Medline (PubMed)遗传学杂志文献搜索引擎开发研究 总被引:1,自引:0,他引:1
为了方便遗传学工作者快捷、准确地查阅遗传学杂志文献,开发和利用NCBI 的 Medline数据库的遗传学杂志文献资源。从Medline (PubMed)中检索并列出173种有关遗传学的杂志名录,制作了每种杂志及部分杂志年份相应的超级链接,组成一个有关遗传学杂志文献的搜索引擎。此搜索引擎能快捷、准确、动态地检索173种遗传学杂志全部文献题录及部分杂志各年的文献题录,并可在PubMed中进一步检索出文献的摘要和部分全文。
Abstract:To help geneticists look up genetics journals more quickly and exactly,this paper developed this search engine of genetics journals. The paper exploited the search engine with genetics journals sources of Medline database in NCBI, indexed and listed 173 names of genetics journals from Medline. Then obtained one search engine concerning genetics journals after making every journal´s super linkage. The search engine can search out not only all articles´ titles of 173 genetics journals but also some articles’ titles of the journals each year quickly,exactly and variablely. We can further obtain all articles´ abstracts and some full texts in PubMed. 相似文献

《Cryptogamie Mycologie ☆》1999,20(4):291-302
The present note introduces the scientific achievements of André Maublanc (1880–1958) through a comprehensive biography, a yet unpublished list of his publications and of taxa he introduced grouped following localities of origin. Over one hundred titles pertaining to the fields of phytopathology and mycology were located. These notes of fundamental research are accompanied by titles of several basic and popular books that have been edited several times. These documents consider diseases of cultivated plants grown in temperate or tropical climates, the taxonomy of their fungal agents and of some other saprotrophs. The significant scientific production of André Maublanc and his marked teaching and popular treatises are behind the long established international status of this French naturalist of the first half of the 20th century. 相似文献
