Reducing greenhouse gases (RHG) is going on actively in the international movement. In the field of architecture, RHG is an inevitable work. To establish a plan for RHG, firstly we need to reduce energy consumption. Greenhouse gas generated by energy consumption is the main cause of global warming. For this we should know that how much electricity consumption we use. The research targets of this study are commercial buildings with various businesses. Their electricity consumption was analyzed by business units rather than buildings. Each business was divided into 13 sectors according to industrial classification and electricity consumption was analyzed for each industry. For commercial buildings, the electricity consumption is done by the private sector and construction management is an autonomy system in private instead of an integrated management system. In this study, we classified and analyzed the electricity consumption characteristics according to collected data, analyzed the relationship between the electricity consumption with atmospheric temperature through SPSS, and developed an electricity prediction model.  相似文献   

焦循曲论之“谬悠”说     

裴雪莱 《孝感职业技术学院学报》2011,(4):70-74

焦循曲论充分肯定了戏剧创作中的虚构手法,并以＂谬悠＂称之。＂谬悠＂之说,形成于长期以来大量的艺术创作实践中,具有鲜明的民族特色和悠久的历史传统。焦循将＂谬悠＂说运用于历史剧点评,认为历史剧和史实之间存在相互印证的关系,剧作家的合理虚构甚至比史官记录更符合历史真实。此外,＂谬悠＂手法在塑造戏剧人物方面也发挥着至关重要的作用。＂谬悠＂之说对于戏剧艺术尤其是历史剧的创作构思、剧情结构和人物塑造具有重大意义。  相似文献   

Torsional effect of space structure in frequent earthquakes     

WANG Xiu-li  JIN En-ping 《重庆大学学报(英文版)》2011,10(2):84-92

Taking a concrete frame supporting space structure as the research object, we systematically studied its lateral-torsion coupling effect of reverse problems in consistent earthquake excitation. Firstly, based on its reverse forms and features, we put forward a mechanical analysis model (flexibility layer model) and a calculation method using the response spectrum method and the weighted average method, and verified their validity and feasibility using case analysis. The result shows that the translation displacement change trend of the space structure is basically the same whether reverse exists in the supporting structure or not, but the supporting structure torsion has an effect on the displacement with a relative increase of 10?.  相似文献   

Walking backwards into the future: Indigenous wisdom within design education     

Nan O’Sullivan 《Educational Philosophy and Theory》2019,51(4):424-433

This research parallels Tongan academic Hūfanga ‘Okusitino Māhina’s assertions in the 1994 Contemporary Pacific article Our Sea of Islands, that ‘People are thought to walk forward into the past and walk backward into the future, both taking place in the present, where the past and the future are constantly mediated in the ever-transforming present’ alongside those of Professor Terry Irwin and fellow Transition Designers in which they discuss the use of Indigenous Wisdom to enable designing for the Long Now as defined by Brand in his 1999 book The Clock for the Long Now: Time and Responsibility. In the 2015 Transition Design Monograph Irwin asserts that, ‘Transition Design draws on knowledge and wisdom from the past to conceive solutions in the present with future generations in mind’. This paper draws on the pre-industrial wisdom of indigenous knowledge, specifically that of the Pacific regions, Moana, who have lived and designed sustainably in-place for generations to illustrate the value it holds for the formulation of sustainable and sustaining futures.  相似文献

Students' reasoning about chemical bonding: The lacuna of repulsion     

Asnat R. Zohar  Sharona T. Levy 《科学教学研究杂志》2019,56(7):881-904

This article concerns a lacuna in chemistry students' reasoning about chemical bonding. Although chemistry students are familiar with the charges that make up the atom––both positive and negative––they refer only to the attraction between unlike charges. Specifically, they ignore the repulsion between the positive nuclei. We named this disregard of repulsion the lacuna of repulsion. Repulsion is a crucial component in the force-based explanation of chemical bonding, presenting the bond as a dynamic equilibrium between attraction and repulsion electrical forces. We noticed this lacuna incidentally while interviewing chemistry students for a bigger project aimed at supporting students in understanding the force-based explanation of chemical bonding. This article describes our systematic qualitative study of the lacuna of repulsion and its impact on mental models of 23 high school chemistry students. Our findings show that students use six mental models, most of them built upon each other. Beginning from a simple mental model that describes the chemical bond as electrons, continuing with the including attraction forces, and completing with repulsion and a dynamic view of the bond. Only when one considers both attraction and repulsion forces and understands the dynamic balance between them is it possible to build the force-based dynamic mental model of chemical bonding.  相似文献   

Investigating the relationship between pre-service physics teachers' professional knowledge,self-concept,and interest     

Stefan Sorge  Melanie M. Keller  Knut Neumann  Jens Möller 《科学教学研究杂志》2019,56(7):937-955

This study investigates the relationships between professional knowledge, self-concept, and interest of pre-service physics teachers. In order to support student learning and interest development alike, teachers need a profound professional knowledge and respective motivational orientations. Developing both professional knowledge and motivational orientations in teachers is therefore a key challenge of teacher education. Prior research has focused on the development of content knowledge (CK) and pedagogical content knowledge (PCK) within teacher education, but the role of motivational orientations such as self-concept and interest have mostly been neglected areas of study. As individuals develop domain-specific motivational orientations, they compare their achievement in an external frame to the achievement of their peers, and they compare their achievements in an internal frame across domains. The effects of these psychological processes on domain-specific motivational orientations are described by the generalized internal/external frame of reference model (GI/E model). We assessed the professional knowledge (CK and PCK) and motivational orientations (self-concept and interest) of N = 200 pre-service physics teachers from 12 teacher education institutes in Germany. To investigate the predictions of the GI/E model, we utilized structural equation modeling. In line with the GI/E model, the analysis revealed that pre-service teachers use social comparisons. Pre-service teachers with a higher CK/PCK also showed a higher CK/PCK self-concept. We also identified instances of internal comparisons as we found that a high level of CK corresponds with a lower PCK self-concept. While we could not identify the same effects from professional knowledge on interest, self-concept mediated the effects from professional knowledge on interest. The results suggest that interdependencies between professional knowledge and motivational orientation should be given more consideration in teacher education research and should also be addressed more explicitly in teacher education.  相似文献
