论“志”的语素化     

陈练军 《四川师范学院学报》2010,(2):33-39

＂志＂从古至今经历了语素化演变,即由自由成词语素演变为黏着的构词语素。这一变化主要表现在两方面：句法层面,单音词＂志＂的自由度从南北朝开始逐渐下降,到清代完全黏着化;词法层面,＂志＂作为构词语素构词力逐渐发达。是双音化推动了＂志＂的语素化进程。  相似文献   

“政教合一”与“政教分离”——知识政治学视阈中的中古中西政治形态差异     

张庆服 《济宁师范专科学校学报》2010,31(1):98-103

“政教合一”与“政教分离”两种对立的政治结构模式,是中古时期中国与西欧政治形态差异的集中体现,二者本质差异在于关于政权的道理及其确证的区别,其本质差异的深刻原因便是二者拥有的知识基础不同。  相似文献   

Toxic effects of Litsea elliptica Blume essential oil on red blood cells of Sprague-Dawley rats     

Izatus Shima Taib  Siti Balkis Budin  Seri Maseran Siti Nor Ain  Jamaludin Mohamed  Santhana Raj Louis  Srijit Das  Sulaiman Sallehudin  Nor Fadilah Rajab  Othman Hidayatulfathi 《Journal of Zhejiang University. Science. B》2009,10(11):813-819

Litsea elliptica Blume leaves have been traditionally used as medicinal herbs because of its antimutagenicity, che-mopreventative and insecticidal properties. In this study, the toxic effects of L. elliptica essential oil against Sprague-Dawley rat's red blood cells (RBCs) were evaluated. L. elliptica essential oil was given by oral gavage 5 times per week for 3 treated groups in the doses of 125, 250, and 500 mg/(kg body weight), respectively, and the control group received distilled water. Full blood count, RBC osmotic fragility, RBC morphological changes, and RBC membrane lipid were analyzed 28 d after the treatment. Although L. elliptica essential oil administration had significantly different effects on hemoglobin (Hb), mean cell hemoglobin concentration (MCHC), mean cell volume (MCV), and mean cell hemoglobin (MCH) in the experimental groups as compared to the control group (P<0.05), the values were still within the normal range. L. elliptica induced morphological changes of RBC into the form of echinoeyte. The percentage of echinocyte increased significantly among the treated groups in a dose-response manner (P<0.001). The concentrations of RBC membrane phospholipids and cholesterol of all treated groups were significantly lower than those of control group (P<0.001). However, the RBC membrane osmotic fragility and total proteins of RBC membrane findings did not differ significantly between control and treated groups (P>0.05). It is concluded that structural changes in the RBC membrane due to L. elliptica essential oil administration did not cause severe membrane damage.  相似文献   

Morphological and orthographic effects on hemispheric     

Zohar Eviatar  Raphiq Ibrahim 《Reading and writing》2004,17(7-8):691-705

We tested the effects of morphological and orthographic differences between English, Hebrew, and Arabic on the functioning of the two cerebral hemispheres. University students who were native speakers of each of the three languages performed a lateralized consonant-vowel-consonant (CVC) identification task. The stimuli were presented vertically in three conditions: left visual field (LVF), right visual field (RVF), and bilaterally (BVF). Three dependent measures were used: (1) exposure duration of the stimuli in order to achieve a 50% error rate, (2) total number of errors in each presentation condition and (3) the difference between errors on the first letter and errors on the last letter, a qualitative measure of sequential processing. Arabic readers required longer exposure durations of the syllables in order to achieve a 50% error rate than Hebrew readers, who in turn, required longer exposure durations than native English readers. Readers of all three languages evinced left hemisphere specialization for this linguistic task and a bilateral advantage. The qualitative patterns revealed that the Arabic and Hebrew speakers showed the same hemispheric difference pattern, that was different from the one shown by English readers, and that Arabic readers showed a qualitative pattern suggesting higher levels of sequential processes in both hemisphere than readers of Hebrew and English. We interpret this as reflecting the adaptation of hemispheric abilities to reading languages that differ in morphological structure and orthography.  相似文献   

现代汉语连动结构方式构词研究   总被引：3，自引：0，他引：3  

洪淼 《徐州师范大学学报(哲学社会科学版)》2004,30(3):57-60

在现代汉语中,连动结构方式的复合词是指由两个动词语素构成,并且动词语素按照所表示的动作先后顺序排列,两个动词语素之间具有一定的语义关系。连动结构方式构词与其他构词法有一定的区别,连动词可以采用"v1 之后再 v2"的格式来验证。  相似文献   

医学形态学手机移动自主学习平台构建研究     

吴鹏  胡继礼 《教育教学论坛》2019,(24):47-49

手机移动学习因其学习的自主性、时间的开放性、信息的交互性、评价的及时性,无疑是学生自主获取知识的最佳方式之一。目前,国内专家学者对智能手机这种移动平台的建设主要集中在商业领域,将移动学习与具体课程联系研究多集中在英语、文化教育等公共课程,尚缺乏医学专业课程。本文在分析构建医学形态学手机移动自主学习平台的可行性、优点及功能特点的基础上,研讨构建医学形态学手机移动自主学习平台。  相似文献   

电子文件管理元数据词类结构及词类结构体系研究     

张茜 《中国图书馆学报》2008,34(4)

电子文件管理元数据作为描述资源的工具正越来越多地被电子文件管理工作所使用。电子文件管理元数据是一种语言,同其他语言一样,在词汇的层面上具有词的类别。电子文件管理元数据词类结构体系可以分为基本体系与扩展体系。充分认识电子文件管理元数据词类结构和词类结构体系,对于建立我国电子文件管理元数据标准具有重要指导意义。  相似文献

利用RAPD分子标记评价仲彬草属的种间关系     

周永红  郑有良  杨俊良  颜济  贾继增 《中国科学院研究生院学报》2000,38(6):515-521

利用随机扩增多态性DNA(RAPD)技术分析了14种仲彬草属Kengyilia植物的种间关系。对34个OPRON公司十聚体随机引物进行多态性筛选,20个(58．8％)能产生多态性。14个引物产生的112个DNA片断,用于计算种间Jaccard遗传相似性系数分析,在NTSYS程序中利用UPGMA构建系统发育树状图。分析结果表明：(1)14个Kengyilia物种存在较大的遗传多样性;(2)青藏高原的物种与新疆的物种 的RAPD变异极大;(3)形态相似、地理分布一致的物种有一定的亲缘关系,聚类在一起;(4)RAPD结果与形态学和细胞学等分析结果一致。RAPD分析方法将为Kengyilia系统分类提供DNA水平上丰富的资料。  相似文献
