| 1 | Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. | Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan | 2015 | Light(Science & Applications)2015，4，1： | 47 |
| 2 | Stitching algorithm for ion beam figuring of optical mirrors显示文摘A novel stitching machining method for ion beam figuring of optical mirrors is presented in this paper. Problems that should be dealt with in the stitching process such as shaping principle,algorithm for dwell time calculation,parameter identification and compensation for positioning errors are discussed. Based on Computer Controlled Optical Surfacing(CCOS)principle,the finite field nonlinear model is deduced from the stitching shaping mechanism;with the superposition property in the model,a modified Richardson-Lucy iterative algorithm is presented to deconvolute the dwell time for the stitching process;the effect of the positioning errors and the removal rate on the machining accuracy and shape is modeled and then the identification and compensation algorithm for these parameters is proposed based on this model.With these studies,shaping theory and algorithm are constructed,and then the stitching process for ion beam figuring comes into being.Figuring experiments are made on planar samples;the process convergence ratio is 10,which is similar to that in full aperture figuring.Theo- retical and experimental studies indicate that the stitching theory and algorithm in the ion beam figuring process presented in this paper are a novel method for fabrication of precision mirrors with lower cost. | ShengYi Li ChangJun Jiao XuHui Xie Lin Zhou | 2009 | Science China(Technological Sciences)2009，52，12： | 3 |

| 7 | 全基因组关联研究发现中国人群前列腺癌两个新易感位点9q31.2和19q13.4显示文摘0前言在全球范围内,前列腺癌的发病率和病死率存在着巨大差异。该病在西方发达国家发病率最高,在非裔美国人群病死率最高,而在亚洲人群中发病率及病死率均为全球最低,提示不同人种在前列腺癌的遗传方面存在异质性。在欧美和日本人群中,全基因组关联研究(GWAS)技术已经被用于检测前列腺癌的遗传易感性位点,但至今尚无关于GWAS检测中国人群前列腺癌易感位点的报道。 | Jianfeng Xu Zengnan Mo Dingwei Ye Meilin Wang Fang Liu Guangfu Jin Chuanliang Xu Xiang Wang Qiang Shao Zhiwen Chen Zhihua Tao Jun Qi Fangjian Zhou Zhong Wang Yaowen Fu Dalin He Qiang Wei Jianming Guo Denglong Wu Xin Gao Jianlin Yuan Gongxian Wang Yong Xu Guozeng Wang Haijun Yao Pei Dong Yang Jiao Mo Shen Jin Yang Jun Ou-Yang Haowen Jiang Yao Zhu Shancheng Ren Zhengdong Zhang Changjun Yin Xu Gao Bo Dai Zhibin Hu Yajun Yang Qijun Wu Hongyan Chen Peng Peng Ying Zheng Xiaodong Zheng Yongbing Xiang Jirong Long Jian Gong Rong Na Xiaoling Lin Hongjie Yu Sha Tao Junjie Feng Jishan Sun Wennuan Liu Ann Hsing Jianyu Rao Qiang Ding Fredirik Wiklund Henrik Gronberg Xiao-Ou Shu Wei Zheng Hongbing Shen Li Jin Rong Shi Daru Lu Xuejun Zhang Jielin Sun S Lilly Zheng Yinghao Sun | 2013 | 第二军医大学学报2013，34，4： | 0 |
| 8 | The Greenhouse Climate Records from Organic Carbon Isotope Excursions During the Toarcian (Early Jurassic) Sediments in the Shuanghu Area, Qianghai-Tibetan Plateau显示文摘Objective The organic-matter-rich oil shales outcropped at the Biluo Co area of the Qiangtang Basin in Tibet are of the Toarcian(Early Jurassic)based on the ammonite fauna(Yi et al.,2003).We first proposed its sedimentary age to be the Early Toarcian and correlated with the Posidonia shales and the early Toarcian Oceanic Anoxic Event(TOAE)(Chen et al.,2005).The carbon isotopes excursions and Buchi bivalves suggest that these oil shales at the Biluo Co section are represent of T-OAE in the Asian Tethyan regions. | YI Haisheng JI Changjun DA Xuejuan YI Fan XIA Guoqing LI Gaojie CHEN Lan JIAO Haijing WU Chihua | 2019 | Acta Geologica Sinica(English Edition)2019，93，3： | 0 |
