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

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

美国心理学家阿希做过一个有趣的实验:“在甲卡片上画一条线段x。在乙卡片上画三条长短不一但差异甚微的线段a、b、c。其中b线段等于x。这时,如果有8个人故意说a等于x,那么第9个人虽然也看出b等于x,但因前人都说a等于x。于是他便怀疑自已了,也说a等于x。阿希把这种盲目地顺从别人判断的现象称之为“从众现象”。我国古人也曾多次指出“从众现象”之弊:夫市之无虎明矣,然而三人言而成虎”, 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

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

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

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

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

Chromebooks and the G Suite group of products, like Google Search, Gmail, and Google Docs, have rapidly expanded in American schools during the past 5 years. The impact of one-to-one Chromebook devices and the pervasive use of Google's software products in American education cannot be overstated. This article explores some of the influences of these products on research, based on the experiences of a librarian and technology coordinator at an elementary education level. The author has several suggestions for effective research with these products in mind. 相似文献

Library historians can learn a great deal from studying the gender of authorship and institutional affiliation of a scholarly journal. The focus of this study is to examine these two aspects of journal production in library history to see who is producing published research in this field. Twenty-three years of Libraries & Culture were chosen as the target volumes. The study reveals that more men than women published in library history as well as locating which institutions were represented. This type of information is usedful to the library historian engaged in the analysis of published scholarship, and more generally to scholars with an interest in patterns of literature production in fields closely related to the social and behavioral sciences. 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
