摘要：To address the issues of reduced graphene oxide(RGO) dispersion in copper(Cu) matrix and interface bonding between RGO and Cu, an electrostatic adsorption method with interface transition phase design was employed to prepare the RGO/Cu based composites. Cu-Ti alloy powder was employed to improve the combination by forming carbides at the RGO-Cu interface. It was noted that the mechanical property of 0.3 wt.%RGO/Cu-Ti composite was increased by 60% compared with that of the matrix. Strengthening mechanism analysis suggested that the enhancement of the mechanical property was ascribed to the load transfer and second phase strengthening which were from the improved dispersion of RGO and the in-situ formed titanium carbide phase.

摘要：本文针对多艘拖轮对海上大型船舶进行带缆伴航的问题,提出一种基于分层模型预测控制的带缆自主伴航控制策略。在顶层考虑带缆伴航安全性约束,设计基于多约束MPC的轨迹规划器以规划安全的拖轮伴航轨迹,并提出前置预优化机制解决多安全性约束下的初始解猜测问题。在底层基于双全回转推进器特性设计轨迹跟踪控制器,控制拖轮跟踪顶层规划的安全轨迹,实现多拖轮带缆自主伴航控制。仿真试验结果表明,所提控制策略可以实现安全的多拖轮带缆自主伴航控制,可为拖轮自主伴航的应用提供理论参考。

摘要：A new substrate,aligned Ag nanowires decorated with silver nanoparticle composite structure(AgNWs@AgNPs),was fabricated to investigate metalenhanced fluorescence(MEF) and its *** new composite structure was fabricated via a three-phase interface assembly method followed by SnCl2 sensitization and AgNO3 reduction *** size and distribution of the nanoparticles on silver nanowires increased with the sensitization and reduction *** formation of AgNPs on the surfaces of AgNWs was confirmed by multiple characterization methods including scanning electron microscopy(SEM),transmission electron microscope(TEM),atomic force microscopy(AFM) and X-ray diffraction(XRD).The results show that the fluorescence intensity of the poly(3-hexylthiophene)(P3HT) on the composite structure was greatly enhanced compared with that on bare glass substrate,and the intensity increased with the increase in particle sizes and *** mechanism was basedo n the increase in excitation rate and the radiation decay *** new type of substrate could serve as a good and efficient MEF substrate for high-performance fluorescence-based devices.

摘要：Diamidine （A） was identified in our in vitro bio-assay as a possible inhibitor of ketol-acid reductoisomerase （KARI） from the ACD database search based on the known three-dimensional crystal structure of KARI. An investigation on interaction of A on KARI active sites, led to the design and synthesis of 15 novel monoamidines. Some of those showed better biological activity than A on rice KARI （in vitro） and in greenhouse herbicidal tests （in vivo）. The structure-biological activity relationship was investigated, which provides valuable information to further study of potential KARI inhibitors.

摘要：以徐紫薯8号为原料,研究物料水分含量、套筒温度、螺杆转速、喂料转速对紫甘薯膨化圈径向膨化率及硬度的影响。在单因素试验基础上,结合Box-Behnken试验设计,优化双螺杆挤压膨化工艺,进一步对膨化产品的水合特性、糊化特性及质构特性进行分析。结果表明:最佳挤压膨化工艺参数为物料水分含量12%、套筒温度149℃、螺杆转速28 Hz、喂料转速10 Hz,在此条件下产品膨化圈的径向膨化率为3.52,硬度为63.85 N,与理论预测值接近。全粉经挤压膨化后,徐紫薯8号膨化圈的水合特性明显提高,热糊稳定性和抗老化性得到改善,口感酥脆,更易剪切。

摘要：随着创意经济的崛起,建设创意型城市成了城市发展的新趋势。许多国际大都市都将它提上了战略发展的议事日程。创意型城市的核心要素包括技术、人才和包容三个方面。其中,吸引和培育创意阶层是建设创意型城市的关键。创意阶层的城市需求主要集中于三个方面,即有各种创意产业发展的机会、有各种参与的便利设施和有各种包容多样性的体制条件,这就要求城市通过具体的制度安排给创意阶层提供技术环境、人才环境和宽容环境,以吸引创意人才。

摘要：为有效鉴定熊科(Ursidae)物种,根据熊科动物线粒体细胞色素c氧化酶2(cytochrome c oxidase subunit 2,COX2)基因设计扩增片段为790 bp的通用引物,对9份熊科动物组织样本、4份熊科动物合成质粒和16份对照样本进行聚合酶链式反应(Polymerase Chain Reaction,PCR)扩增、电泳和测序,计算物种遗传距离,并采用邻接法构建进化树。结果显示:16份对照样本均未见扩增条带;9份熊科动物组织DNA和4份熊科动物合成质粒的检测结果符合预期,且与美国国家生物技术信息中心(National Center for Biotechnology Information,NCBI)参考序列的一致性均>96%;8种熊科动物的最大种内遗传距离为0.014%,最小种间遗传距离为0.022%,存在显著条形码差距。结果表明,本研究所建立的COX2基因DNA条形码方法能够准确鉴定熊科物种,可为海关等执法部门打击违法犯罪行为、履行《濒危野生动植物种国际贸易公约》提供技术支撑。
