无线电监测数据可视化平台的设计与实现

无线电监测的手段相对复杂,而且成本很高,对于2007年至今积累的具有很高价值且来之不易的无线电监测数据,如何合理地使用这些数据,成为了无线电管理研究的重要工作之一。目前随着技术的快速发展,利用技术手段对监测数据进行数据管理和可视化的分析,能够提高无线电监测数据的使用率。本文深入地研究了无线电监测数据可视化的方法,并研发了基于无线电监测数据的可视化平台。该可视化过程将海量监测数据进行科学存储,对表格化数据利用ETL进行抽取汇总,对无线电监测数据进行统计分析,再与ArcGIS进行整合,对无线电监测数据进行多元化可视化的展示。

莱布尼茨与俄国近代科学体系的建立——以科学知识生产、存储和传播为中心的考察

在17世纪科学院运动的风潮下,莱布尼茨对于在世界范围内建立一个庞大的科学院网络有着明确的规划,其中尚处于科学空白阶段的俄国是这个网络中至关重要的一环。莱布尼茨对于俄国近代科学知识体系的建立有着重要的影响,与彼得一世及其宫廷的书信来往证实了莱布尼茨的建议直接推动了俄国科学院的建立。莱布尼茨构想的俄国科学院体系庞大,涵盖附属大学、珍品博物馆、图书馆等一系列部门。他以科学知识的生产和获取、存储和系统化、传播和内化为线索,具体从科学院组织的科学探险活动、科学院体制下的博物馆项目、科学院的教育与出版工作中构建出一整套与其心目中的俄国现状相适应的科学知识发展体系。彼得一世从俄国特定的社会文化环境出发创建科学系统,措施兼具莱布尼茨的科学构想及本土化特点,对俄国科学的近代化、社会思想意识向理性转变产生了深远的影响。

The development history and enlightenment of the scientific data services of American university libraries

In the era of the big data. the national strategies and the rapid development of computers and storage technologies bring opportunities and challenges to the library＇s data services. Based on the investigation literature of the scientific data services in the university libraries in the United States, the development process of the scientific data is analyzed from three aspects of the service types, the service mode and the service contents. The author of this paper also proposes opportunities and challenges from 5 aspects of the policy support. strengthening the publicity, the self learning, the self positioning and relying on the embedded subject librarians, to promote the development of the library scientific data services.

中医院药房中草药的科学储藏与保管分析

目的:本文对中医院药房中草药科学储藏和保管方法进行简要论述,以供临床参考。方法:选取我院药房自2014年3月到2017年3月采购质量相同的40份中草药进行分组研究,分成观察组和对照组,每组20份,观察组采用科学储藏、保管办法进行管理,对照组采用常规储藏、保管办法进行管理。结果:分别对40份中草药质量进行检测,根据中草药管理质量检测结果可以看出,观察组药材的变质率明显低于对照组药材,对比结果P<0.05且具有统计学意义。结论:通过科学储藏与保管可以提升中草药质量,使治疗效果得到显著提升,也使医院药房的声誉有所提升,因此,中草药科学储藏和保管值得在中医院药房中推广使用。

Biomass-derived carbon materials with structural diversities and their applications in energy storage

Currently, carbon materials, such as graphene,carbon nanotubes, activated carbon, porous carbon, have been successfully applied in energy storage area by taking advantage of their structural and functional diversity. However, the development of advanced science and technology has spurred demands for green and sustainable energy storage materials.Biomass-derived carbon, as a type of electrode materials, has attracted much attention because of its structural diversities,adjustable physical/chemical properties, environmental friendliness and considerable economic value. Because the nature contributes the biomass with bizarre micro structures,the biomass-derived carbon materials also show naturally structural diversities, such as OD spherical, 1D fibrous, 2D lamellar and 3D spatial structures. In this review, the structure design of biomass-derived carbon materials for energy storage is presented. The effects of structural diversity, porosity and surface heteroatom doping of biomass-derived carbon materials in supercapacitors, lithium-ion batteries and sodium-ion batteries are discussed in detail. In addition, the new trends and challenges in biomass-derived carbon materials have also been proposed for further rational design of biomass-derived carbon materials for energy storage.
