印度家禽进口禁令争端是首次发展中国家因"农业疫病威胁"限制农产品进口而受到WTO《SPS协定》规则的挑战。美国起诉印度因禽流感威胁而实施家禽进口禁令,违反了《SPS协定》中"国际协调""适应地区条件""风险评估"和"充足科学证据"等多项规则。本文剖析了美国和印度家禽产品贸易争端发起的现实背景;双方就上述条款的不同主张,以及争端裁决中对《SPS协定》规则的澄清,能够透视出美国家禽产品出口策略,以及全球性农业疫病频发下,农产品进口限制措施需遵循的国际规则。本研究对不断开放的中国农产品市场制定符合《SPS协定》规则的进口限制措施具有重要意义。

Double carbohelicenes have attracted considerable attention due to their aesthetic structures, distinct π-conjugation extension, inherent chirality, and intriguing optical and electronic properties. Herein, the concise de novo synthesis of a new double[5]carbohelicene 1 together with its chiroptical properties, isomerization process and lasing application is presented. 1 was synthesized by a simple protocol involving the formation of a 6,6′-bipentacene as the key intermediate. It is worth noting that1 existed as two diastereomers 1-PP/MM and 1-PM, which were successfully isolated and unambiguously confirmed by Xray crystallography. The optical resolution of the racemic 1-PP/MM was successfully achieved by chiral-phase highperformance liquid chromatography（HPLC）, and 1-PP and 1-MM were characterized by circular dichroism. Interestingly, it was found that 1-PP/MM could be completely isomerized to 1-PM upon heating, and the detailed thermodynamics and kinetics of the isomerization process were systematically investigated. 1-PM exhibited deep-red luminescence with emission maximum at 723 nm and fluorescence quantum yield as high as 32.95%. Consequently, we can showcase the lasing application of 1-PM by doping with epoxy resin to assemble a bottle microlaser spontaneously, which the lasing wavelength is 796.6 nm at a threshold of 0.8 m J cm-2. We believe that our studies, including the facile synthesis methodology, detailed isomerization studies, and lasing application, will shed some light on the design and synthesis of novel carbohelical systems with more functions.

[目的]探究二氯吡啶酸飘移对邻作作物辣椒的药害影响以及复硝酚钠对其的缓解效果。[方法]以青云2号辣椒为试验试材,采用喷洒二氯吡啶酸稀释液的方法模拟药液飘移,喷施复硝酚钠后分别观察叶、茎组织变化并测定比较辣椒苗期叶片的抗氧化酶活性和丙二醛、叶绿素、类胡萝卜素、谷胱甘肽含量。[结果]在施药后7 d内,随着二氯吡啶酸质量浓度升高,辣椒苗的药害症状加重,其叶片的MDA含量逐渐升高,CAT、POD、SOD活性和叶绿素、类胡萝卜素含量呈先升高后降低的趋势,GSH含量在施药后3~7 d内随质量浓度升高而降低。其中二氯吡啶酸质量浓度为0.016 g/L时,辣椒新叶畸形黄化,茎结构开始出现损伤,质量浓度为0.800 g/L时,施药后7 d,叶片畸形严重并出现部分干枯,茎结构的完整性被破坏,各项生理指标均显著低于对照组;喷施复硝酚钠缓解后,二氯吡啶酸质量浓度为0.016、0.040 g/L时,辣椒药害现象缓解明显,MDA含量降低,CAT、POD、SOD显著升高,叶绿素、类胡萝卜素、GSH含量升高;二氯吡啶酸浓度为0.800 g/L时,喷施复硝酚钠无明显缓解效果。[结论]二氯吡啶酸飘移会对邻作作物辣椒产生不同程度的药害,浓度越高,药害症状越重,喷施复硝酚钠能在一定程度上缓解二氯吡啶酸对辣椒的药害症状。

针对机场噪声监测无线传感网络中的最小连通覆盖集问题,设计了一种基于目标区域Voronoi划分的集中式近似算法,用于分析完全覆盖目标区域所需的最低要求的节点集;为了更好地调整噪声监测节点的感知半径Rs与通信半径Rc的比值关系,在通信半径小于两倍感知半径时,提出了一种基于最小生成树的连通算法用以确保CVT算法构造的覆盖集连通所需的辅助节点。理论分析与仿真实验表明,与现有常用的集中式贪婪算法和DVC算法相比,CVT(+MST)算法的性能在时间复杂性和连通覆盖集大小等两方面都较优。
