《汉语大词典》有关《潜夫论》并列复词的问题     

徐山 《黄山学院学报》2006,8(1):143-145

东汉王符《潜夫论》中的并列复词相当丰富，出现了许多新词新义。《汉语大词典》在处理《潜夫论》中的并列复词时存在一些疏忽，主要有释义不确、失收词条、漏立义项、书证迟后等四个方面的问题。  相似文献   

解读《英汉翻译例句词典》     

丁志聪 《泉州师范学院学报》2005,23(5):118-123

《英汉翻译例句词典》词目下不列注解只举例句,使读者对“没有上下文,就没有意义”豁然开朗.该部词典从上千部（篇）作品、文献中选出妙句及佳译,揭示了“词无‘定义＇”、“译无‘定法＇”的译学真理,堪称独树一帜、雅俗共赏的翻译词典.  相似文献   

《孟子》的宾语前置   总被引：1，自引：0，他引：1  

郭向敏 《新乡师范高等专科学校学报》2004,18(3):107-109

宾语前置是古代汉语较为突出的特殊句式,与现代汉语形成很大的差异。如果对这种特殊语序辨析不清,就会妨碍对古书文意的正确理解,因此,它历来受到古代汉语语法研究者的重视。对《孟子》中宾语前置现象进行具体分析,有利于理清这一语法现象在该书中的特殊性及其变异轨迹。  相似文献   

浅谈《马氏文通》与现代汉语词类划分标准之比照     

陈燕玲 《闽西职业技术学院学报》2005,7(2):68-70

纵观汉语语法发展史,将《马氏文通》确立的词类划分标准与现代汉语的词类划分标准相比照,结果发现马建忠提出的词类划分标准,即以意义和句法功能为标准,至今仍是现代汉语划分词类的主要标准。由此可见《马氏文通》确立的汉语词类体系及词类划分标准具有相当的科学性。《马氏文通》在汉语语法史上的重要影响亦可见一斑。  相似文献

Representational Issues in Students Learning About Evaporation     

Russell Tytler  Vaughan Prain  Suzanne Peterson 《Research in Science Education》2007,37(3):313-331

This study draws on recent research on the central role of representation in learning. While there has been considerable research on students’ understanding of evaporation, the representational issues entailed in this understanding have not been investigated in depth. The study explored students’ engagement with evaporation phenomena through various representational modes. The study indicates how a focus on representation can provide fresh insights into the conceptual task involved in learning science through an investigation of students’ responses to a structured classroom sequence and subsequent interviews over a year. A case study of one child’s learning demonstrates the way conceptual advances are integrally connected with the development of representational modes. The findings suggest that teacher-mediated negotiation of representational issues as students construct different modal accounts can support enriched learning by enabling both (a) richer conceptual understanding by students, and (b) enhanced teacher insights into students’ thinking.  相似文献   

支持向量分类算法在5-HT3受体拮抗剂的构效关系研究中的应用     

杨善升  陆文聪  纪晓波  陈念贻 《上海大学学报(英文版)》2006,10(4):366-370

In this work, support vector classification （SVC） algorithm was used to build structure-activity relationship （SAR） model of the 5-hydroxytryptamine type 3 （5-HT3 ） receptor antagonists with 26 compounds. In a benchmark test, SVC was compared with several techniques of machine learning currently used in the field. The prediction performance of the model was discussed on the basis of the leave-one-out cross-validation. The results show that the accuracy of prediction of SVC model was higher than those of back propagation artificial neural network （BP ANN）, K-nearest neighbor （KNN） and Fisher methods.  相似文献   

L-ficolin突变体原核表达载体的构建及表达产物的鉴定     

张家忠  李小燕  向田  章晓联 《襄樊职业技术学院学报》2007,6(2):23-26

目的构建L-ficolin突变体的原核表达载体，为研究L-ficolin的糖结合位点奠定基础。方法设计L-ficolin突变体基因上、下游引物，分别引入EcoRⅠ和XhoⅠ酶切位点。以插入L—ficolin M2（Val144Phe）和M6（Glu 307Asp）点突变的完整编码区基因的质粒pCDNA3-L-ficolin为模板，通过PCR扩增获得突变体的基因片段，将其克隆入原核表达载体pGEX—KG．然后通过酶切和序列测定对其进行鉴定；将此表达载体转化入表达菌BL21（DE3）pLvSs诱导表达。并采用SDS—PAGE对表达产物进行鉴定。结果经酶切及序列分析表明．成功地构建了重组原核表达载体pGEX-KG—L—ficolin—M2、pGEX-KG-L-ficolin—M6，SDS—PAGE显示目的蛋白大量表达。结论L—ficolin突变体融合蛋白可以在大肠杆菌中大量表达。为研究L-ficolin的糖结合位点打下基础。  相似文献

Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability     

Walley  Amanda C.  Metsala  Jamie L.  Garlock  Victoria M. 《Reading and writing》2003,16(1-2):5-20

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.  相似文献
