| 1 | The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations. | Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 7 |
| 2 | Removal of heavy metals from mine water by cyanobacterial calcification显示文摘The influence of different illumination intensities on cyanobacterial calcification induced removal of heavy metals from contaminated mine water was studied. Cyanobacterial calcification experiments were performed using a growth medium intended to simulate contaminated mine water. The results indicate that calcification can promote the removal of heavy metal ions. As the illumination intensity became stronger calcification rates increased and the removal of Zn2+ and Cd2+ became more obvious. When the illumination intensity was 10000 lux the removal of Pb2+ was the largest observed: stronger or weaker illumination reduced the amount of lead removed. The removal of three different heavy metals complies with an index function. For identical illumination intensities different ions were removed to different degrees. | DONG Donglin LI Hongjiang ZHANG Jie SUN Luke | 2010 | Mining Science and Technology2010，20，4： | 5 |
| 3 | THE DISTRIBUTION OF PREFERENTIAL PATHS AND ITS RELATION TO THE SOIL CHARACTERISTICS IN THE THREE GORGES AREA,CHINA显示文摘To study the characteristics of the distribution of the preferential paths and the affecting factors in the Three Gorges area, four soil profiles were dug to observe the distribution of preferential paths in the Quxi watershed in the Yangtze River basin. The Morisita exponential test method was used to examine the distribution type of preferential paths. The physical properties and infiltration characteristics of the soil were also measured to evaluate their relationship to preferential paths. The results showed that in this area, preferential paths clustered and mainly distributed in the 80-100 cm soil layer, and along the interface between the weathered layer and semi-weathered layer. There were more non-capillary pores in the 83-110 cm layer than in the other layers. It can be derived that most non-capillary pores in this layer were preferential paths caused by geological processes and rotten plant roots. The percentage of coarse soil particles increased with the depth of the soil layer. In the deeper soil layer, the coarse soil particles helped the formation of preferential paths. The fastest steady infiltration rate was observed in the of 83-110cm layer, which is inferred to be due to the greater number of preferential paths. | Hongjiang ZHANG Jinhua CHENG Yuhu SHI Yun CHENG | 2007 | International Journal of Sediment Research2007，22，1： | 4 |
| 4 | Regional Prediction of Impending Debris Flow Based on Doppler Weather Radar显示文摘Debris flow prediction is one of the important means to re-duce the loss caused by debris flow. This paper built a regional predic-tion model of impending debris flow based on regional environmental background(including topography,geology,land use,and etc.) ,rainfall and debris flow data. A system of regional prediction of impending de-bris flow was set up on ArcGIS 9.0 platform according to the model. The system used forecast precipitation data of Doppler weather radar and observational precipitation data as its input data. It could provide a prediction about the possibility of debris flow one to three hours before it happened,and was put into use in Liangshan Meteorological Obser-vatory in Sichuan province in the monsoon of 2006. | JIANG Yuhong WEI Fangqiang ZHANG Jinghong GU Linkang DENG Bo LIU Hongjiang | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 3 |
| 5 | Improved Plasticity and Cold-rolling Workability of Fe–6.5wt%Si Alloy by Warm-rolling with Gradually Decreasing Temperature显示文摘The effects of warm-rolling process on the microstructure,ordering,mechanical properties and coldrolling workability of Fe–6.5wt%Si alloy were investigated,where three processes of warm-rolling with the same total reduction of 93% were used,including(1)500°C/12 passes/total reduction of 93%,(2)500°C/3passes/total reduction of 50%+400°C/9 passes/total reduction of 86%,and (3)500°C/3 passes/total reduction of 50%+400°C/5 passes/total reduction of 60%+300°C/4 passes/total reduction of 64%.The results show that compared with process (1) warm-rolling with constant temperature of 500°C,process(2) and process (3) warm-rolling with gradually decreasing temperature can signi?cantly improve the room temperature plasticity and cold-rolling workability of the Fe–6.5wt%Si alloy.For example,the three point bending fracture deflections are increased by 54.5% and 81.8% for processes (2) and (3),respectively,and the maximum reductions of single pass cold-rolling without edge crack are increased from 50% of process(1)to 55% of process (2) and 62% of process(3),respectively.The plasticity improvement of the Fe–6.5wt%Si alloy can be attributed to both reductions of surface oxidation degree and order degree of the alloy by warm-rolling with gradually decreasing temperature. | Yuanke Mo Zhihao Zhang Hongjiang Pan Jianxin Xie | 2016 | Journal of Materials Science & Technology2016，32，5： | 3 |
| 6 | Accelerating column leaching trial on copper sulfide ore显示文摘The main measures to accelerate leaching sulfide ore are large spraying intensity,manual oxygen supply,temperature control,and acclimated bacteria.The indoor experiment accelerating sulfide ore leaching detected the temperature during leaching process,dissolvability of oxygen,bacterial concentration,Cu concentration and slag grade.At the same time,this paper also analyzed the effect of four factors,which are bacterial diversity cultivation stage,spraying intensity,air supply,and whether to control temperature,on the leaching efficiency of copper.The results indicate that the oxygen content of leach solution has a close relationship with temperature but it is rarely affected by air supply.The bacterial concentration preserves from 106 to 107 mL-1,and temperature has a great effect on the bacterial activity under the condition of proper temperature and oxygen supply,and the lack of nutrition prevents the bacterial concentration from rising in the late stage.The relationships of the copper leaching efficiency to temperature,air feed,and spraying intensity are directly proportional.The leaching efficiencies of the cultivated bacteria and acclimation bacteria are 1.2 and 1.4 times as large as that of the original bacteria. | WANG Hongjiang WU Aixiang ZHOU Xun WANG Shaoyong ZHANG Jie | 2008 | Rare Metals2008，27，1： | 2 |
| 7 | In vitro antibacterial and osteogenic properties of plasma sprayed silver-containing hydroxyapatite coating显示文摘The objective of the present investigation was to characterize the antibacterial and osteogenic properties of plasma sprayed silver-containing hydroxyapatite (HA/Ag) coating in vitro. HA/Ag coating was deposited via vacuum plasma spraying. The concentration of silver ions released from HA/Ag coating, the efficacy of the HA/Ag coating against bacterial biofilm development, the effect of the HA/Ag coating on early adhesion and ossification of osteoblast cells in vitro was measured. The silver ion concentration released from the HA/Ag coating was between the minimum inhibitory concentration to bacteria and the cytotoxic concentration. Bacterial biofilm inhibition studies indicated an antibacterial activity on the HA/Ag coating surface when compared with hydroxyapatite (HA) coating alone. Moreover, it was demonstrated that osteoblast cell adhesion and mineralization occurred on the HA/Ag coating surface during the testing period. We conclude that the vacuum plasma sprayed HA/Ag coating possesses good antibacterial capability and osteogenic properties in vitro and represents a promising candidate for coating orthopedic implants. | RUAN HongJiang FAN CunYi ZHENG XueBin ZHANG Yan CHEN YiKai | 2009 | Chinese Science Bulletin2009，54，23： | 2 |
