as well as 65?000 lithic artifacts were excavated from the cave site. This paper provides a preliminary study of site lithic stratigraphics in their geological context as well as the results of thermoluminescence (TL) dating. The TL dates of five soil samples place the sites into the middle to late period of the Middle Pleistocene (Q 2 2—3 ). Upon further taking into account strata relationships, three cultural periods were identified in Longyadong cave. When compared with the TL dates and stratigraphy from Zhoukoudian Locality 1, loess deposits in Shaanxi Luochuan, red earth in Anhui and deep sea records, Longyadong is in the range of 500—250 kyr, approximately the same timeframe as Zhoukoudian Locality 1. | WANG She jiang(Shaanxi Provincial Institute of Archaeology, Xi’an, P.

| 7 | Application of rock creep experiment in calculating the viscoelastic parameters of earth medium显示文摘Based on the rock creep experiment, the data of aftershock sequence and post-earth- quake deformation are used to estimate the viscosity of crust medium near earthquake focus. Firstly 9 samples that belong to 3 kinds of rock are conducted in creep experiment under constant pressure to obtain the creep curves directly. Inversion results show that the standard linear model is the best one to present the earth medium. It exhibits obvious elasticity within a short time, while it exhibits obvious rheology within a long time. The relationship between element module μ 2 and the whole module μ of standard linear model or the module of real earth medium is calculated and analyzed. On the basis of μ 2 = 25 μ, the sequence of aftershock of Gonghe earthquake in Qinghai Province is analyzed and the relationship between accumulated released strain and the time is obtained, which, combined with the creep experiment results, is used to estimate the viscosity of crustal medium in this area. The measured vertical deformation after the same earthquake also is combined with the creep experiment results, then it is used to calculate the relaxation time and viscosity through three different methods respectively, i.e. inversion of Kelvin model, difference method of deformation and viscoelastic dislo- cation theory. The viscosity of crustal medium in 32 km depth of earthquake focus of Gonghe area deduced from the different data and methods is about 1019 Pa·s, which is the same as the research results by other authors at home and abroad. | SHI Xingjue1, WEN Dan1, BAO Xueyang1, LI Chengbo1 & HUANG Yun2 1.

| 9 | Effect of illumination intensity and light application time on secondary organic aerosol formation from the photooxidation of α-pinene显示文摘Secondary organic aerosol (SOA) formation from hydroxyl radical (OH.) initiated photooxidation of α-pinene was investigated in a home-made smog chamber. The size distribution of SOA particles was measured using aerodynamic particle sizer spectrometer. The effects of illumination intensity and light application time on SOA formation for α-pinene were evaluated. Experimental results show that the concentration of SOA particles increased significantly with an increasing of illumination intensity, and the light application time, the concentration, and the size of SOA particles were also increased. In addition, the factors influencing the formation of SOA were discussed. In addition, this article compared the effect of α-pinene with that of toluene, and discussed the contribution of α-pinene to SOA formation. | LIU Xianyun, ZHANG Weijun, HUANG Mingqiang, WANG Zhenya, HAO Liqing, ZHAO Wenwu Laboratory of Environment Spectroscopy, Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences,Hefei 230031, China. | 2009 | Journal of Environmental Sciences2009，21，4： | 7 |
| 10 | Dual Gabriel theorem with applications显示文摘We introduce the quiver of a bicomodule over a cosemisimple coalgebra. Applying this to the coradical C0 of an arbitrary coalgebra C, we give an alternative definition of the Gabriel quiver of C, and then show that it coincides with the known Ext quiver of C and the link quiver of C. The dual Gabriel theorem for a coalgebra with a separable coradical is obtained, which generalizes the corresponding result for a pointed coalgebra. We also give a new description of C1 = C0 ∧X C0 of any coalgebra C, which can be regarded as a generalization of the first part of the well-known Taft-Wilson Theorem for pointed coalgebras. As applications, we give a characterization of locally finite coalgebras via their Gabriel quivers, and a property of the Gabriel quiver of a quasi-coFrobenius coalgebra. | CHEN Xiaowu, HUANG Hualin & ZHANG Pu Department of Mathematics, University of Science and Technology of China, Hefei 230026, China USTC Shanghai Institute for Advanced Studies, Shanghai 201315, China Mathematical Section, the Abdus Salam ICTP, Strada Costiera 11, Trieste 34014, Italy Department of Mathematics, Shanghai Jiao Tong University, Shanghai 200030, China | 2006 | Science China Mathematics2006，49，1： | 6 |
| 11 | A high time resolution multi-gap resistive plate chamber显示文摘Research on a single cell Multi-gap Resistive Plate Chamber (MRPC) was carried out for the Time Of Flight detector (TOF) R and D of the STAR experi- ment. The property of the single chamber was tested with the test beam facility T10 at CERN in Geneva. The MRPC was scanned with the test beam to get the efficiency and time resolution at different position of the active area. The HV plateau was also measured. The time resolution is 65 ps which satisfies the requirement of STAR. The working mechanism of the MRPC is also explained. | LI Cheng, WU Jian, WANG Xiao-Lian, CHEN Hong-Fang, XU Zi-Zong, SHAO Ming, YE Shu-Wei, RUAN Li-Juan, HUANG Sheng-Li (Department of Modern Physics, University of Science and Technology of China, Hefei 230027) | 2002 | Nuclear Science and Techniques2002，13，1： | 5 |
| 12 | THERMAL CONDUCTIVITY OF THF CLATHRATE HYDRATE FROM 243 K TO 263 K显示文摘Using transient plane source technique, we measured THF hydrate thermal conductivity from 243 K to 263 K. The sample THF solution is over saturated in order to avoid the effect of ice. And also to avoid the effect of crystal anisotropy, the THF hydrate was crushed to measure.

| 13 | Hydrocarbon test in lower-layer atmosphere to predict deep-sea petroleum or hydrate in the Okinawa Trough: an example显示文摘Light hydrocarbon (methane, ethane, propane, butane and CO 2) test and C isotopic analysis of CO 2 are conducted for over 100 lower-layer atmospheric samples from the East China Sea slope and the Okinawa Trough. The results show that the lower-layer atmosphere mainly consists of CO 2 and then of CH 4, and the CO 2 concentrations are calculated to have a high average value of 0.87 ω/10 -2,about three times that of the regional background (0.3 ω/10 -2). The result also shows that the average value of C isotope -20.8×10 -3 is given to the CO 2, inferring that it is inorganic gas. Thus,for the future’s work in the Okinawa Trough, special attention should be paid to CO 2 hydrate, which is very possibly an important hydrate type. | Gong Jianming1, Chen Jianwen 1, 2, Li Gang1, Zhang Xunhua1, Li Jipeng3, Huang Fulin1 1.

| 14 | Fractionations of rare earth elements in plants and their conceptive model显示文摘Fractionations of rare earth elements (REEs) and their mechanisms in soybean were studied through application of exogenous mixed REEs under hydroponic conditions. Significant enrichment of middle REEs (MREEs) and heavy REEs (HREEs) was observed in plant roots and leaves respectively, with slight fractionation between light REEs (LREEs) and HREEs in stems. Moreover, the tetrad effect was observed in these organs. Investigations into REE speciation in roots and in the xylem sap using X-ray absorption spectroscopy (XAS) and nanometer-sized TiO2 adsorption techniques, associated with other controlled experiments, demonstrated that REE fractionations should be dominated by fixation mechanism in roots caused by cell wall absorption and phosphate precipitation, and by the combined effects of fixation mechanism and transport mechanism in aboveground parts caused by solution complexation by intrinsic organic ligands. A conceptive model was established for REE fractionations in plants based on the above studies. | DING ShiMing1,2, LIANG Tao2, YAN JunCai3, ZHANG ZiLi3, HUANG ZeChun2 & XIE YaNing4 1 Nanjing Institute of Geography & Limnology, Chinese Academy of Sciences, Nanjing 210008, China 2 Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China 3 Anhui Agricultural University, Hefei 230036, China 4 State Key Laboratory of Synchrotron Radiation, Institute of High Energy Physics, Chinese Academy of Sciences, Beijing 100039, China | 2007 | Science China(Life Sciences)2007，50，1： | 4 |
| 15 | Admission Control with Elastic QoS for Video on Demand Systems显示文摘In network service systems, satisfying quality of service (QoS) is one of the main objectives. Admission control and resource allocation strategy can be used to guarantee the QoS requirement. Based on partially observable Markov decision processes (POMDPs), this paper proposes a novel admission control model for video on demand (VOD) service systems with elastic QoS. Elastic QoS is also considered in resource allocation strategy. Policy gradient algorithm is often available to find the solution of POMDP problems, with a satisfactory convergence rate. Through numerical examples, it can be shown that the proposed admission control strategy has better performance than complete admission control strategy. | Fu-Shou Lin 1 Bao-Qun Yin 1,2 Jing Huang 1 Xu-Min Wu 1 1 Key Lab of Anhui Network Communication System and Control, University of Science and Technology of China, Hefei 230027, China 2 National Network New Media Engineering Research Center, Institute of Acoustics, Chinese Academy of Science, Beijing 100190, China | 2012 | International Journal of Automation and computing2012，9，5： | 3 |

Their one-and two-photon absorption (TPA) and excited fluorescence properties have been experimentally investigated. The two-photon absorption cross-sections of two compounds were estimated by two-photon excited fluorescence technique using 200 fs, 76 MHz, Ti:sapphire laser, which are 22 and 154 GM for BCSPC and BCPBC, respectively. The optimal excitation wavelengths are 780 nm for both BCSPC and BCPBC. A data recording experiment proved the potential application of the materials. | LI Lin1, YANG JiaXiang1,2, WANG CaiXia1, HU ZhangJun1, TIAN YuPeng1,2, LI Jing3, WANG ChuanKui3, LI Ming4, CHENG GuangHua4, TANG HuoHong5, HUANG WenHao5, TAO XuTang2 & JIANG MinHua2 1Department of Chemistry, Anhui University, Hefei 230039, China 2State Key Laboratory of Crystal Materials, Institute of Crystal Materials of Shandong University, Jinan 250100, China 3Department of Physics, Shandong Normal University, Jinan 250014, China 4State Key Laboratory of Transient Optics and Photonics, Xi’an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, Xi’an 710119, China 5Department of Precision Machinery and Precision Instrumentation, University of Science and Technology of China, Hefei 230026, China | 2010 | Science China Chemistry2010，53，4： | 2 |
| 17 | Electric Field Effects on Animals:Mechanism of Seismic Anomalous Animal Behaviors (SAABs)显示文摘Electric field effect on animals has been studied to investigate its relation with seismic anomalous animal behaviors(SAABs)in China.Freshwater eel,crucian carp,catfish,and soft-shelled turtle responded to the threshold electric field of 1-10 V/m,while duck,goose,cat,sheep,pig,dog,and chicken all responded to the ground electric field of about tens of V/m,depending on the species as well as on individuals.Most of the behaviors caused by electric field were similar to those reported as SAABs such as alignment,sudden movement,panic,and convulsion.The intensity of electric field due to a major earthquake would have been over these threshold values.Numerical estimation based on an electromagnetic model of a fault has been made to induce SAABs as electric shocks to pulsed electric fields in electro-physiology.The seismic electric signals(SES)intensity might be estimated from the observation of SAABs. | Huang Qinghua,Ikeya Motoji,and Huang PeihuaDepartment of Earth and Space Sciences,Graduate School of Science,Osaka University,Osaka 560,Japan Department of Earth and Space Sciences,University of Science and Technology of China,Hefei 230026,China | 1997 | Earthquake Research in China1997，11，1： | 1 |
| 18 | A potential candidate structural material for molten salt reactor:ODS nickel-based alloy显示文摘The commercialisation of molten salts reactors(MSRs)is hindered by the lack of structural materials capable of withstanding the corrosive environment therein.To address this problem,we herein prepared1 wt%Y_(2)O_(3)mdispersion-strengthened Ni Mo-based alloys using powder metallurgy and evaluated their potential as structural materials for MSRs based on their mechanical properties,He swelling behaviour,and molten salt corrosion resistance.In view of the strengthening provided by homogenously dispersed Y_(2)O_(3)particles,all NiMo-Y_(2)O_(3)samples exhibited ultimate tensile strengths and yield strengths exceeding those of the Hastelloy N alloy,a state-of-the-art structural material for MSRs.Moreover,the volume fraction of He bubbles in the NiMo-Y_(2)O_(3)samples(~0.3%)was lower than that in the Hastelloy N alloy(0.58%),which showed that the introduction of Y_(2)O_(3)nanoparticles effectively inhibited He swelling.All NiMo-Y_(2)O_(3)samples showed excellent resistance to molten salt corrosion(as reflected by the absence of obvious holes therein),thus holding great promise for the development of irradiation-and molten salt corrosion-resistant structural materials for high-temperature MSRs. | Cheng Li Guanhong Lei Jizhao Liu Awen Liu CLRen Hefei Huang | 2022 | Journal of Materials Science & Technology2022，，14： | 1 |
