在古汉语中一般用“荷”、“任”、“擔”、“挑”、“担”、“扛”、“揭”表示现代汉语中的“肩负”义。先秦时期,一般用“荷”和“任”;汉魏时期,“擔”字用例逐渐增多;宋时开始,用“挑”“扛”“担”表示这一意义;明清时期,“担”、“扛”、“挑”取代了“荷”、“揭”和“任”。 相似文献

从“生X的气”看离合词离析格式的演化过程 总被引：1，自引：0，他引：1
从词汇化角度分析"生气"等离合词及其相关格式"生X的气"的产生过程,指出"生X的气"等的来源基础是"吃X的醋"格式。产生的机制是在词汇化与去词汇化的两种演变过程中,汉语整合造词造句和类推的结果。 相似文献

清华简《保训》述及舜"求中"、"得中",上甲微"假中"、"归中",论者说以中道。借助对有关记载的中、中和、中正、中庸及相关的极、皇极诸概念的比证分析,可知中乃一内涵极为丰富的政治伦理概念,代表了中国古代的治道理想,其义当从三代的河洛文化背景内寻绎。"保训"当读为"宝训",但绝非"珍贵的训诫"。宝者以道为贵宝,其义存于《逸周书·宝典》所记载武王对周公的训谕之中。 相似文献

本文通过研究表明:本文用完全双列杂交对五品种肉兔:加州兔(C)、新西兰兔(N)、丹麦白兔(D)、花巨兔(G)、比利时兔(B)进行了一般配合力(GCA)和特殊配合力(SCA)分析,估计了杂交组合的杂种优势率(RH),结果表明:半净膛、全净膛屠宰率在父本中差异不显著,在母本则有极显著差异。多重比较方法分析所得半净膛、全净膛屠宰率在母本中高低依次为新西兰兔、花巨兔、比利时兔、丹麦白兔、加州兔,其中新西兰兔、花巨兔的母本的半净膛率分别极显著(P<0.01),显著高于丹麦白兔和加州兔。因此,新西兰兔母本最好,加州母兔最差。特殊配合力分析两指标互作效应均不明显,杂交无优势。肉质性状间普遍存在一定的表型相关,但多数未能达到0.05的显著水平。pH2L与pH2S有显著的强正相关(P<0.05);对于胴体性状而言,全净膛屠宰率、半净膛屠宰率为极显著的强正相关(r=0.985,P<0.01)。肉质性状和胴体性状之间存在弱负相关,因此,总体上讲肉质与胴体性状间的关系表现为一种颉颃性的相关。 相似文献

Fe(Ⅲ)-2,9,16,23-tertracarboxy-phthalocyanine(Fe(Ⅲ)-taPc)was synthesized.and bonded to polystyrene(PS) with covalence by Friedel-Crafts reaction to form a new polymer(Fe(Ⅲ)-tapC-PS) (polymer(II)),UV-VIS and Infrared spectra indicated that Fe(Ⅲ)-taPc was successfully bonded to PS.A photoreceptor device of sandwich structure consisting of alternate layers of poly-mer(II)and fullerene(C60) was prepared.The experiment results show that the photoconductivity of the photoreceptor is higher than that of the single-layer film of polymer(II) or C60,because of the charge-transfer effect between the layers. 相似文献

目前所知最早韵图为行于宋代之《韵镜》。《韵镜》已经相当成熟,其前唐代究竟有无韵图,至今仍有不同意见;韵图模式如何,尚没有具体论及。敦煌写本《守温韵学残卷》本身的内容反映,它是基于一种韵图而述的,这种韵图与《韵镜》在基本结构上很相同,推知《韵镜》是由它发展来的。释守温是唐末人,其韵学残卷可据以考知唐代韵图及有关门法的大体内容,弥补对这方面了解的不足。唐代等韵图的结构是:三十字母以唇、舌、牙、齿、喉五音为序,各部位基本以清、次清、浊、清浊为序;每栏分四等,区别洪细;四声相承。唐代亦有门法,如音和、类隔、凭切等,为宋代门法滥觞。唐代韵图和门法反映唐代等韵学的水平,包括对音类、音值审辨的精细程度。其中,“重轻”是分辨等第的,与韵母、声母的洪细都有关系。此卷还反映晚唐西北方音,其中有确凿材料反映晚唐轻唇已在轻唇十韵中分化完毕,正齿音二三等相混,正齿音浊塞擦音床与浊擦音禅相混,洪转为细与浊塞擦转为浊擦有关;觉、药合流,职德与陌麦昔锡相近。 相似文献

To describe and facilitate the identification of child school behavior patterns, we developed a typology of child school behavior (ages 6–11 years) using the norming data (N = 2,338) for the second edition of the Behavior Assessment System for Children Teacher Rating–Child form). Latent profile analysis was conducted with the entire data set, whereas cluster analysis was conducted within each latent profile. The resulting classification system included three latent profiles: (a) Adequate Adjustment (AA), (b) Mild Adjustment Difficulties (MAD), and (c) Functionally Impaired Adjustment (FIA). The AA latent profile included the (a) Well‐Adapted, (b) Average, and (c) Worry clusters. The clusters identified within the MAD latent profile were (a) Academic Problems, (b) Physical Complaints, (c) Disruptive Behavior Problems, and (d) Internalizing Problems. Finally, the FIA latent profile comprised the (a) Clinical Problems–External and (b) Clinical Problems–Internal clusters. 相似文献

The current study investigated the content of future perceptions among 47 U.S. women and 48 Israeli women. Thematic analysis was used to explore participants’ qualitative responses. Women’s responses covered a wide range of topics, and were categorized into ten key themes: (a) work, (b) family/relationships, (c) property, (d) residence, (e) education, (f) general quality of life, (g) leisure, (h) pro-social activities, (i) multiple role management, and (j) religion. Results demonstrated the role of nationality in the process of exploration and future perceptions. Implications for research and practice are discussed. 相似文献
