1990年12月18日,国家技术监督局、国家土地局、农业部联合发出<关于改革全国土地面积计量单位的通知>,明确规定我国土地面积的法定计量单位为km2(平方千米)、hm2(公顷)和m2(平方米),同时规定自1992年1月1日起,废除在我国沿用了2 000多年的传统土地面积计量单位"亩"[1].亩与m2、hm2之间的换算关系为1亩=667 m2=0.0667 hm2. 相似文献

农林科技期刊来稿中使用非法定面积计量单位“亩”的现象仍较为普遍 ,为执行科技期刊面积计量单位标准化 ,编辑须将“亩”换算成“ｈｍ2 ”或其他法定面积计量单位。本文在总结“亩”换算成“ｈｍ2 ”或其他法定面积计量单位过程中容易出现差错的基础上 ,提出了避免差错的常用方法及应注意的问题。 一、农林科技期刊中使用“亩”的基本情况 “亩”是我国 1992年 1月 1日起停止使用的非法定面积计量单位[1] 。由于“亩”为我国人民和广大农林科技工作者所惯用等多种原因 ,目前使用“亩”的现象仍然较为普遍。据统计 ,2 0 0 2年《新农… 相似文献

长期以来,我国土地面积一直沿用“亩”(市亩)等市制计量单位,与国际上通用的土地面积单位不一致,换算又十分麻烦。由于土地面积计量单位的改革涉及面广,政策性强,情况比较复杂,国务院在1984年2月27日发布的《关于在我国统一实行法定计量单位的命令》中确定:“农田土地面积计量单位的改革,要在调查研究的基础上制订改革方案,另行公布。”后来,随着法定计量单位的全面推行,长度法定单位“米”和面积法定单位“平方米”以及它们的倍数单位得到广泛应用,现实国家版图、地区疆域使用平方公里,耕地面积、林地、草地面积使用公顷,建筑用地包括农村计算宅基地使用平方米,为改革市制土地面积计量单位创造了条件。 相似文献

国际计量委员会(CIPM)1996年建议,土地面积单位公亩(符号为a)、公顷(符号为ha)为暂时保留与SI并用的非SI单位。1 a=100 m2,1 ha=100 a=104m2。在我国,公顷被选为国家法定单位,公亩则不是,理所当然不应采用词头"h"加非法定符号"a"构成公 相似文献

二、农业科技图书正确使用法定计量单位之探讨１．严格执行国际标准和国家标准法定计量单位是基础学科用先进的仪器设备 ,先进的手段测试出来的 ,同样也适用于农业科学。以上所谈到的许多量和计量单位使用中的错误 ,正是因为没有正确使用法定计量单位所造成的。农业科学同样也应严格执行国际标准和国家标准 ,严格按照法定计量单位的使用规则正确使用计量单位。２．土地面积计量单位的处理“亩”被停止用作土地面积的计量单位已有８年之久了 ,法定的土地面积计量单位是ｈｍ２ 和ｍ２,但在电视、报纸、杂志、图书中都仍在大量使用“亩”来表示… 相似文献

在农业类书稿的编辑加工中 ,经常要碰到“亩产××公斤”、“亩施××公斤肥料”之类的句子。“亩”属于应废除的计量单位 ,因此 ,编辑往往将“亩”换算成“平方米”( 1亩 =666 66…平方米 )或“公顷”( 1公顷 =1 5亩 )。这样换算后虽计量单位符合规定了 ,但却给农民增加了麻烦。由于长期形成的习惯 ,农民对于“亩” ,脑子中有一个具体的可比的概念 ,而对于“平方米”或“公顷”现在还比较陌生。基于这种情况 ,笔者认为 ,在现阶段 ,用“1 / 1 5公顷 ( 1亩 )”表示“亩产”、“亩施”等中的“亩”较好。这种表示方法有两个好处 :一是既符合国… 相似文献

This article surveys a sample of sources of the information about Romania available to British readers in nineteenth century British newspapers and periodicals. It traces first contacts between the Romanian lands and Britain after the union of the principalities of Wallachia and Moldavia in 1859, then after their independence from the Ottoman Empire. The article highlights an increased Romanian interest in British periodicals, which reported and reviewed Romanian literature and scholarship. The article concludes that nineteenth century British newspapers and periodicals offer a great variety and wealth of new material previously unavailable or unknown to researchers. It also states that only a portion of a large quantity of this material has been indexed and is therefore available via the bibliographic sources mentioned in the article. The author argues for the need of a new and updated British-Romanian bibliography, which can draw on new online resources offering access to thousands of new newspapers and periodical records. 相似文献

ABSTRACT The paper looks at library approval plans for material published in Slavic, East European, and Eurasian countries from the selector's point of view. Reasons why a selector would or would not want one are examined. Success with approval plans requires monitoring receipts, as well as good and ongoing communication among the selector, the acquistions department, and the vendor. A preliminary list of vendors offering approval plans for the countries of the region appears in the appendix. 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

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

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
