在《论语》全书中,"问"一共用了1 20次,是使用频率极高的词之一。据杨伯峻《论语词典》,使用百次以上的词有24个:人(名词)(162),也(语气词)(469),子(称呼)(431),不(否定等)(548),之(代词等)(596),仁(道德等)(109),曰(说)(755),乎(介词等)(140),以(介)(152),可(可以)(122),如(动词)(111),有(副、动)(154),而(连)(319),吾(代)(113),矣(语)(202),无(副)(113),为(动)(170),与(动)(119)。连同"问",共25个。其中,虚词就占了一半。有些词如"为""如""有"既虚又实。在纯实词中,仁、知、日、人、言、问等很有趣地组合了一个论语言说的核心语词系统。  相似文献

我们知道,利用等式证明不等式是证明不等式的一种重要思想方法.在不等式中,对于可化为(a/(b+c))、(b/(c+a))、(c/(a+b))(其中a、b、c〉0)的一类对称不等式,若令x=(a/(b+c)),y=(b/(c+a)),z=(c/(a+b))(x、y、z〉0),则x、y、z满足等式(x/(x+1))+(x/(y+1))+(z/(z+1))=1()(1/(x+1))+(1/(y+1))+(1/(z+1))=2()xy+yz+zx+2xyz=1(以下记此三式依次为①、②、③式),这样,利用这几个恒等式.  相似文献

Concern has been expressed about the vulnerability of the ‘academic profession’ as a consequence of threats from productivism, managerialism and the like (Beck and Young, Br J Sociol Educ 26(2):183–197, 2005). I question the apparent self-understanding of academe as a profession. Referring to thinking from higher education (Barnett, High Educ 40:409–422, 2000a; Educ Phil Theor 32(3):319–326, 2000b; Realizing the University in an age of supercomplexity, 2000c; Stud High Educ 25(3):255–265, 2000d; Lond Rev Educ 2(1):61–73, 2004a; Piper, Are professors professional? The organisation of University examinations, 1994; Taylor 1999), and from the sociology of the professions (in particular Evetts, Int J Sociol Soc Policy 23(4/5):22–35, 2003a; Int Sociol 18(2):395–415 2003b; Curr Sociol 54(1):133–143 2006a; Curr Sociol 54(4):515–531, 2006b), I propose that significant shifts in self-understanding and practice are needed for academe to claim a social role as a ‘profession’.  相似文献

The purpose of the current study was to create a typology of facework behaviors in interpersonal conflicts between best friends and relative strangers for Japanese and U.S. participants. In phase I, 286 participants responded to open‐ended questions about the manner in which they negotiated face during a conflict with either a best friend or a relative stranger. The responses of a sample of these respondents ‐16 Japanese, 16 members of ethnic minority groups in the U.S., and 20 European Americans — were categorized using a Q‐sort technique. Fourteen categories of facework behaviors were derived. Validation procedures for the typology were carried out via a cluster analysis resulting in 13 unique clusters: (a) aggression, (b) apologize, (c) avoid, (d) compromise, (e) consider the other, (f) defend self (g) express feelings, (h) give in, (i) involve a third party, (j) pretend, (k) private discussion, (l) remain calm, and (m) talk about the problem. In phase II, 95 Japanese and 61 U.S. Americans rated the appropriateness and effectiveness of behaviors from each of the categories. The findings illustrate that the typology captures a wide range of appropriateness and effectiveness rating which further demonstrates the validity of the typology.  相似文献

Imprinted polymers were prepared for selective removal of Cu(Ⅱ) ions from metal solutions. Three ion-imprinted polymers were synthesized with methacrylic acid (MAA), acrylamide (AA) and N,N'-methylenebisacrylamide (MBAA) respectively as the functional monomers, ethleneglycoldimethacrylate (EGDMA) as the cross-linking agent, 2,2'- azobisisobutyronitrile (AIBN) as the initiator and Cu (Ⅱ) ion as the imprint ion. The template Cu (Ⅱ) ion was removed from the polymer by leaching with a liquid of a 1:1 volumetric ratio of HCl to ethylenediaminetetraacetic acid (EDTA). The capacity and selectivity of Cu(Ⅱ) ion adsorption were investigated with the three imprinted polymers and their non-imprinted counterparts. The polymers have a maximum adsorption capacity at pH 7.0. The isotherm of their batch adsorption of Cu(Ⅱ) ions shows a Langmuir adsorption pattern. Imprinted polymers all have a much higher capacity and higher selectivity of Cu(Ⅱ) adsorption than nonimprinted ones. MAA polymer benefits the most from imprinting. Imprinted MAA polymer has the highest selectivity when used to rebind Cu (Ⅱ) ion from an aqueous solution in the presence of other metal ions. Ion imprinting can be a promising technique of preparing selective adsorbents to separate and preconcentrate metal in a medium of multiple competitive metal ions through solid phase extraction (SPE).  相似文献

江蓝生 《中国语文》2012,(4):291-308,383
本文所谓连—介词是指能够兼做并列连词的介词,汉语的连—介词至少有四个来源:(1)伴随义动词"和、跟、同"等;(2)使役义动词"唤、教";(3)给予义动词"与、给";(4)同位结构"我两个"中的数量词"两个"。文中描述了这四类连—介词语法化的动因和路径,归纳了它们语法化的三种类型;对相关的语言现象进行了具体的考证和解释;结合论题,对语法化的普遍规律进行了一些概括和说明。  相似文献
