| 1 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 3 | Wavelength dimensioning for wavelength-routed WDM satellite network显示文摘Internet and broadband applications driven by data traffic demand have become key drivers for satellite constellations.The key technology to satisfy the high capacity requirements between satellites is optical satellite networks by means of wavelength division multiplexing intersatellite links(ISLs) with wavelength routing(WDM-OSN).Due to the limited optical amplifier bandwidth onboard the satellite,it is important to minimize the wavelength requirements to provision requests.However,ISLs should be dynamically established and deleted for each satellite according to its visible satellites.Furthermore,different link assignments will result in different topologies,hence yielding different routings and wavelength assignments.Thus,a perfect match model-based link assignment scheme(LAS-PMM) is proposed to design an appropriate topology such that shorter path could be routed and less wavelengths could be assigned for each ISL along the path.Finally,simulation results show that in comparison to the regular Manhattan street network(MSN) topology,wavelength requirements and average end-to-end delay based on the topology generated by LAS-PMM could be reduced by 24.8% and 12.4%,respectively. | Liu Zhe Guo Wei Deng Changlin Hu Weisheng | 2016 | Chinese Journal of Aeronautics2016，29，3： | 6 |

| 5 | Influence of Atmospheric Refraction on Horizontal Angle Surveying显示文摘Side-refraction is the main error source of horizontal angle surveying, but it has little influence on the sides by analyzing the influence of atmospheric-infraction on the ultrahigh-precision side and angle surveying. Choosing oriented direction is crucial to distance and angle measurement in triangulateration network. How to select the oriented direction during angle measurement is presented, and the means to check the quality of auto-surveying with Georobot is brought forward as well. At last some solutions to reduce the influence of side-refraction while disposing and surveying ultrahigh-precision triangulateration network are put forward. | ZHANG Zhenglu DENG Yong LUO Changlin MEI Wensheng | 2006 | Geo-Spatial Information Science2006，9，3： | 3 |

| 10 | Orange-red emitting Sr_3LaTa_3O_(12):Sm^(3+) phosphors with perovskite structure and high thermal stability for w-LEDs显示文摘A novel layered perovskite tantalate phosphor Sr_(3)LaTa_(3)O_(12):Sm^(3+)(SLTO:Sm^(3+)) with orange-red emission was obtained for the first time via the solid-phase synthetic method. The phase purity, surface morphology,element distribution and luminescent properties of the SLTO:xSm^(3+)(x= 0.01 mol%-0.30 mol%) phosphors were investigated. Under 408 nm excitation, the optimum doped SLTO:0.10Sm^(3+) phosphor emits orangered light at 598 nm with the highest emission peak(4G_(5/2)→6H_(7/2)). The critical energy transfer distance is 1.687 nm. The prepared SLTO:0.10Sm^(3+)phosphor has excellent thermal stability with temperature quenching temperature(T_(0.5)> 500 K) and high activation energy(E_(a)= 0.25 e V). Through calculation, the chromaticity coordinates of all samples are concentrated in the orange-red area, and the color purity reaches 99%. The fabricated white light-emitting diode(w-LED) has a good correlated color temperature(5132 K), a high R_(a)(89), and the CIE chromaticity coordinates(0.340, 0.327). Consequently, the superiority of orange-red-emitting tantalate SLTO:Sm^(3+) phosphors for w-LEDs is demonstrated. | Xiaopeng Hu Anlin Zhang Yufeng Du Li Zhou Changlin Li Jingjing Lian Zhequan Zou Xuan Ouyang Bin Deng Lianwu Xie Ruijin Yu | 2024 | Journal of Rare Earths2024，42，3： | 0 |

| 12 | Remote sensing detection and verification of disappeared reservoirs along the Grand Canal of China显示文摘Digital Earth is an information-rich expression of the real Earth and is a new way of understanding the Earth in the twenty-first century.Archeology has found great potentialities in Digital Earth,strongly increasing its development and its interdisciplinary experimentations.With the rapid development of remote sensing,the importance of applying Earth observation technology to archeological research has caught a great amount of attention worldwide.The objective of this study is to apply Radarsat-1 and Landsat imagery,historical maps,and aerial photographs in the detection and verification of disappeared reservoirs built 500 years ago as part of the Grand Canal of China.The results of the study show that the potential sites present distinct variations in soil moisture,biomass,and biological vigor,characterized by weak backscattering in Radarsat imagery;high vegetation indices in Landsat imagery;and distinct anomalies in a Landsat principle components image.Historical maps and aerial photographs also verified the existence of the sites of disappeared reservoirs.Since the sites have so far not been extensively explored,the results should represent a significant contribution to the understanding of the Grand Canal of China and its auxiliary facilities. | Biao Deng Yueping Nie Huadong Guo Changlin Wang Shenglin Lei Rong Li | 2013 | International Journal of Digital Earth2013，6，3： | 0 |
