在中国知网以“光照强度”为检索词，对2020—2022年发表的300篇生物学论文进行统计，发现单位为lx、μW/cm2和μmol/(m2·s)的不同量却均以光照强度相称，误用比例高达88.67%。通过搜索GB/T 3102—1993《(所有部分)量和单位》、全国名词委官方网站的“术语在线”和百度文库，对光照强度的3种误用表现逐一溯源辨析，可知以lx为单位的量有明确的标准量名称，即“[光]照度”;单位μW/cm2对应的量名称为“辐[射]照度”,若论文中要强调是做光照辐射处理，可加上修饰词“光”以“光辐[射]照度”来表达；以μmol/(m2·s)为单位的量可与标准量“光子照度”对应，由于其多出现在植物光合特性研究的论文中，为体现行业特征，宜以“光合摩尔光子照度”或“摩尔光子照度”来表达。 相似文献

答 须要.然而,在目前的科技文献中,量名称“运动粘度”“[动力]粘度”使用得较多,现行有效的国家标准GB 3102.3-1993《力学的量和单位》中也是这样写的,因此,一些编辑同人对一定要改为“运动黏度”“[动力]黏度”表示困惑不解. 相似文献

放射性活度浓度(radioactive concentration),定义为样品的放射性活度除以该样品的体积,其符号国家标准中未作规定,《核工业化学常用计量单位》[1]中给出的为CA,其SI单位为Bq/m3,常用单位Bq/L。质量活度(massic activity)或比活度(specific activity),GB3102.9—1993[2]中的定义为样品的放射性活度除以该样品的总质量,符号为a,SI单位为Bq/kg。 在各种媒体包括科技期刊中,经常有人将这2个物理量混淆,造成错用或误用。 例如:“2006—2009年的第一次全国污染源普查结果显示,铁矿石中238U、232Th、226Ra的平均活度浓度分别为270 Bq/kg、68 Bq/kg、288 Bq/kg,而煤中238U、232Th、226Ra的平均活度浓度分别为383 Bq/kg、51 Bq/kg、212 Bq/kg。”[3]由使用的单位“Bq/kg”来看,该处的“活度浓度”应该指的是“质量活度”或“比活度”,属于量名称错用。 又例如:“调查结果显示……活度浓度平均值为0.1 Bq/m3、0.6 Bq/m3;……平均活度浓度分别为386、793、3.0、36、48、548 Bq/kg。”[4]前半句中的“活度浓度”使用正确,后半句错了,从单位即可看出应是“质量活度”或“比活度”。同一句中,对不同的单位使用了同样的量名称,属于明显误用。 其实,从以上2个量的定义可明显看出其区别:一个除以体积,一个除以质量,因此,通常放射性活度浓度用于液体或气体,而质量活度或比活度用于固体。在使用这2个量时一般都会写出其量值(数值×单位)。结合上下文内容,分析量值,就可简单快捷地对两者进行辨析,避免错用、误用。 相似文献

在农林科技期刊中频频可见“日照时数”这个量名称,其定义为：一天内太阳直射光线照射地面的时间,以小时为单位。这里,“时数”是按“单位（[小]时）＋数”的错误套式构成的时间的名称,如同以“摩尔数”错作为物质的量的名称一样,显然是不正确的。 相似文献

《图书编校质量差错认定细则》(以下简称《细则》)的第二条规定:“自然科学名词正误的判别,以1990年国家科委、中国科学院、国家教委、新闻出版署联合发布的《关于使用全国自然科学名词审定委员会公布的科技名词的通知》(以下简称《公布名词》)为依据。量和单位正误的判别,以993年国家技术监督局发布的国家标准《量和单位》(GB3100～102—1993)为依据。”根据以上规定,在编辑工作中发现,在《量和单位》中的一些量的名称,与《公布名词》中作为科技名词时名称不同。本文以几个常用词为通过表1可以看到,《量和单位》中的两个量“[动力]粘度”… 相似文献

<正>一、“可及性”理论回溯“可及性”源于拉丁语“Accessus”，首次出现在美国学者Anderson在1968年关于卫生服务“Using Service”的论述中[1]。Anderson认为，“可及性”即“受众对服务的实际享用量及获得服务的便捷或受阻程度”[2]。1981年，洛伊·潘查斯基(Penchansky)和威廉·托马斯(William Thomas)深化了“可及性”涵义——从最初的服务对象单方考量，拓展为服务供求双方的“匹配(fit)”[3]。1999年联合国人权委员会委员塔琳娜·托马斯瑟夫斯基(Katerina Tomasevski)提炼出Availability、Accessibility、 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

ABSTRACTIn today's current political environment raising support for millage renewals, bond campaigns or even millage continuations for public libraries is affected by national politics, and a tendency towards tax aversion on principle across the country. The lessons we can learn from the governing boards of small and rural public libraries are worth raising up to a greater national consciousness. Board governance, community consciousness, and facilities management are clear and logical tools that elected boards of public libraries can use to politick for support of libraries. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

ABSTRACT The history of the almanac in Croatia is reconstructed through primary research in bibliographic and archival sources. The almanac is a vehicle for knowledge communication in informal contexts, engaging both oral tradition and literary forms traceable to medieval literacy and ways of structuring knowledge. The history of the almanac in Croatia reflects the changing context of the book trade, literacy, and the evolution of language. Four main stages are identified: (1) the beginning of the annual almanac in the seventeenth century; astrological almanacs reflecting the sensibility of the Baroque period; (2) the Enlightenment's stimulation of almanac publishing in the spirit of contemporary secular reforms in agriculture and education; (3) nineteenth-and twentieth-century almanac trade, showing complex and overlapping networks for the production, distribution and appropriation of printed almanacs;(4) roughly the end of World War II, when the almanac slowly moved out of the role of a popular mass medium and into specialized niches represented by regional, diaspora, and religious almanacs. 相似文献

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers. 相似文献

ABSTRACTGerman authorities are expecting more than 1 million refugees by the end of 2015. These people come to Germany to seek protection and assistance and to build a new life, therefore it is important to welcome them and to assist them in their integration as soon as possible. This situation creates a versatile and perfectly fitting opportunity for cultural and educational programs, including libraries, which can play a vital role in this integration process. The key to integration is the knowledge of the German language, and the most important challenge now is to teach the necessary language skills to as many asylum-seekers as possible. 相似文献

Abstract Many libraries use RSS to syndicate information about their collections to users. A survey of 65 academic libraries revealed their most common use for RSS is to disseminate information about library holdings, such as lists of new acquisitions. Even though typical RSS feeds are ill suited to the task of carrying rich bibliographic metadata, great potential exists for developing applications that can exploit metadata exposed to Web services via RSS. Using the MODS metadata format, entire catalog records can be seamlessly embedded in RSS 2.0 feeds. Existing tools, such as Library of Congress Java toolkits and XSLT stylesheets, can facilitate this process, while a new XSLT stylesheet may be used to create the RSS feeds complete with MODS records. As an example of the added functionality these MODS/RSS feeds can offer, records from a MODS-enriched RSS feed can be ingested into a non-RSS application such as Zotero. As more emerging library technologies use Web services architectures to handle data objects, the ability to syndicate catalog records will become more critical to providing innovative library Web services. 相似文献

This essay investigates key moments in the history of personal digital assistant (PDA) marketing to women. Analyzing promotional texts for three PDAs that received considerable press coverage from 1999 to 2001, this essay explores the cultural significance of the convergence of anxieties about women's place in the gendered division of labor with the computer industry's changing marketing imperatives. Drawing on an array of promotional texts, including news articles, press releases, promotional Web sites, and ads appearing in newspapers and magazines, this paper tells the story of how the computer industry aimed to sell smaller, faster computing devices to women while promising to mediate and thus reproduce women's overwork as paid and familial laborers. After experimenting with the PDA as a sexy fashionable gadget for working women, marketers approached women as mothers with “Audrey,” an Internet appliance designed for the kitchen. 相似文献

This study explores the attitudes and actions of bank managers toward communication spending during recession. Results of this study indicate that organizational leaders cut communication spending early during recession and also erroneously rely on the bank's financials to mitigate irrational customer withdrawals. This research is used to illustrate the need for public librarians to meet the needs of bank stakeholders when their institution ceases to communicate during crises, for academic librarians to educate students in undergraduate and graduate programs regarding heightened information needs during recession, and for corporate librarians to understand a potential avenue for competitive advantage during recession. 相似文献
