《现代汉语词典》中四字格异形成语分析

异形成语是意义相同而书面形式不同的两个或两个以上的成语。异形成语的意义相同是指成语整体的隐含的意义相同,它们的书面形式不同但在形式上又具有一致性。《现代汉语词典》中收录的四字格异形成语的构成情况复杂。根据其成因可分为五种类型:置换字词类、调整词序类、改变说法类、增减字词类、综合变化类。这五大类又分别可以根据不同情况分为若干小类别。     

A study of Platyplectrus Ferrière (Hymenoptera: Eulophidae) in mainland China

This paper reviews the Chinese species of Platyplectrus Ferrière. Twelve valid species are recognized from mainland China and a key to species is provided. Trichoplectrus Erdös (1951 Erdös, J, 1951. "Eulophidae novae. Acta Biologica". 1951, Academiae Scientiarum Hungaricae, 2(1–3), 169–237. [Google Scholar]) is newly synonymized with Metaplectrus Ferrière (1941 Ferrière, C, 1941. New species of Euplectrini (Hym. Chalcidoidea) from Europe, Africa and Asia, Bulletin of Entomological Research 32 (1941), pp. 17–48.[Crossref] , [Google Scholar]) and three new combinations are proposed: Metaplectrus szepligetii (Erdös) from Platyplectrus, Platyplectrus bussy (Crawford) from Euplectrus and P. politus (Lin) from Metaplectrus. Four species of Platyplectrus were known previously from China: P. politus (Lin), P. odontogaster (Lin), P. papillata Lin and P. medius Zhu and Huang. Six species, P. bussyi (Crawford), P. laeviscuta (Thomson), P. natadae Ferrière, P. orthocraspedae Ferrière, P. pannonica (Erdös) and P. viridiceps (Ferrière) are newly recorded from China and re-described. Five new species, P. pulcher, P. setulosus, P. peculiaris, P. obtusiclavatus and P. variflagellum are described and compared with related species. Several species are also newly recorded from other regions: P. orthocraspedae Ferrière from the Afrotropical region, P. bussyi (Crawford) and P. laeviscuta (Thomson) from the Australian/Pacific region, P. laeviscuta (Thomson) from the Oriental region and P. viridiceps from the Palearctic region.     

Revision of the genus Mimopodabrus Wittmer (Coleoptera,Cantharidae)

The genus Mimopodabrus Wittmer is reviewed, and the genus diagnosis is re-described. Three new species are described, M. multidentatus sp. nov. (Guangdong, China), M. variabilis sp. nov. (Yunnan, China) and M. diversefoveolatus sp. nov. (Lao Cai, Vietnam), with illustrations of habitus, antennae and aedeagus. A species is transferred from Micropodabrus to this genus, M. bicoloriceps (Wittmer, 1989 Wittmer, W. 1989. 42. Beitrag zur Kenntnis der indo-malaiischen Cantharidae und Malachiidae (Coleoptera). Entomol Basil., 13: 209–237.  [Google Scholar]) comb. nov. A species is synonymized, M. bicoloriceps (Wittmer, 1989 Wittmer, W. 1989. 42.

A key to all known species of this genus is provided.

基于语料库的英汉语词汇互译研究

通过例证,探讨了如何利用语料库进行汉语词汇英译、英语同义词词义区别、译语对等词的抉择、词;12搭配的确定等问题;实践表明：借助现代化设备自建翻译语料库开展的词汇互译研究,相比于借助传统词典具有速度快、检索方便、例证更丰富,语料更翔实等特点,也更能体现出专业特色来。     

融合与创新：“村改居”社区文化建设路径探讨

社会转型以来,在工业化、城市化进程的推进下,“村改居”工程普遍实施,“村改居”社区数量激增。与此同时,经历突然制度变动和身份转换的农民出现一系列不适反应,“村改居”社区自身的治理与发展也陷入困境。究其根源,是社会急速转型过程中由文化堕距衍生出的价值规范断裂和传统与现代冲突所致。基于此,打破传统熟人社会中维系人际关系的血缘纽带,重构现代社区文化建设要求的“契约式”融合,通过完善社区服务和健全社区保障创新社区文化建设手段来推进社区文化顺利转型应不失为“村改居”这种过渡型社区文化重建的现实路径。     

The species of Symplocodes Hebard (Blattodea: Ectobiidae: Blattellinae) with description of a new species from China

This paper provides a generic diagnosis, a species list and taxonomy for the genus Symplocodes Hebard, 1929. The new species Symplocodes euryloba sp. nov. from China is described and illustrated. Symplocodes tsaii Bey-Bienko, 1958 is regarded as a subspecies of Symplocodes marmorata (Brunner von Wattenwyl, 1893), i.e. S. marmorata tsaii comb. nov., and its differences from S. marmorata marmorata (Brunner von Wattenwyl, 1893) are discussed. Two known species, Symplocodes ridleyi (Shelford, 1912) and Symplocodes manubria Feng et Guo, 1990, are redescribed and illustrated, whereas one new specific synonym, i.e. Symplocodes brachialis, is proposed. A key to species worldwide is provided. The tarsal claws of these four species as well as one species of Chorisoserrata Roth, 1998 are examined and photographed to compare the intergeneric differentiation of claw specialization and to discuss its function.     

基于查询日志分析的中文网页关键词抽取方法

以全文索引为基础的网页搜索引擎检索相关度偏低。针对这一问题,本文提出了一种基于查询日志分析的中文网页关键词抽取方法。该方法利用用户对网页与查询词的相关性判断来选择关键词。为了量化用户的相关性判断,提出了单位篇幅停留时间、逆向点击率、排名补偿因子3个指标,并对其进行综合加权。在查询串分词、同义词识别及多义词消歧、关键短语组配方面,也做了特殊处理。实验结果表明:抽取关键词的准确率较高,综合性能也高于TF.IDF和SVM方法。该方法能得到较满意的关键词抽取效果。
