| 1 | Variation of head and facial morphological characteristics with increased age of Han in Southern China显示文摘We investigated 13940 (6735 male, 7250 female) adult head and facial physical attributes from 19 different Han ethnic groups in 10 southern-China provinces, and calculated 12 head and facial indexes. Indexes were used to analyze the variation of head and facial morphological characteristics with increased age. Results showed that as age increases: (1) Head breadth, minimum frontal breadth, face breadth, interocular breadth, external biocular breadth, lip height, lip thickness, head circumference, auricular height, length-breadth head index, length-height head index, and lip-index values decline significantly in a linear fashion. (2) Nose breadth, mouth breadth, morphological facial height, upper-lip height, physiognomic ear length, physiognomic ear breadth, visor skin-fold, and vertical head-facial index values significantly increase in a linear fashion. | LI YongLan ZHENG LianBin YU KeLi LU ShunHua ZHANG XingHua LI YuLing WANG Yang XUE Hong DENG Wei | 2013 | Chinese Science Bulletin2013，58，4： | 20 |

| 3 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016，1，1： | 2 |
| 4 | Bismuth doped lead-free two-dimensional tin based halide perovskite single crystals显示文摘Heterovalent-metal doping is an efficient tool to tune the optoelectronic properties of the famous halide perovskites.Previous studies have focused on the heterovalent-doping in three-dimensional(3D) halide perovskites.However, there is a lack of such doping in two-dimensional perovskites which possess unique optoelectronic properties and improved chemical stability as compared to 3D analogues.Here, we present successful doping of Bismuth into the lattice of lead-free, two-dimensional perovskite PEA2SnBr4 single crystals.Structural characterizations demonstrate that the doped crystals possess identical crystal structure and layered morphology with the pristine one.Intriguingly, we find the PL peak and spectral shape can be tailored by tuning the concentration of Bi dopants.Femtosecond transient absorption spectroscopy is performed to understand the underlying mechanism related to tunable PL behaviors, and a clear picture of the Bismuth-doping impact is provided. | Ruiling Zhang Xin Mao Pengfei Cheng Yang Yang Songqiu Yang Tuerdi Wumaier Weiqiao Deng Keli Han | 2019 | Journal of Energy Chemistry2019，28，9： | 2 |

| 6 | High performance streaked X-ray spectrometer for research of laser-produced plasmas显示文摘In order to mitigate the effect of the strong electromagnetic pulse, which produces laser-plasma interactions, we designed a new streaked X-ray spectrometer (SXS) enclosed within a well-sealed, electromag- netic interference-free cavity. The SXS can cover a wide selection of spectral windows using interchangeable Bragg crystals and by appropriate adjustment of the Bragg angle. The SXS has been used to observe time-re- solved X-ray spectrum in the 2.5 keV to 3.5 keV photon-energy range, resulting in a demonstrated spectral res- olution of about 13 at 2960 eV with a time resolution of 10 ps. The observed time and spectral resolutions dem- onstrate the applicability of the SXS for studies of laser-produced plasmas. | Guo Luting Wei Minxi Hu Xin Deng Keli Chen Tao Deng Bo Zhang Lu Zhao Yang Li Jin Xiao Shaoqiu Liu Shenye | 2016 | 强激光与粒子束2016，28，2： | 0 |
| 7 | First experimental comparisons of laser-plasma interactions between spherical and cylindrical hohlraums at SGⅢ laser facility显示文摘We present our recent laser-plasmas instability(LPI)comparison experiment at the SGIII laser facility between the spherical and cylindrical hohlraums.Three kinds of filling are considered:vacuum,gas-filling with or without a capsule inside.A spherical hohlraum of 3.6 mm in diameter,and a cylindrical hohlraum of 2.4 mm?4.3 mm are used.The capsule diameter is 0.96 mm.A flat-top laser pulse with 3 ns duration and up to 92.73 kJ energy is used.The experiment has shown that the LPI level in the spherical hohlraum is close to that of the outer beam in the cylindrical hohlraum,while much lower than that of the inner beam.The experiment is further simulated by using our 2-dimensional radiation hydrodynamic code LARED-Integration,and the laser back-scattering fraction and the stimulated Raman scatter(SRS)spectrum are post-processed by the high efficiency code of laser interaction with plasmas HLIP.According to the simulation,the plasma waves are strongly damped and the SRS is mainly developed at the plasma conditions of electron density from 0.08 n_(c) to 0.1 n_(c) and electron temperature from 1.5 keV to 2.0 keV inside the hohlraums.However,obvious differences between the simulation and experiment are found,such as that the SRS back-scattering is underestimated,and the numerical SRS spectrum peaks at a larger wavelength and at a later time than the data.These dif-ferences indicate that the development of a 3D radiation hydrodynamic code,with more accurate physics models,is mandatory for spherical hohlraum study. | Yaohua Chen Zhichao Li Xufei Xie Chunyang Zheng Chuanlei Zhai Liang Hao Dong Yang Wenyi Huo Guoli Ren Jie Liu Xiaoshi Peng Tao Xu Yulong Li Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Yonggang Liu Huiyue Wei Xiangming Liu Weiyi Cha Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Haijun Zhang Baibin Jiang Wei Zhang Kai Du Xuewei Deng Yongkun Ding Xiaofeng Wei Wanguo Zheng Xiaodong Chen Xiantu He Ke Lan | 2017 | Matter and Radiation at Extremes2017，2，2： | 0 |
| 8 | Single crystal-single crystal bonding of langasite exhibited high strength of 23.28 MPa显示文摘Langasite(LGS,La_(3)Ga_(5)SiO_(14))is a promising material in high-temperature piezoelectric devices due to its excellent thermal stability,piezoelectricity,and electrical property.A major challenge in the development of LGS-based devices is to form high-strength bonding of the brittle LGS.Here,we report that the single crystal-single crystal(dual-SC)bonding of LGS is realized through thermal activation under a low com-pression of 50 kPa for the first time.A record bonding strength of 23.28 MPa is achieved within the dual-SC bonded LGS/LGS structure(with a high bonding ratio exceeding 93%),which is 5 times higher than that of the recent reported LGS/LGS bonding structure(in which a relatively fragile amorphous interface layer is formed between the two LGS samples).The smooth and void-free dual-SC bonding interface of LGS is verified via the cross-sectional transmission electron microscopy(TEM)observations. | Guangyao Pei Binghe Ma Tao Ye Zhonggang Zhang Keli Zhao Jinjun Deng Seeram Ramakrishna Jian Luo | 2023 | Journal of Materials Science & Technology2023，，29： | 0 |
| 9 | First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole显示文摘The octahedral spherical hohlraums have natural superiority in maintaining high radiation symmetry during the entire capsule implosion process in indirect drive inertial confinement fusion.While,in contrast to the cylindrical hohlraums,the narrow space between the laser beams and the spherical hohlraum wall is usually commented.In this Letter,we address this crucial issue and report our experimental work conducted on the SGIII-prototype laser facility which unambiguously demonstrates that a simple design of cylindrical laser entrance hole(LEH)can dramatically improve the laser propagation inside the spherical hohlraums.In addition,the laser beam deflection in the hohlraum is observed for the first time in the experiments.Our 2-dimensional simulation results also verify qualitatively the advantages of the spherical hohlraums with cylindrical LEHs.Our results imply the prospect of adopting the cylindrical LEHs in future spherical ignition hohlraum design. | Wenyi Huo Zhichao Li Dong Yang Ke Lan Jie Liu Guoli Ren Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Xuefei Xie Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Guanghui Yuan Haijun Zhang Baibin Jiang Lizhen Huang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Yongkun Ding Xiantu He Weiyan Zhang | 2016 | Matter and Radiation at Extremes2016，1，1： | 0 |
