学术论文摘要模糊限制语对比研究——以工科与社科中文期刊文献为例
A Comparative Study of Hedges in Academic Paper Abstracts—Based on Natural and Social Science Academic Paper Abstracts
 [PDF]

, 孙飞凤
Modern Linguistics (ML) , 2014, DOI: 10.12677/ML.2014.23015
Abstract:
本文选取发表于2012~2013年工科与社科类各50篇中文学术论文摘要为分析对象,对比研究两类摘要写作中模糊限制语的种类、使用频率及语用功能并阐释其规律及原因。研究表明:两类摘要均含大量模糊限制语,且以变动型为主。无论是程度类或者是范围类模糊限制语,在工科类摘要中的使用频率均略低于社科类。工科类学术论文摘要中,模糊限制语多用于缓和语气,在社科类中则相反,但这些词汇本身所具有的模糊意义在两类摘要中是大体相同的。此外,模糊限制语使学术论文摘要更加规范、严谨、准确,一定程度上体现了合作原则和礼貌原则,同时也体现了论文作者的自我保护意识。
Selecting 100 abstracts from Chinese academic papers on natural science and social science (re-spectively 50) as analytic targets, this paper attempts to make a comparison on the classification, frequency, and pragmatic functions of the hedges in these two kinds of abstracts, and elucidates their rules and reasons. The findings show that there exist a large number of hedges in these two kinds of abstracts, chiefly presented as approximators. Among them, the frequency of adaptors and rounders in natural science academic paper abstracts is slightly lower than those in social science academic paper abstracts. Hedges are more often used to mitigate the tone in natural science paper abstracts, and it is opposite in social science, but the vague meanings of these words themselves are generally the same in these two kinds of abstracts. In addition, they make the academic paper abstracts more standard, rigorous, and precise, and to some extent, reflecting the author’s awareness of self-protection while abiding by Cooperative Principles and Politeness Principles.

热带亚热带植物学报 , 2015, DOI: 10.11926/j.issn.1005-3395.2015.03.009
Abstract: 报道了分布于我国广西西南部的兰科(orchidaceae)虾脊兰属(calanther.br.)一新种——弄岗虾脊兰(c.longgangensisy.s.huang&yanliu).该新种与泽泻虾脊兰(c.alismifolialindl.)相似,但根状茎明显,侧面萼片向上反卷,花瓣重叠,唇瓣侧裂片倒披针形、顶端斜截形,中裂片顶端微2裂、基部具数列白色的胼胝体,花粉块棒状而与后者相区别.
用慢病毒载体介导产生绿色荧光蛋白(GFP)转基因小鼠
张敬之,,谢书阳,,,王舒,任兆瑞
自然科学进展 , 2006,
Abstract: 以慢病毒(lentivirus)载体为骨架,携带绿色荧光蛋白(GFP)基因的假病毒,通过小鼠受精卵卵周隙注射,将其感染小鼠受精卵,经移植于假孕母鼠后获得转基因小鼠.应用PCR、荧光显微镜观察和流式细胞仪分析等技术,证明了GFP基因的整合率达到40%以上;实时定量PCR分析结果表明转基因小鼠中GFP基因整合的拷贝数约为40;染色体荧光原位杂交分析结果显示GFP基因在小鼠染色体上的整合是随机的,并通过交配可将外源基因遗传至子代,获得的多整合位点和不同表达水平的转基因小鼠具有明显的实际应用和研究价值.文中报道的慢病毒载体介导的转基因技术为高效制备和选育高表达转基因小鼠品系提供了一种有效的途径.
