A Cognitive Study of Verbal Nominalization in Chinese

名词化通常由其它词类转化而来，最常见的一类是动词，其次是形容词。汉语名词化研究始于二十世纪五十年代。由于汉语是一种缺乏形态标记的语言，这类研究上产生了很多的观点和争议。传统研究主要关注的是主宾语位置动词和形容词的性质问题以及N的V的构式，而忽略了认知因素的影响。近来，许多学者开始从认知语言学的角度来研究汉语中的名词化现象。但是汉语名词化的认知研究还远远不够，许多研究结果还有待进一步的证实和完善。因此，更为深入和广泛的研究是有必要的，而且意义重大。本文的研究对象为汉语中最为普遍的动词名化现象。在前人研究的基础上，本文试图在认知语法的框架下对汉语中动词名化现象做一个全面的阐述，主要考察了汉语中的两...Nominalization is often derived from other classes, most commonly from verbs and secondarily from adjectives. Studies on nominalization in Chinese didn’t begin until the 1950s. Due to the absence of explicit morphological markers for grammatical categories in Chinese, Chinese scholars have different views and great debates on nominalization in Chinese. Traditional studies mainly focus on the two m...学位：文学硕士院系专业：外文学院英语语言文学系_英语语言文学学号：1202008115285

Experimental Study on Effects of Hypoglycemic and Antiobesity of L-Arabinose in New Zealand Rabbit

目的探讨l-阿拉伯糖对动物(新西兰兔)降血糖和减肥的作用。方法以高糖高脂饲料诱导新西兰兔肥胖模型,然后将其随机分为4组:模型对照组及l-阿拉伯糖低剂量(0.3085g/kg)、中剂量(0.617g/kg)、高剂量(0.9255g/kg)3个给药组。连续喂养2个月后,空腹12H,各给药组按剂量口服l-阿拉伯糖后2H,分别口服蔗糖0、0.5、2H测新西兰兔耳缘静脉血糖值;l-阿拉伯糖干预1个月时测体重、进食量和排便量、脂肪指数的变化。结果高、中、低l-阿拉伯糖组空腹血糖与模型对照组存在明显差异(P<0.05),在糖耐量作用中,l-阿拉伯糖各剂量组和模型对照组的曲线下面积(AuC)出现明显差别。在减肥功能的指标中(体重变化、日进食量和排便量、脂肪指数),l-阿拉伯糖各剂量组与模型对照组比较差异有统计学意义(P<0.05),其中l-阿拉伯糖组与模型对照组的脂肪指数具有显著差异(P<0.01)。结论l-阿拉伯糖有明显降血糖和减肥的作用。Objective To research the function of hypoglycemic and antiobesity of L-Arabinose in New Zealand rabbit.Methods Thirty-two New Zealand white rabbits were randomly divided into 4 groups, 8 rabbits in each group.The control group was fed with high fat and high sucrose diet only.L-Arabinose group was fed with high fat and high sucrose diet along with L-Arabinose, the dosage were 0.308 5, 0.617, 0.925 5 g/kg respectively.After fed for two months, all groups were given L-Arabinose, and blood glucose was detected after orally given sucrose 0, 0.5, 2 h.After intervention of L-Arabinose for one month, the data of weight, food intake, stool quantity and the fat index were observed.Results L-Arabinose decreased significantly sucrose absorption, lower the fasting glucose level and the data of area-under-curve (AUC) significantly.Conclusion L-Arabinose proved to be highly effective in preventing the rise of circulating glucose and fat

Diversity of bacterial community structure and its driving factors in three bays of Bohai Sea

[Background] Sustainable development of coastal ecosystem has become one of the most important concerns for people nowadays. Riverine output and anthropogenic interrupt have important impacts on the coastal environment. [Objective] In this study, we collected 12 samples from three transects including Bohai Bay, Liaodong Bay and Laizhou Bay to explore the microbial community and diversity in summer of 2015. [Methods] DNA was extracted from water samples by using DNA extraction kit. Samples were analyzed by Illumina HiSeq sequencing technology. We compared the differences among these three transects according to the analysis results. [Results] The diversity index and rarefaction curves showed significant differences among these three transects. The order of diversity value was Laizhou Bay>Bohai Bay>Liaodong Bay. The distribution of the dominant community was as follows: the proportion of Proteobacteria, Bacteroidetes, Cyanobacteria, Actinobacteria and Planctomycetes in the Bohai Bay was 39.8%, 25.7%, 22.4%, 5.85% and 4.38%, respectively. The dominant community proportion in Liaodong bay was Proteobacteria (37.8%), Bacteroidetes (25.7%), Cyanobacteria (17.8%), Actinobacteria (10.4%) and Planctomycetes (5.64%). While in Laizhou Bay there were only four dominant communities as follows: Proteobacteria (59.0%), Bacteroidetes (17.5%), Cyanobacteria (8.2%), Actinobacteria (7.88%). By using the principal component analysis (PCA) and Heatmap correlation analysis, we found that environmental factors were key roles in controlling the microbial diversity in the Bohai Sea. Among them, the concentration of nitrate was particularly significant according to the Mantel test analysis. [Conclusion] The microbial diversity in the three bays of Bohai Sea was very rich and multifarious. The population structure and species in the Laizhou Bay is the most complex and abundant among these three bays, and then it is Bohai Bay and Liaodong Bay. There was a significant correlation among microbial diversity, environmental factors and the spatial distribution. Above all, this study will provide a theoretical basis for further protection and ecological development of Bohai Sea

鄂尔多斯高原沙地柏液流通量及其影响因子

[目的]分析沙地柏液流通量变化特征及主要影响因子,为沙地植被的保护提供理论依据。[方法]以鄂尔多斯高原沙地植被的优势种沙地柏为研究对象,利用热扩散(TDP)技术监测生长季沙地柏的液流动态,通过相关分析和回归分析等研究其与气象因子的关系。[结果]晴天沙地柏的液流通量为单峰曲线,干旱时为双峰曲线。雨天沙地柏的液流通量为单峰或双峰曲线。晴天沙地柏液流通量的最大值是2.30～23.38 g/(cm~2·h)。沙地柏液流通量对降雨的响应具有1～4 d的时滞。生长季沙地柏液流通量与光合有效辐射、水汽压亏缺、气温和风速均呈显著正相关,而与相对湿度和降雨量呈显著负相关。[结论]鄂尔多斯高原沙地柏的液流通量随天气而变化。太阳辐射和水分是沙地柏液流通量的主要影响因子。建议当地加强对沙地柏灌丛的保护,防止由于过度水分消耗导致的植被退化

Synthesis of Silicalite-1 Membranes on the Surface of Stainless Steel

Silicalite-1 (pure silica MFI) membranes were hydrothermally synthesized on pretreated surface of two common stainless steel materials, i.e., AISI 304 and 316L. XRD and SEM techniques were used to characterize the membranes. Various membrane morphologies can be obtained by adjusting synthesis conditions such as the H2O/SiO2 ratio in the start colloid, the crystallization time and temperature as well as the substrate materials. The silicalite-1 membranes on the stainless steel surface show potential applications for regenerative fuel cooling technology in high speed flight field.Silicalite-1 (pure silica MFI) membranes were hydrothermally synthesized on pretreated surface of two common stainless steel materials, i.e., AISI 304 and 316L.
