| 1 | The Lobster Eye Imager for Astronomy Onboard the SATech-01 Satellite显示文摘The Lobster Eye Imager for Astronomy(LEIA),a pathfinder of the Wide-field X-ray Telescope of the Einstein Probe mission,was successfully launched onboard the SATech-01 satellite of the Chinese Academy of Sciences on2022 July 27.In this paper,we introduce the design and on-ground test results of the LEIA instrument.Using stateof-the-art Micro-Pore Optics(MPO),a wide field of view of 346 square degrees(18.6°×18.6°)of the X-ray imager is realized.An optical assembly composed of 36 MPO chips is used to focus incident X-ray photons,and four large-format complementary metal-oxide semiconductor(CMOS)sensors,each of size 6 cm×6 cm,are used as the focal plane detectors.The instrument has an angular resolution of 4’-8’(in terms of FWHM)for the central focal spot of the point-spread function,and an effective area of 2-3 cm^(2) at 1 keV in essentially all the directions within the field of view.The detection passband is 0.5-4 keV in soft X-rays and the sensitivity is2-3×10^(-11) erg s^(-1) cm^(-2)(about 1 milliCrab)with a 1000 s observation.The total weight of LEIA is 56 kg and the power is 85 W.The satellite,with a design lifetime of 2 yr,operates in a Sun-synchronous orbit of 500 km with an orbital period of 95 minutes.LEIA is paving the way for future missions by verifying in flight the technologies of both novel focusing imaging optics and CMOS sensors for X-ray observation,and by optimizing the working setups of the instrumental parameters.In addition,LEIA is able to carry out scientific observations to find new transients and to monitor known sources in the soft X-ray band,albeit with limited useful observing time available. | Z.X.Ling X.J.Sun C.Zhang S.L.Sun G.Jin S.N.Zhang X.F.Zhang J.B.Chang F.S.Chen Y.F.Chen Z.W.Cheng W.Fu Y.X.Han H.Li J.F.Li Y.Li Z.D.Li P.R.Liu Y.H.Lv X.H.Ma Y.J.Tang C.B.Wang R.J.Xie Y.L.Xue A.L.Yan Q.Zhang C.Y.Bao H.B.Cai H.Q.Cheng C.Z.Cui Y.F.Dai D.W.Fan H.B.Hu J.W.Hu M.H.Huang Z.Q.Jia C.C.Jin D.Y.Li J.Q.Li H.Y.Liu M.J.Liu Y.Liu H.W.Pan Y.L.Qiu M.Sugizaki H.Sun W.X.Wang Y.L.Wang Q.Y.Wu X.P.Xu Y.F.Xu H.N.Yang X.Yang B.Zhang M.Zhang W.D.Zhang Z.Zhang D.H.Zhao X.Q.Cong B.W.Jiang L.H.Li X.B.Qiu J.N.Sun D.T.Su J.Wang C.Wu Z.Xu X.M.Yang S.K.Zhang Z.Zhang N.Zhang Y.F.Zhu H.Y.Ban X.Z.Bi Z.M.Cai W.Chen X.Chen Y.H.Chen Y.Cui X.L.Duan Z.G Feng Y.Gao J.W.He T.He J.J.Huang F.Li J.S.Li T.J.Li T.T.Li H.Q.Liu L.Liu R.Liu S.Liu N.Meng Q.Shi A.T.Sun Y.M.Wang Y.B.Wang H.C.Wu D.X Xu Y.Q Yang Y.Yang X.S.Yu K.X.Zhang Y.L.Zhang Y.H.Zhang Y.T.Zhang H.Zhou X.C.Zhu J.S.Cheng L.Qin L.Wang Q.L.Wang M.Bai R.L.Gao Z.Ji Y.R.Liu F.L.Ma Y.J.Shi J.Su Y.Y.Tan J.Z.Tong H.T.Xu C.B.Xue G.F.Xue W.Yuan | 2023 | Research in Astronomy and Astrophysics2023，23，9： | 2 |

| 9 | Analysis of heat transfer processes for sapphire growth by horizontal directed crystallization method显示文摘This research summarizes the analytical and experimental results of heat-transfer processes influence on defects formation during sapphire crystal growth by horizontal directed crystallization method(HDC).The shape of solid-melt interface significantly influences the process of sapphire crystals growth by this method.We receive the Stefan problem solution for sapphire crystals growth.It allows investigating the crystal growth process and the related factors(thermal stresses on different stages of growth process),their influence on defects formation.We investigate the main reasons for the formation of defective structures of the solid phase of sapphire crystals and the influence of thermal unit construction,the crystal geometry on the quality of the resulting sapphire crystal.We study the structure formation process,impurity distribution,and the nature of the defects in the crystal during it growth. | Yu.V.Klunnikova S.P.Malyukov A.V.Filimonov N.Zhang | 2020 | Journal of Advanced Dielectrics2020，10，1： | 0 |

| 11 | Applicability of large-ion lithophile and high field strength element basalt discrimination diagrams显示文摘Basalt discriminant diagrams have been used to identify the tectonic setting of basaltic magmatism since the 1970s and have played an important role in reconstructing paleotectonic environments.However,the significant increase in the availability of geochemical data has led to a reassessment of these diagrams,suggesting that some of the tectonic settings indicated by these diagrams are not accurate.Here,we use a database of global ocean island basalt(OIB),mid-ocean ridge basalt(MORB),and island arc basalt(IAB)geochemistry to propose a series of new tectonic discriminant diagrams based on the ratios of large-ion lithophile elements(LILEs)to high field strength elements(HFSEs).These new diagrams indicate that the LILE can be used to differentiate OIB,MORB,and IAB samples,meaning that LILE/HFSE ratios can discriminate between these basalts that form in different tectonic settings.Our new diagrams can correctly assign samples to OIB,MORB,and IAB categories more than 85%of the time,with the discrimination between OIB and MORB having an accuracy of slightly less than 85%. | X.L.Liu Q.Zhang W.C.Li F.C.Yang Y.Zhao Z.Li S.T.Jiao J.R.Wang N.Zhang S.S.Wang W.F.Chen Z.J.Pan J.Yang X.L.Du | 2018 | International Journal of Digital Earth2018，11，7： | 0 |
