A novel simplified method is presented to design FIR filter with controllable center frequency. The properties of transfer curves for all-phase filters are illustrated under 3 windowing conditions. By combining single-window all-phase filter design steps and double phase-shift combination, a series of design formulas for point-pass filter, notch filter, band-pass filter and band-stop filter are derived, thus the design computation complexity is greatly reduced. Experiments prove that the center frequency of all the filters can be accurately specified at arbitrary position by adjusting frequency parameters m and λ. 相似文献

作为一种跨文化交际行为,翻译的理解和表达都依赖于对语境的正确理解。关联理论中的最佳关联这一概念从认知的角度为翻译研究提供了一个新的视角。在具体的翻译活动中,译者如何求得最佳关联,正确理解原文本并生成最佳译文是建立在对相关语境的准确把握这一基础之上的。从关联理论的认知角度来研究翻译过程中译者如何实现最佳语境关联对翻译实践具有很重要的指导意义。 相似文献

Increased activity of multiple stakeholders (e.g. agents and owners) have created new challenges for some coaches working in professional sports clubs. The purpose of this project was to draw attention to the normative or accepted practices inherent in sport work, some of the day-to-day realities of some coaches working in this context, and to understand how coaches’ perceptions of other stakeholders come to bear on their individual circumstances, career expectations/objectives and professional agency. Data were generated from semi-structured interviews with seven professional basketball coaches who worked in top-level European clubs. The analysis reveals the coach’s relationships between some owners and agents differed with respect to exercising professional agency, and, coach’s decisions and actions were tied to their professional ideals as well as understandings of what they need to undertake their work effectively and negotiation and/or adjustment strategies. Occasionally coach’s work practices could be viewed as antithetical to employment security, however, the presence of insecurity was at times embraced and used strategically to affect workers’ career decisions. Amid contemporary regional geo-political shifts, this work aids examinations of global sport settings, structures and issues that may contour sporting professionals’ lives. 相似文献

This paper discusses a survey, carried out by the authors, of 211 employees’ employed in public and private manufacturing organizations in North India to determine if emotional stability acts as a mediator between self-disclosure and social adjustment. Capitalization theory has been used as theoretical framework to examine the proposed relationships. Results indicate that high self-disclosure has positive association with social adjustment. Results also suggest that emotional stability partially mediates self-disclosure and social adjustment relationship. Implications for future research include further examination through additional mediators and other dimensions of self-disclosure from capitalization theory in understudied non-U.S. cultures like India. 相似文献

ABSTRACTThis study explored 150 EFL teachers’ perceptions of critical cultural awareness (CCA) considering their teaching context, academic degree, and professional development programs. The participants all completed the CCA questionnaire, fifteen of whom also sat a semi-structured qualitative interview. Our findings showed, a) EFL teachers’ perceptions of CCA located at a medium level, b) the PhD participants showed significantly higher engagement in CCA than their BA and MA counterparts, c) private language institute teachers reported higher levels of CCA than their state-run school counterparts and d) local professional development programs did not emphasize culture teaching in general and CCA in particular. 相似文献

利用层状双氢氧化物(LDH)合成原理,提出了即时合成LDH处理染料废水的新方法,并对其可行性进行了实验研究。其基本原理是,在废水处理中,由于Mg2+、Al3+水解共沉淀形成LDH,阴离子染料优先进入LDH结构层间平衡结构电荷,从而使阴离子染料以LDH沉淀的形式被去除。这一原理已通过模拟废水实验和沉淀物结构分析证实。文章探讨了反应时间、pH值、Mg/Al比值、温度对染料去除率的影响。结果表明,在常温下,最佳pH值为9.0,反应时间为2小时,Mg/Al比值为3:1,对活性艳蓝染料的去除率效果十分显著。 相似文献

本文从尼尔·波兹曼"娱乐至死"这一命题产生的美国语境入手,考查它在美国语境和中国语境下各自的阐释力,进而寻求对这一命题更深刻的认识。本文认为,对这一命题的讨论和研究要有较好的问题意识,不能泛化和无条件的加以运用。 相似文献
