| 1 | Single-phase high-entropy intermetallic compounds(HEICs): bridging high-entropy alloys and ceramics显示文摘High-entropy intermetallic compounds(HEICs)were fabricated by mechanical alloying and spark plasma sintering to fill a knowledge gap between the traditional high-entropy alloys(HEAs)and emerging highentropy ceramics(HECs).Notably,several four-or five-component equimolar aluminides,such as the B2-phase(Fe1/5 Co1/5 Ni1/5 Mn1/5 Cu1/5)Al,have been made into single-phase HEICs for the first time.Thermodynamic modeling and a reversible,temperature-dependent,phase-stability experiment suggest that such B2-phase HEICs are entropy-stabilized phases.The structure of these HEICs resembles that of HECs with high-entropy mixing of fo ur or five elements of nearly equal fractions in one and only one sublattice,but with significant(10%)anti-site defects(differing from typical HECs).A new phase stability rule for forming single B2-phase HEICs is proposed.Five additional HEICs of predominantly D022 phases have also been made.This study broadens the families of equimola r,single-phase,high-entropy materials that have been successfully fabricated. | Naixie Zhou Sicong Jiang Timothy Huang Mingde Qin Tao Hu Jian Luo | 2019 | Science Bulletin2019，64，12： | 8 |
| 2 | 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 |
| 3 | Calibration procedures for the CHASE/HIS science data显示文摘The Hα line is an important optical line in solar observations containing the information from the photosphere to the chromosphere. To study the mechanisms of solar eruptions and the plasma dynamics in the lower atmosphere, the Chinese Hα Solar Explorer(CHASE) was launched into a Sun-synchronous orbit on October 14, 2021. The scientific payload of the CHASE satellite is the Hα Imaging Spectrograph(HIS). The CHASE/HIS acquires, for the first time, seeing-free Hα spectroscopic observations with high spectral and temporal resolutions. It consists of two observational modes. The raster scanning mode provides full-Sun or region-of-interest spectra at Hα(6559.7-6565.9 ?) and Fe I(6567.8-6570.6 ?) wavebands. The continuum imaging mode obtains full-Sun photospheric images at around 6689 ?. In this paper, we present detailed calibration procedures for the CHASE/HIS science data, including the dark-field and flat-field correction, slit image curvature correction, wavelength and intensity calibration, and coordinate transformation. The higher-level data products can be directly used for scientific research. | Ye Qiu ShiHao Rao Chuan Li Cheng Fang MingDe Ding Zhen Li YiWei Ni WenBo Wang Jie Hong Qi Hao Yu Dai PengFei Chen XiaoSheng Wan Zhi Xu Wei You Yuan Yuan HongJiang Tao XianSheng Li YuKun He Qiang Liu | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，8： | 3 |

| 6 | A novel Hf-Si-O wire drawing phenomenon after ablation of SiC_(nws)/ HfC-SiC coating on C/C composites显示文摘A SiC_(nws)/HfC-SiC coating was fabricated by a two-step chemical vapor deposition.After introducing SiC nanowires,the fracture toughness of HfC-SiC coating increases by 228%.After ablation under oxyacetylene torch for 60s,a bone-like HfO_(2) reticular structure was formed in the central ablation area.Interestingly,a novel Hf-Si-O wire-drawing phenomenon was happened in the transition area of ablated SiC_(nws)/HfC-SiC coating,providing a new toughness mechanism under ablation environment.Moreover,HfO_(2) precipitated from Hf-Si-O glass wires to generate nanocrystalline grains during ablation,which explains the formation of bone-like HfO_(2) reticular structure observed from central ablation area. | Mingde Tong Qiangang Fu Shuotian Yao Tianyu Liu Tao Feng Dou Hu Lei Zhou | 2020 | Journal of Materiomics2020，6，2： | 0 |
| 7 | WEAK NONLINEAR WAVES IN NON-UNIFORM FLOW显示文摘In this paper, the wave velocity c is developed as an asymptotic series forweak nonlinear waves in non-uniform flow. Then Fredholm’s alternative theoremis applied and it is verified that the first-order approximation c1 equals zero,This generalizes the previous result. | TAO MINGDE, Fudan University,Shanghai, P.R.China | 1989 | Journal of Hydrodynamics1989，1，1： | 0 |
