我国9种情报学核心期刊载文被引分析 总被引:14,自引:0,他引:14
为了从期刊文献被引用角度,了解我国情报学研究成果交流、渗透和利用情况,客观评价情报学核心期刊的学术影响力,本文应用CNKI中《中国期刊全文数据库》和《中国引文数据库》网络版作为统计源,采用文献计量学方法对《中文核心期刊要目总览》2004年版确定的我国9种情报学核心期刊2001-2003年共190期载文的被引状况进行了统计与分析,以期为后继研究提供参考。 相似文献

本文借鉴文献计量学的方法,利用我国灵长类学文献的各种特征,定量地描绘我国灵长类学研究结构,反映我国灵长类学研究状况.结果表明,动物学研究等8种期刊是我国灵长类学研究的核心期刊.我国灵长类学研究分为:起步、停滞、恢复与发展及持续发展4个阶段,持续发展阶段集中了总文献量的89%,是我国灵长类学研究发展的重要阶段.对我国17种灵长类动物(包括所有特有种)作过研究,其中对Macacamulatta的研究最多;研究学科以生理学、形态与解剖学、生态与行为学、饲养学为主(占总文献量的82%);猕猴属Macaca在各学科研究中都占重要地位.目前我国灵长类学研究在学科及物种方面都不平衡,有必要增加对较薄弱的学科、灵长类种类研究的投入,使它们能共同发展. 相似文献

百泉药会起源于隋代兴起的卫源庙会,清初演变为全国性药材大会;清代百泉药会虽然历经多次迁会风波,但在各界有识之士的鼎力相助下,仍旧不断发展壮大;道光年间的辉县知县周际华相当重视度量衡管理,颁布了与度量衡管理有关的禁令。 相似文献

ABSTRACTThe surface texture of a stone represents a sensitive parameter in evaluating its conservation state. In monuments and sculptures, in fact, external agents continuously alter the appearance of stones, determining peculiar weathering patterns and modifying properties such as retention of water and particles, interaction with light, color, and finishing. The application of protective coatings also determines changes in surface appearance of a stone, usually evaluated and monitored by color change tests. Surface metrology methods offer the possibility to quantify these changes, evaluating the impact of external agents (natural, i.e. weathering, and artificially, i.e. protective coatings) on natural stones. In this research, we demonstrate the potential of surface areal measurements in describing the evolution of weathering processes and the effects of protective treatments on porous stone materials. The obtained results suggest that the extent of the modifications is related to the scale of observation (small- vs. large-scale undulations, i.e. roughness and waviness, respectively), with an overall increase of surface roughness as the weathering proceeds. Unexpectedly, coatings based on nanoparticle dispersions increase the topographic height parameters, due to the absence of a homogeneous film. 相似文献

One of the more frequent activities in health sciences is the measurement of biological quantities. Frequently, when reading biomedical books and journals some confusion on the metrological meaning of biological quantities related to the concepts ‘concentration’ and ‘content’ may be observed. Classically, a concentration is an amount of any type per volume of liquid or gas system, whereas content is an amount of any type per mass of liquid or gas or solid system. However the concepts ‘concentration’ and ‘content’ alone are still ambiguous because, depending on the type of amount of the component (analyte) per volume or mass of a system, there are different types of concentrations and contents. This article attempts to give a clarification of these concepts, mainly based on international recommendations about nomenclature and terminology of metrology, chemistry and clinical laboratory sciences. 相似文献
