| 1 | Influence of Range Gate Width on Detection Probability and Ranging Accuracy of Single Photon Laser Altimetry Satellite显示文摘The influence of the single photon laser altimeter range-gate width on the detection probability and ranging accuracy is discussed and analyzed,according to the LiDAR equation,single photon detection equation and the Monte Carlo method to simulate the experiment.The simulated results show that the probability of detection is not affected by the range gate,while the probability of false alarm is relative to the gate width.When the gate width is 100 ns,the ranging accuracy can accord with the requirements of satellite laser altimeter.But when the range gate width exceeds 400 ns,ranging accuracy will decline sharply.The noise ratio will be more as long as the range gate to get larger,so the refined filtering algorithm during the data processing is important to extract the useful photons effectively.In order to ensure repeated observation of the same point for 25 times,we deduce the quantitative relation between the footprint size,footprint,and frequency repetition according to the parameters of ICESat-2.The related conclusions can provide some references for the design and the development of the domestic single photon laser altimetry satellite. | Guoyuan LI Fanghong YE Xinming TANG Dongping XIE Jiapeng HUANG Genhua HUANG | 2020 | Journal of Geodesy and Geoinformation Science2020，3，2： | 4 |
| 2 | Using irrigation intervals to optimize water-use efficiency and maize yield in Xinjiang,northwest China显示文摘Worldwide, scarce water resources and substantial food demands require efficient water use and high yield.This study investigated whether irrigation frequency can be used to adjust soil moisture to increase grain yield and water use efficiency(WUE) of high-yield maize under conditions of mulching and drip irrigation.A field experiment was conducted using three irrigation intervals in 2016: 6, 9, and 12 days(labeled D6, D9, and D12) and five irrigation intervals in 2017: 3, 6, 9, 12, and 15 days(D3, D6, D9, D12, and D15).In Xinjiang, an optimal irrigation quota is 540 mm for high-yield maize.The D3, D6, D9, D12, and D15 irrigation intervals gave grain yields of 19.7, 19.1–21.0, 18.8–20.0, 18.2–19.2, and 17.2 Mg ha^-1 and a WUE of 2.48, 2.53–2.80, 2.47–2.63, 2.34–2.45, and 2.08 kg m-3, respectively.Treatment D6 led to the highest soil water storage, but evapotranspiration and soil-water evaporation were lower than other treatments.These results show that irrigation interval D6 can help maintain a favorable soil-moisture environment in the upper-60-cm soil layer, reduce soilwater evaporation and evapotranspiration, and produce the highest yield and WUE.In this arid region and in other regions with similar soil and climate conditions, a similar irrigation interval would thus be beneficial for adjusting soil moisture to increase maize yield and WUE under conditions of mulching and drip irrigation. | Guoqiang Zhang Dongping Shen Bo Ming Ruizhi Xie Xiuliang Jin Chaowei Liu Peng Hou Jun Xue Jianglu Chen Wanxu Zhang Wanmao Liu Keru Wang Shaokun Li | 2019 | The Crop Journal2019，7，3： | 4 |

| 7 | Manganese-Catalyzed Hydrocar bofun ctionalization of Internal Alkenes显示文摘Summary of main observation and conclusion A highly regio-and chemo-selective dimeric Mn⑴-catalyzed hydroarylation and hydroalkenylation of unbiased internal alkenes with commercially abundant organoboron compounds is reported.A wide range of densely functionalized aliphatic alkenyl amides can successfully undergo site-exclusive hydrocarbofunctionalization in air atmosphere without any exogenous directing auxiliary,affording an enhanced lead library of structurally diverse y-functionalized carboxylic acid derivatives in moderate to good yields.The precise chemoselectivity of the reaction among multiple alkene units even in the presence of reactive terminal alkenes highlights the unique catalytic features of manganese catalyst,and the excellent functional group compatibility of primary amides further complements other transition metals. | Dongping Wang Yijie He Haotian Dai Congcong Huang Xiang-Ai Yuan Jin Xie | 2020 | Chinese Journal of Chemistry2020，38，12： | 1 |
