Analysis and teaching strategies of confusion words learning among intermediate Chinese learners in Thailand [PDF]

open access: yes, 2016
2013我在泰国当汉语家教时,接触了大量的泰国学生写作,在修改这些作文的过程中,发现学生的词语误用是最明显的,远远高于语法的使用偏误。大部分词语误用的字会在学生的作文中反复出现。这表明学生无法辨析词语的意义和用法而发生了词语使用上的混淆,而且这种现象还是群体性的,值得去做一下具体分析。同时,通过对HSK动态作文语料库泰国学生书面语语料的分析,我发现中级阶段的泰国学生在对汉语词语的理解和使用方面存在着偏误最多,严重限制了泰国学生提高的汉语水平。由于汉语词汇的用法具有灵活性 ...

小鼠心源性CD51阳性细胞的分离与鉴定

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2014
摘 要: 【目的】 探讨整合素蛋白αv(CD51)阳性细胞在小鼠正常心脏组织中的分布情况并鉴定其是否存在心肌干细胞相关特性。【方法】 通过免疫荧光染色,RT-PCR,Q-PCR等方法,观察CD51+细胞在C57小鼠心脏中的表达及分布情况;应用流式细胞仪进一步检测心脏中CD51的表达比例,并分选出CD51阳性细胞进行体外培养;利用CCK-8实验检测细胞增殖能力;细胞稳定传代后进行成骨、成脂诱导,检测其多向分化能力。【结果】实验结果显示小鼠心脏中存在CD51+细胞,随年龄增大其表达水平呈下降趋势;在出生7d
