| 2 | Production and emission of phosphine gas from wetland ecosystems显示文摘Phosphine is a part of an atmospheric link of phosphorus cycle on earth, which could be an important pathway for phosphorus transport in environment.Wetland ecosystems are important locations for global biogeochemical phosphorus cycle.In this study, production and emission fluxes of free phosphine from four wetlands types in southern China were observed in different seasons.The results showed that the concentration of phosphine liberated from wetlands was at pg/m3-ng/m3 level.The emission concentrations of different wetlands followed the sequence:paddy field(51.83 ± 3.06) ng/m3 marsh(46.54 ± 20.55) ng/m3 > lake(37.05 ± 22.74) ng/m3 coastal wetland(1.71 ± 0.73) ng/m3, the positive phosphine emission flux occurred in rice paddy field(6.67 ± 5.18) ng/(m2·hr) and marsh(6.23 ± 26.9) ng/(m2·hr), while a negative phosphine flux of(-13.11 ± 35.04) ng/(m2·hr) was observed on the water-air interface of Lake Taihu, suggesting that paddy field and marsh may be important sources for phosphine gas in atmosphere, while lake may be a sink of atmospheric phosphine gas during the sampling period.Atmospheric phosphine levels and emission flux from Yancheng marsh and rice paddy field varied in different seasons and vegetational zones.Both diffusion resistance in aqueous phase and temperature were dominating factors for the production and transportation of phosphine to atmosphere. | Chao Han Xueyuan Gu Jinju Geng Yuning Hong Rui Zhang Xiaorong Wang Shixiang Gao | 2010 | Journal of Environmental Sciences2010，22，9： | 5 |
| 3 | Phytotoxicity of four herbicides on Ceratophyllum demersum,Vallisneria natans and Elodea nuttallii显示文摘The physiological effects of 4 herbicides(butachlor,quinclorac,bensulfuron-methyl and atrazine) on 3 submerged macrophytes(Ceratophyllum demersum,Vallisneria natans and Elodea nuttallii) were tested in laboratory.The variables of the relative growth rate and the photosynthetic pigment content showed that all of the tested herbicides affected the growth of the plants obviously,even at the lowest concentration(0.0001 mg/L).Except for the C.demersum treated with quinclorac at 0.005 and 0.01 mg/L,the relative growth rates of the plants were inhibited significantly(p < 0.01).Statistical analysis of chlorophyll a(Chl-a) contents was carried out with both the t-test and one-way ANOVA to determine the difference between the treatment and control.The results showed that Chl-a contents of the plants in all treatment groups were affected by herbicides significantly,except for the C.demersum treated with bensulfuron-methyl at 0.0005 mg/L.The decrease in Chla content was positively correlated to the dosage of the herbicides in most treatment groups.It was suggested that herbicides in water bodies might potentially affect the growth of aquatic macrophytes.Since the Chl-a content of submerged macrophytes responded to the stress of herbicides sensitively and directly,it could be used as a biomaker in environmental monitoring or in the ecological risk assessment of herbicide contamination. | PAN Huiyun,LI Xiaolu,XU Xiaohua,GAO Shixiang State Key Laboratory of Pollution Control and Resource Reuse,School of the Environment,Nanjing University,Nanjing 210093,China. | 2009 | Journal of Environmental Sciences2009，21，3： | 4 |
| 4 | Progress in the beam commissioning of separated function RFQ accelerator显示文摘Separated Function RFQ (SFRFQ) was proposed as a post accelerator of RFQ to accelerate heavy ions at low frequency. It introduces gap accelerating in the quadrupole electrodes, and therefore it has higher accelerating efficiency than the conventional RFQ accelerator. The first SFRFQ prototype cavity has been specially designed and constructed as a post accelerator to accelerate O+ beam from 1.03 MeV to 1.64 MeV. Based on accomplishment of low power measurement and high power test, the beam commissioning was carried out to verify its feasibility. The measured energy gain per cell of SFRFQ is 45 keV, which is about 60% higher than that of Peking University Integral Split Ring (ISR) RFQ. | MingLei Kang (1) YuanRong Lu (1) Zhi Wang (1) Kun Zhu (1) XueQing Yan (1) ZhiYu Guo (1) ShuLi Gao (1) ShiXiang Peng (1) Ao Liu (2) JiaXun Fang (1) JiaEr Chen (1) | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S2： | 2 |

| 14 | High-gain amplification for femtosecond optical vortex with mode-control regenerative cavity显示文摘Ultra-intense femtosecond vortex pulses can provide an opportunity to investigate the new phenomena with orbital angular momentum(OAM)involved in extreme cases.This paper reports a high gain optical vortex amplifier for intense femtosecond vortex pulses generation.Traditional regeneration amplifiers can offer high gain for Gaussian mode pulses but cannot amplify optical vortex pulses while maintaining the phase singularity because of mode competition.Here,we present a regeneration amplifier with a ring-shaped pump.By controlling the radius of the pump,the system can realize the motivation of the Laguerre–Gaussian[LG0,1(−1)]mode and the suppression of the Gaussian mode.Without seeds,the amplifier has a donut-shaped output containing two opposite OAM states simultaneously,as our prediction by simulation.If seeded by a pulse of a topologic charge of 1 or−1,the system will output an amplified LG0,1(−1)mode pulse with the same topologic charge as the seed.To our knowledge,this amplifier can offer the highest gain as 1.45×106 for optical vortex amplification.Finally,we obtain a 1.8 mJ,51 fs compressed optical vortex seeded from a 2 nJ optical vortex. | SHUIQIN ZHENG ZHENKUAN CHEN QINGGANG LIN YI CAI XIAOWEI LU YANXIA GAO SHIXIANG XU DIANYUAN FAN | 2020 | Photonics Research2020，8，8： | 0 |
