By adopting quantitative analysis,based on the statements for oral scale of CSE(China Standards of English)level five,this paper investigated the current status,common difficulties and control factors on oral English competency of nonEnglish majors in second-tier universities,which was conducted using questionnaires that includes six dimensions of language expression:accuracy,complexity,coherence,fluency,appropriateness,and *** results showed that:(i)the overall oral English competency of college non-English majors hasn't met the statements of CSE level five;(ii)female students significantly outperformed male students,and business majors students significantly outperformed those in liberal arts majors who were significantly better than those in science majors;(iii)there was no significant difference between grades;(iv)the flexibility,coherence and accuracy of language expression almost reached the standard grade,but the common core difficulties faced by the students were mainly in pronunciation,scope oflanguage expression,fluency and *** goals,less practice and poor vocabulary were major impact *** research is helpful for strengthening students?knowledge on their own oral English competency as well as adjusting their oral practice objectives,thereby shedding light on students5 actual oral English proficiency and helping to clarify and refine the teaching objectives of speaking and promote the effective practice of oral English as well as the rational application of CSE.

A PASSIVATION STUDY OF Ti-MODIFIED Fe—BASE ALLOY SYNTHESIZED BY MAGNETRON SPUTTERING TECHNIQUE

引用

Acta Metallurgica Sinica(English Letters) 1994年第1期7卷 27-30页

作者： LI Huiqin, zhou honghui, YANG Dejun, SUN DongbaiUniversity of Science and Technology Beijing, China

A set of fracture device was designed on the basis of traditional scratching-electrode technology and used to study the passivation process of two magnetron-sputtered stainless sleel coatings (amorphous and crystalline struture). The results of fracture tests in 3.5 % NaCl aqueous solution show that the amorphous alloy has a high bare surface reactivity and a high passive rate in comparison with the crystalline alloy. The effect of structure on corrosion resistance is also discussed. The excellent corrosion resistance of amorphous alloy is considered to be partly attributed to its great passivation ability.

关键词： passivation kinetics amorphous Fe-base alloy coating,corrosion resistance

从师法自然出发,以静态接触角高达140°的箬叶下表面为仿生对象,使用2种模板法制备具有箬叶下表面微纳复合结构的聚合物仿生表面。采用扫描电镜观测聚合物仿生表面的微观形貌,借助接触角测量仪分析仿生表面的润湿性能。以箬叶下表面为模板,采用聚二甲基硅氧烷(PDMS)二次复形方法获得仿箬叶下表面,仅实现微乳突结构的部分复形,而大多数纳米片层结构缺失,其静态接触角与PDMS本征接触角相比只提高了7°左右。采用电铸与注射成型相结合的方法获得的仿箬叶聚丙烯(PP)表面,可基本实现微纳复合结构的复形,其静态接触角与PP本征接触角相比提高了50°以上,进一步采用低表面能的氟硅烷修饰注射成型仿箬叶PP表面,其静态接触角与PP本征接触角相比提高了70°左右,达到了133°±2°。但2种模板法成型的仿生聚合物表面均未能较好保留箬叶的动态润湿性能。实验结果表明,通过电铸-注射法构筑仿箬叶表面的微纳复合结构、在粗糙表面上修饰低表面能物质的双重途径可用于实现仿生疏水表面高效低成本的制备。

社会认知语用学(SCA)是近几年发展起来并有较大影响力的语用学理论。本文注意到在理论的启蒙、发展、成熟阶段及相关重要概念和议题的阐释与探讨中都大量地运用了“情境化话语”(SBUs),通过梳理研究发现:SBUs这种特殊的程式性话语不但能很好解析SCA理论中的合作-自我中心、凸显-关联、意图-注意、前语境-现实情境语境等核心概念,也能较好阐释英语作为国际通用语(ELF)和交叉文化的语用现象,揭示了SBUs在SCA理论建构中的重要作用。本研究有助于更好地理解SCA的理论内涵,也有益于拓展程式性话语的研究视野。
