潜在产出计算方法评析

本文在总结分析国内外潜在产出的计算方法的基础上,指出国外官方组织普遍认同以经济理论为依据的生产函数法计算潜在产出,我国则普遍通过统计方法分解得出潜在产出。二者在计算潜在产出时均存在一定的缺陷,我国采用的统计分解方法有主观性和偏差性较大的缺点,应加以改进。     

The linguistic construction of expert identity in professor–student discussions of science

This study examines how participation in a verbal exchange during an inquiry-based classroom activity allows three college students and their science instructor to use linguistic signs (choices of words, grammatical structures, discursive structures, prosody and poetic discourse) to construct authority and expertise. Our work explores linguistic and interactional processes of identification (the dynamic construction and transaction of expert identity) and examines how discursive strategies adopted by the professor at different moments of the verbal exchange influence the students’ subsequent discursive practices and perceptions of authority. We adopt a dialogic, socio-constructivist perspective on identity, viewing personal identities as being partially constructed via interactional positioning. Our findings reveal that the attainment of expertise involves two different types of language-mediated processes: the transmission of a professional vision or intension and the emergence of a perception of agency among students. The former is centered on referential-denotative meanings of speech (elicitation of standard account and operational definition) while the latter requires effective use of pragmatic–performative functions of speech (non-evaluative and more than minimal recipient practices). Consideration is given to the need for science instructors to be able to utilize pragmatic functions of language strategically to encourage students to position themselves within the identity of science expertise.     

Experimental Study of Structure Shock Vibration in Soil Caused by Explosion of Conventional Weapons

When hitting underground structures directly or exploding in rock-soil media near underground structures, the conventional weapons with large charge weight will make underground structures be subjected to strong shock vibration and cause personal casualty and damage of precision electronic equipments. The shock vibration has become one of the cardinal killing means of weapons. However, the existing methods of predicting structure shock vibration are limited evidently. In this paper the coupling coefficient of acceleration in clayey soil is obtained firstly. Subsequently based on repeated experiments of chemical explosion, after dimension analysis and by using method of multivariate stepwise regression, the calculation formulae of shock vibration acceleration for the underground structure are obtained finally. The formulae consider top and side explosion respectively, taking into account the effects of penetration depth, charge weight, distance to explosion center, rock-soil media, size of structure and buried depth. They are easy to use with high practicability and degree of confidence, and can provide credible evidence for prediction of shock vibration and vibration isolating design of underground structure.

基于计算分析的法律语体修辞特征研究

本选择《中华人民共和国国籍法》为分析本,通过“解剖麻雀”的方式,以计算分析和科学方法,总结归纳出法律语体的修辞特征及所要遵循的修辞基本原则。不仅与此前的语体修辞研究的“印象式”的非科学研究模式划清了界线,也为中国修辞学和汉语语体研究的科学化奠下了一块基石。

语言符号二重性的辩证关系

语言符号的任意性和象似性特征一直以来是语言学家争论的话题,直至今日还未能统一。其实语言符号的任意性和象似性的关系是辩证的,既相互对立,又相互补充,二者有机统一于语言的各个层面和范畴中。     

湖州市旅游景点标示英语问题分析及对策

英语社会用语由于语言和文化差异,如果使用不当将会失去语用功能,带来交际上的困难甚至障碍。通过对浙江省湖州市一些旅游景点标示英语中出现的问题,在分析原因的基础上提出相应对策,旨在净化标示英语,使其真正成为对外宣传的“窗口”。     

声符字假借义中无文献用例的形声字声符示源考——以《说文·人部》形声字为参照系

汉字在历史发展中增衍繁多的主要是形声字,同从一个声符的字就有许多。因此,字族、声符示源和语源义等内涵是研究形声字最基本的概念。本文拟对《说文·人部》形声字中散见于训诂专书和其它典籍中的同声符字所构成的同族材料加以甄选,进而对《说文·人部》中声符字假借义无文献用例的形声字声符的示源情况,做了较为细致地考证。     

论公示语文本规范化及其交际翻译原则

探讨了现代公示语的文本规范化问题,及其文本属性和应用功能,并以交际翻译原则为理论依托,阐释了公示语英译问题诸方面,认为翻译公示语应首先追问原文规范化程度如何,只有将其与翻译策略研究同时并举,才有利于公示语双语化实现其原本交际功能和意图。
