| 1 | 不同雨强、坡度对秸秆覆盖保持水土效果的影响显示文摘利用室内人工模拟降雨试验,研究了4种设计雨强(33,54,94,125mm/h)、3种设计坡度(5°,10°,25°)在覆盖条件下对紫色土坡面初始产流时间、覆盖保水率和保沙率的影响。结果表明:覆盖条件下初始产流时间相比裸地均有一定的滞后效果,且其初始产流的滞后时间随坡度、雨强的增加而减少。当坡度增大至25°,雨强在94mm/h以上时,其滞后时间逐渐趋于稳定,在1.61~2.84min范围内波动。雨强是影响秸秆覆盖保持水土作用的重要因子,与覆盖保水率、保沙率均在0.01水平上呈显著负相关,且在不同坡度条件下均可以用抛物线进行很好的描述。不同坡度条件下,覆盖的保水率随雨强的增加逐渐下降至14.5%,而其保沙率则只下降至92.25%,相比覆盖的保水作用,其保沙作用更加明显。覆盖条件下,坡度对坡面产流及产沙的贡献率均大于50%,坡度对秸秆覆盖保持水土的作用影响很大。坡度对坡面侵蚀的贡献率在裸地和覆盖条件下均随雨强的增加而呈现减小的趋势,且在相同雨强下,坡度的贡献率在覆盖条件下均大于裸地,在大雨强下(94mm/h和125mm/h)差异明显。 | 车明轩 宫渊波 Muhammad Naeem Khan 陈兆利 曾倩 兰依依 | 2016 | 水土保持学报2016，30，2： | 17 |
| 2 | 欧洲地熊蜂对我国本土熊蜂的生殖干扰评估显示文摘【目的】外来物种与本土亲缘关系较近的物种可能会发生交尾竞争,干扰本土物种的正常繁衍。欧洲地熊蜂Bombus terrestris是全球范围内商业化应用最广的传粉蜂种,但在许多国家造成了生物入侵。本研究旨在明确欧洲地熊蜂对我国本土熊蜂产生生殖干扰的可能性。【方法】采用四级杆飞行时间-气质联用系统(gas chromatography-quadrupole time of flight mass spectrometry,GC-QTOF/MS)测定了欧洲地熊蜂和我国本土9种熊蜂的雄蜂头部分泌物的成分,并进行聚类分析;在人工控制环境下比较了欧洲地熊蜂对我国重要熊蜂种类的交尾影响。【结果】雄蜂头部分泌物气质色谱图在同一熊蜂种内基本一致,而在不同熊蜂种之间差异明显;我国红光熊蜂B.ignitus、兰州熊蜂B.lantschouensis与欧洲地熊蜂的雄蜂头部分泌物成分相似性分别为58.49%与49.23%;在人工控制环境下欧洲地熊蜂雄蜂可以与兰州熊蜂蜂王杂交,并能够显著降低兰州熊蜂的交尾成功率(P<0.01)。【结论】欧洲地熊蜂与我国一些熊蜂种的雄蜂头部分泌物成分相似性较高,能够干扰其正常交尾,具有较高的生殖干扰风险。为了保护我国本土熊蜂资源与生态系统平衡避免造成生物入侵,我们应该谨慎使用外来熊蜂物种。 | 袁晓龙 Muhammad NAEEM 张红 梁铖 黄家兴 安建东 | 2018 | 昆虫学报2018，61，3： | 9 |

| 4 | Three Tier Fog Networks: Enabling IoT/5G for Latency Sensitive Applications显示文摘Following the progression in Internet of Things(IoT) and 5G communication networks, the traditional cloud computing model have shifted to fog computing. Fog computing provides mobile computing, network control and storage to the network edges to assist latency critical and computation-intensive applications. Moreover, security features are improved in fog paradigm by processing critical data on edge devices instead of data centres outside the control plane of users. However, fog network deployment imposes many challenges including resource allocation, privacy of users, non-availability of programming model and testing software and support for the heterogenous networks. This article highlights these challenges and their potential solutions in detail. This article also discusses threetier fog network architecture, its standardization and benefits in detail. The proposed resource allocation mechanism for three tier fog networks based on swap matching is described. Results show that by practicing the proposed resource allocation mechanism, maximum throughput with reduced latency is achieved. | Romana Shahzadi Ambreen Niaz Mudassar Ali Muhammad Naeem Joel J.P.C.Rodrigues Farhan Qamar Syed Muhammad Anwar | 2019 | China Communications2019，16，3： | 6 |

| 6 | Silver modified Cu/SiO2 catalyst for the hydrogenation of methyl acetate to ethanol显示文摘A series of silver modified Cu/SiO2 catalysts were synthesized with ammonia-evaporation method and applied in vapor-phase hydrogenation of methyl acetate to ethanol.The influence of additive‘Ag’on the structural evolution of catalyst was systematically studied by several characterization techniques,such as N2 adsorption–desorption,N2O titration,PXRD,FTIR,in-situ FTIR,H2-TPR,H2-TPD,XPS and TEM.Results showed that incorporation of a small amount of Ag could enhance the structural stability,and the strong interaction between Cu and Ag species was conducive to increase the dispersion of copper species and create a suitable Cu+/(Cu0+Cu+)ratio,which was proposed to be responsible for the improved catalytic activity.The maximum conversion of MA(94.1%)and selectivity of ethanol(91.3%)over optimized Cu-0.5 Ag/SiO2 and 120 h on stream without deactivation under optimal conditions demonstrates its excellent stability. | Zhiheng Ren Muhammad Naeem Younis Hui Zhao Chunshan Li Xiangui Yang Erqiang Wang Gongying Wang | 2020 | Chinese Journal of Chemical Engineering2020，28，6： | 4 |
