选频网络的品质因数分析     

李四信  吕小秀 《赣南师范学院学报》1996,(3):43-48

在很多电学书本中,品质因数的概念都不太明确,容易引起误解。品质因数在选频网络中,标志着选频的质量,是个很重要的参数。本文分析了一些常见电路的品质因数及其计算方法,并得出了实际电感、电容并联网络品质因数的精确结果。  相似文献   

阿Q与陈奂生之比较   总被引：1，自引：0，他引：1  

漆福刚 《陕西理工学院学报(社会科学版)》2005,23(3):48-53

鲁迅的《阿Q正传》、高晓声的《陈奂生上城》都因作品中成功的人物形象赢得了高度的评价和热烈的赞誉,在中国现当代文学史上拥有很重要的地位。阿Q、陈奂生这两个艺术形象虽然都是农民,但是他们生活的时代不同,就又使他们各有特点了,成为两个不同历史时代的缩影。阿Q是典型的旧式不觉悟农民形象,性格中带有极深的奴性,“精神胜利法”是其性格的主要特征;陈奂生是走在改革开放的大道上,物质生活得到了改善,但精神生活却极度贫乏,憨直、朴实,又带有点“阿Q气”的新时期典型的农民形象。他们性格中落后的东西都因袭了历史重负的缘故,但阿Q性格中的“精神胜利法”与陈奂生性格中的“阿Q气”又是异中有同,同中有异。  相似文献   

阿Q的"精神胜利法"与陈奂生的"阿Q气"     

漆福刚 《湖北广播电视大学学报》2005,22(1):60-63

鲁迅的《阿Q正传》、高晓声的《陈奂生上城》在中国现当代文学史上都有很重要的地位。阿Q、陈奂生这两个艺术形象虽然都是农民,但是他们生活的时代不同,就又使他们各有特点了。成为两个不同历史时代的缩影。阿Q是典型的旧式不觉悟农民形象,性格中带有极深的奴性,“精神胜利法”是其性格的主要特征;陈奂生是走在改革开放的大道上,物质生活得到了改善。但精神生活却极度贫乏,憨直、朴实,又带有点“阿Q气”的新时期典型的农民形象。他们性格中落后的东西都因袭了历史重负的缘故,但阿Q性格中的“精神胜利法”与陈奂生性格中的“阿Q气”又是异中有同,同中有异。  相似文献

Post-colonial science education: the challenge of negotiating researcher positioning     

《International Journal of Research & Method in Education》2013,36(3):242-255

In this paper, I describe a methodology that I employed, and resultant methods that I designed, to facilitate a Critical Discourse Analysis exploring perspectives on Western modern science as a school subject discipline in a given Caribbean context. Using specific themes from post-colonial theory, I sought to engage with some of the viewpoints presented by key stakeholders in secondary science education in the research setting. This paper reports on the methodological framework for the research study, illustrating some of the philosophical challenges encountered during the development of the research methods. Specifically, I discuss the tensions associated with the pursuit of researcher legitimacy, the use of ‘scientific’ methods of inquiry in a work that seeks to be decolonizing, and the challenge of stimulating conversation about a topic for which participants might not possess readily formulated opinions. My response to these challenges resulted in methods that utilized a unique adaptation of Stephenson's Q methodology. Although these tensions are far from being fully resolved, the approach outlined helps contribute to our understanding of the complexities of negotiation that can occur when conducting research of this nature.  相似文献

An Integrative Analysis of Reputation and Relational Quality: A Study of University-Student Relationships   总被引：1，自引：1，他引：0  

Sung-Un Yang  Dennis F. Kinsey 《Journal of Marketing for HIGHER EDUCATION》2013,23(2):145-170

The purpose of this research is to explore the link between reputation and relational quality in the context of student-university relationships, based on a perceptual analysis of the participants' subjective views (i.e., factor analysis with Q methodology). To this end, the researchers selected a private university located in the Northeast region of the United States as the research setting, with students of the university serving as research participants. The researchers proposed three research questions regarding the link between student-university relational quality and university reputation. The findings of this research indicate that the concepts of relational quality and reputation can be “variantly” intertwined on the basis of individual stakeholders' subjective views of their experience, interactions, and information, rather than intertwined in a linear way.  相似文献   

The technological system of production and innovation: The case of photovoltaic technology in China     

Mahmood H. Shubbak 《Research Policy》2019,48(4):993-1015

This research paper studies the Chinese technological system of production and innovation in the field of photovoltaics (PV). It contributes to a better understanding of the emergence and development of the system by utilizing three levels of analysis: the institutional framework of the system, the market dynamics of production and deployment, and the composition of innovation-related activities. The analysis demonstrates the interrelated roles of transnational factors, local government policies, and research and development (R&D) activities undertaken by the main actors in shaping the system dynamics. Tracking the relative position of China in the global PV manufacturing, installation and technological development, the analysis shows a gap between the growth of China’s market share and its modest share of transnational patent applications. This suggests a puzzle, which the paper attempts to answer by inspecting the individual companies in the system against four aspects. First, the dynamic development of their size and performance. Second, the nature of their international involvement through foreign direct investment and mergers and acquisition deals. Third, their technological specialization within the PV value chain over time. Fourth, the spatial scope of their patenting protection endeavours. The analysis recognises four periods of system development driven jointly by market dynamics and government plans. Behind the continuous growth of the system, there were different driving and moderating factors in each period.  相似文献   

Do electric vehicle incentives matter? Evidence from the 50 U.S. states     

Sherilyn Wee  Makena Coffman  Sumner La Croix 《Research Policy》2018,47(9):1601-1610

We estimate the effectiveness of policy incentives for adoption of electric vehicles (EVs) in the 50 U.S. states. We employ a rich dataset of semi-annual state-level new EV vehicle registrations by make and model from 2010 to 2015 and state-level policy instruments that could affect new EV model registrations. We construct two measures of policy, one which aggregates policy instruments that can be assigned a value and a second that aggregates those without explicit values. Using a within model difference-in-difference estimator with high-dimensional fixed effects, we find that a $1000 increase in the value of a state’s model-specific EV policies increases registrations of that model within the state by 5–11%.  相似文献   

从“人”出发，永无穷尽——重读《阿Q正传》     

李玉 《娄底师专学报》2009,(5):82-85

作为“精神界之战士”的鲁迅,以“立人”为中心,倾其毕生精力对人的精神世界进行了深邃而独到的探讨,其锋芒直逼人的灵魂。他在对“人”的探索和创作实践中,吸纳前人的美学思想精髓,形成自己独特的美学思想体系。然后又把这二者结合起来指导创作活动,使其作品特别是《阿Q正传》等,体现出复杂的美学蕴涵,凝聚着深邃广博的人学信息,让后人无法穷尽。  相似文献
