摘要：凌纯声是中国近代著名的人类学家、民族学家和音乐家。虽然他没有对艺术进行过专题研究,但是在他一生的民族志研究中涉及了大量的中国民族艺术,其中包括了他书写的作为中国第一部人类学科学民族志的《松花江下游的赫哲族》,所以凌纯声也可以被认为是第一位用科学民族志方法对中国民族艺术进行研究的人类学家。凌纯声曾留学法国,在《松花江下游的赫哲族》一书中体现了他的老师莫斯的人类学科学研究方法,如今这样的科学研究方法也作为中国人类学的“从实求知”的科学精神被传承,此精神也是中国艺术人类学所同样继承的,并且他从问题意识出发将西方人类学研究方法和理论进行中国化应用的方式,是现在正在大量引入西方理论的中国艺术人类学界应该思考和借鉴的。

摘要：为探究电站尾水边坡在降雨条件下的变形及稳定性,采用有限元计算强降雨条件下边坡的渗流场分布,并将渗流场计算结果导入颗粒流模型中分析。结果表明:受雨水入渗及坡体自身渗流场的影响,坡脚区域首先出现暂态饱和区;随着降雨历时增加,入渗影响范围增大,坡脚处渗流方向发生偏转,方向由竖直向下逐渐转向指向坡内;降雨前中期坡体变形集中在浅表,坡体位移增大区域与暂态饱和区域相同,降雨后期坡体产生了圆弧形潜在滑面,坡体变形呈现出推移式滑坡的特点,而坡脚起到了阻滑作用,因此需要注意坡脚部位的施工支护及排水措施。

摘要：This paper describes parody as an effective teaching and learning practice in Advanced English course offered to English major juniors and seniors. The objective of this course is to help heighten students towards a more advanced level of English proficiency, and its main preoccupation is doing intensive analyses of carefully selected texts which amount to well-established classics and are characterized with linguistic complexity. To enhance students＇ learning, we embed in the course a practice of parody, which here refers to the creation of an imitative work of an original written work, usually with an attendant comic effect. Upon the completion of each module, students are assigned the task of parodying part of the text, which involves recasting its overall content while retaining formal framework, thus offering students a means of re-paying homage to the excellence of the text. Writing a parody demands great artistry in shaping a creatively simulative work, in fitting exotic content into a local form, and in transplanting new experiential logic into old textual order. The parodies are then peer-reviewed as well as instructor-reviewed. Close observation and survey show that the students have displayed heightened motivation in engaging themselves in the practice and they have benefited greatly from it. Parody proves a particularly fruitful technique in teaching and learning Advanced English, and may also be useful in teaching English writing, since it entitles students to a very unique mode of savoring and wielding the artistic power of the English language.

摘要：顺应论从一种崭新的语用视角来考察语言的使用情况,是一个极具解释力的语言学理论。该理论认为,顺应性是人类使用语言的本质特征,这恰巧与动态的翻译过程不谋而合,因此,顺应论对翻译研究有很好的辅助作用。文章以运动广告为例,从语用顺应论视角看此类广告翻译顺应性的体现,从而得出:成功的广告翻译实质是对语言的成功顺应。

摘要：Zeolites of *BEA framework topology containing isomorphously substituted Lewis acidic metal centers catalyze the liquid-phase intramolecular Prins cyclization of citronellal with outstanding catalytic activity and (dia-)stereoselectivity to the commercially most valuable product, isopulegol (IPL). Effects of the metal-center identity and solvent type were occasionally noted, yet without systematic studies hitherto reported. Here, characteristic dependences of catalytic activities and stereoselectivities on solvent and metal identity were uncovered over four M(IV)-Beta catalysts (M = Sn, Ti, Zr and Hf) in four distinct solvents (i.e., acetonitrile, tert-butanol, cyclohexane and n-hexane). Zr^(-) and Hf-Beta were the most active in acetonitrile and the most selective (> 90% to IPL) in tert-butanol, though their activities were generally lower than Ti- and Sn-Beta in solvents other than acetonitrile. By comparison, Ti-Beta was inferior to other catalysts in terms of both activity and IPL selectivity (as previously shown) in acetonitrile but became the most active in other solvents, with markedly increased IPL selectivity from 60% to 70%?80%. Combining multiple site discrimination and quantification techniques, turnover frequencies were determined for the first time in this reaction;such site-based activities, coupled with comprehensive kinetic interrogations, not only enabled a rigorous comparison of catalytic activities across M-Beta catalysts but also provided deeper insights into the free energy driving forces as solvent and metal identity are varied. The activity and selectivity trends, as well as those for the adsorption and intrinsic activation parameters are caused by solvent co-binding at the active site (acetonitrile and tert-butanol) and less quantifiable crowding effects (cyclohexane) due to the limited pore space and the need to accommodate relatively bulky reactant-derived moieties. This work exemplifies how the interplay of metal identity and solvent dete

摘要：伴随依法治国的发展历程,高校越来越强调法治教育的重要性,但由于学科属性不明确,产生了诸多矛盾和问题。通过总结经验,管窥学科属性和发展规律,法治教育应臵于思想政治教育学科范畴,这是实现其阶段性目标和总体目标的关键所在。在此前提下,大学生法治教育要以法治理论源流与传统法文化、法治体系、法治认同等作为基本内容,走专门课程、法治文化、网络空间、社会实践等有效路径。

摘要：无针注射技术是一种利用高速微射流将药液递送进皮下指定部位的新型给药手段。尽管目前无针注射技术已在多个领域得到应用,但针对其药液扩散机制和注射性能的研究仍存在一定的不足。本研究旨在确定无针注射过程中的关键参数,并描述其对注射效果的影响。本文通过小鼠实验的方法,比较了不同注射条件下无针注射器的注射完成率和注射性能。结果表明,相比于其它注射参数,喷嘴直径对射流性能的影响更为明显。此外,注射完成率随喷嘴直径增大而增加,当喷嘴直径为0.14 mm和0.25 mm时,注射完成率分别为89.7%和95.8%。进而,通过对小鼠血糖变化率的分析发现,采用无针注射的方式进行胰岛素给药可以获得超过120 min的药效持续时间,优于传统针头注射方式。综上,本文所得结论可为气动无针注射器的优化设计和拓展应用提供重要参考依据。

摘要：早在上个世纪七八十年代,钱梦龙、魏书生提倡的“三主三式导读法”、“课堂教学六步法”、“四遍八步自学法”等富有独创性、科学性的教学理论与实践模式已经蜚声中学语文界,积极促进了对当时“少、慢、差、费”的语文教学现状的改革。如今,研究他们的语文教学艺术,将对促进新世纪的语文教学改革,全面提高语文教学效率起到重要的作用。
