[目的/意义]基于社会网络媒体的学术交流与共享越来受到关注,因此Altmetric被提出并应用于论文的影响力评价,而国内对于Altmetric的研究尚处于理论阶段,且尚未有关于Altmetric应用于科研机构产出影响力评价的研究。[方法/过程]对Altmetric在科研机构产出影响力评价中的应用进行了理论和实践的研究,对Altmetric的功能作用、Altmetric工具以及与传统计量的对比进行了详细介绍,并以英国格拉斯哥大学的Altmetric Explore数据库为例对格拉斯哥大学的论文产出进行了分析,从信息源、期刊、学科方向、院系等不同角度深入分析了其在社会网络媒体中的影响力,并与传统被引情况进行对照分析。[结果/结论]分析表明,Altmetric作为一种新型的计量指标,与被引次数相比可以准确反映新发表论文的质量,是评价科研机构成果影响力的一种重要方法和补充。

A DSP BASED ELECTRICITY METER WITH REMOTE READING

1998 Fourth International conference Signal Processing

作者： J.Zhang w.Oghanna c.L.Bai Faculty of Engineering & Physical Systems central Queensland University Institute of Optical communication Research Liao cheng General University

＜正＞The paper introduces a DSP based electricity meter system with multi-user and automatic meter reading *** consists of a Pc based master meter in the control station and a reasonable number of slave meters in the local residential *** power line carrier（PLc） technique is implemented so that the bi-directional communication can be conducted between master and slave *** slave meter was designed to replace fifteen or more convectional meters,which can significantly reduce the construction material and installation space for electricity *** results show that the accuracy of remote meter reading between 2-4am each morning is quite satisfactory.

聚环氧乙烯醚-聚环氧丙烯醚-聚环氧乙烯醚(EO20PO70EO20)三嵌段高分子为模板剂制备了SBA-15分子筛.用3-氨丙基-三乙氧基硅烷对SBA-15进行改性,改性后SBA-15表面上的氨基再与(+)O-,O′-二苯甲酰基-L-酒石酸酐(DBTA)进行酰化反应,以酰胺键将该手性羧酸连接在SBA-15表面上.XRD和氮气吸附结果表明,材料经过处理后仍然保持良好的孔性质;13c和29S i魔角旋转核磁共振(MAS NMR)谱图表明,SBA-15与氨丙基化合物的作用是共价成键,表面修饰度达25%;从傅里叶变换红外(FTIR)光谱可见,有部分修饰氨基与DBTA成功地进行了酰化反应,以一个羧基裸露的形式将该二元羧酸化合物连接在表面上;从孔径分布图可知,胺丙基修饰之后孔减小了1.5 nm,与DBTA修饰后孔尺寸又减少0.5 nm,说明胺丙基化合物是头对头垂直连接在S i表面上,而酒石酸分子是采取平行方式侧卧在氨基表面.
