汉法“对字结构”对比

语文研究 2009年第3期 22-26页

作者：孟晓琦贾秀英山西大学外国语学院山西太原030006

文章对汉语与法语的"对字结构"作了系统对比。汉法"对字结构"的使用有四点不同:一是介词类"对"的内部成员不同;二是"对字结构"中"对"的宾语成分不同;三是"对字结构"在句中的位置不同;四是"对字结构"与句中其他成分的语义关系不同。

对蓝靛果中花色苷的组成进行鉴定,并对其抗氧化能力进行比较分析。实验以蓝靛果(‘蓓蕾’品种)为原料,采用有机溶剂60%乙醇(0.1%盐酸酸化)溶液,超声辅助提取90 min;利用D101大孔树脂对获得的粗提物进行纯化,之后冷冻干燥制得粉末物质。通过p H示差法和福林-酚法分别测定总花色苷含量和总多酚含量,分别为(353.35±0.79)、(474.01±2.12)mg/g;并用高效液相色谱-质谱联用法对花色苷组成进行鉴定,共发现11种花色苷,其中矢车菊-3-葡萄糖苷为主要花色苷(90.679%)。此外,实验还通过总抗氧化能力测定和2,2’-联氨-二(3-乙基苯并噻唑-6-磺酸)二铵盐自由基、1,1-二苯基-2-三硝基苯肼自由基清除能力测定,比较分析蓝靛果花色苷提取物、矢车菊-3-葡萄糖苷、VC的抗氧化能力,结果表明,3种物质的抗氧化能力排序为:矢车菊-3-葡萄糖苷>花色苷提取物>VC。

汉法反义同词现象的认知识解

法国研究 2020年第1期 105-112页

作者：孟晓琦山西大学外国语学院

反义同词是人类语言的普遍现象,指同一个词同时兼有两个相反或相对的义项,是一词多义的一种特殊体现。认知语言学认为,语言源自人类与客观世界的互动体验,反义同词即是人类对同一事体所具有的对立性特征进行体验和认知加工后的语言表征... 详细信息

反义同词是人类语言的普遍现象,指同一个词同时兼有两个相反或相对的义项,是一词多义的一种特殊体现。认知语言学认为,语言源自人类与客观世界的互动体验,反义同词即是人类对同一事体所具有的对立性特征进行体验和认知加工后的语言表征。本文主要运用认知语言学上的事件域认知模型理论,以事件域各要素间存在的四种不同关系为基准,尝试对汉、法语中的反义同词现象进行阐释对比。

本研究采用田间试验,在某镉污染地区研究石灰调节土壤pH降低稻米镉积累的效果,以降低镉食物链暴露途径的风险。根据RothLime模型试验共设置4个石灰剂量处理(0、2.25、4.50、7.50 t∕ha),种植两个水稻品种。得到如下研究结果:石灰(2.25~7.50 t∕ha)在2018年一次性施用,最高剂量(7.50 t∕ha)的石灰使土壤pH由初始的5.5上调至6.5左右。施用石灰可提高根际土壤pH、降低CaCl2可提取的镉含量和稻米镉含量;籽粒镉含量与水稻成熟期根际土壤中CaCl2可提取的镉含量显著相关;当一次性施用7.50 t∕ha石灰时,水稻籽粒镉含量降低了77%~80%,连续三年稻米镉含量低于我国食品安全标准(0.2mg∕kg),并且产量未受影响。本田间试验结果表明,单次施用CaCO_(3)使土壤pH上调至6.5,能显著降低水稻籽粒镉的积累。
