It has been the hotspot to reconstruct the education course based on the research-based learning in the course reform in many countries in recent years. The new course standard of China insists that the teaching is the interactive process that teachers and students communicate and develop together. In the teaching, the relationship between imparting knowledge and cultivating ability, and students' independence and self-determination should be emphasized, and teachers should lead students to doubt, survey, and search, and learn in the practice, and the learning should be the active and individual process under teachers' instruction. The exploring learning is just based on cultivating students' innovational spirit and practice ability. The research-based learning is introduced in the teaching of the modern physics experiment course, and this article mainly explores and attempts the concrete implementation and case design. Keywords:Research-based learning, Modern physics experiment, Teaching qualityIn recent years, to adapt the social development of China and the development of higher education, the expansion of university enrollment has cultivate more excellent talents for the society, which has expanded the scale of higher education, and enhance the overall national quality. But the problems which could not be neglected include that the common decrease of teaching quality, college student quality, basic knowledge, and learning, so it is the key to enhance the teaching quality and develop the teaching reform for the higher education of China and every college teacher, which could cultivate students' world view, strengthen students' ability of analyzing and solving problem, and cultivate students' exploring spirit and innovational consciousness. Combining with the practice of the modern physics experiment teaching, the actuality and problems in the modern physics experiment teaching are analyzed in this article, and many methods such as taking students as the main body, taking teachers as the main principle to enhance the teaching quality of modern physics experiment, and using the exploring learning to reform the modern physics experiment teaching are proposed. The basic concepts of the quality innovation and the research-based leaning are introduced, and the discussion of the research-based learning includes the research-based course theory (teacher teaching mode) and the research-based learning, which mean two directions. From the research-based course theory, the influence of the research-based physics experiment on the cultivation of college students' innovational quality will be discussed in this article. At present, the research-based course theory is widely used, and this article wants to provide a clearer concept and consecution of the quality innovation and the research-based learning to instruct the practice of the teaching of innovational education. At the same time, college students should learn more knowledge about this aspect, and prepare for establishing the innovational consciousness and im...
For the students who have just entered colleges, learning university physics would be a challenge. This paper discusses how to make students who have just finished senior high school physics won't feel difficult in learning university physics and how to guide and cultivate the students' interest in the study of physics so to stimulate the students' initiative to explore physics. The paper also attaches importance to the combination of high school physics and conducting teaching reform in college physical courses providing an effective way to solve the above question. This paper discusses the necessity of teaching reform in college physics teaching and the use of material and methods based on consideration of joining senior high school physics, attempting to find a breaking through the traditional single direction teaching mode, which can cultivate talents to analyze and solve problems with innovative quality.
The frequency spectrum of the permeability of the single-walled carbon nanotubes (SWCNT)-paraffin complex
is studied in 2-18GHz, which is very important for the absorption performance of materials. The microwave
absorption materials are required by strong absorption performance, wide frequency band, thin thickness, and
good environmental stability. Traditional microwave absorption materials could not well fulfill above
requirements. By the measurement and acquisition of the permeability paramet of SWCNT-paraffin complex in
2-18GHz and the Origin software under different conditions, the influence of the concentration and frequency of
the complex on the permeability of the carbon nanotubes is analyzed in this article
To increase the complex permeability and widen the frequency band of carbon nanotubes (CNTs) are the most essential ways for promoting the microwave-absorbing property of microwave-absorbing coatings on multi-wall CNTs. Therefore, we have investigated the relations between the microwave-absorbing behavior and the complex permeability of CNTs, analyzed the electromagnetic parameters of CNTs/paraffin composites of different concentrations under different frequencies, and figured out the external conditions to obtain the optimum wave-absorbing behavior, which is particularly helpful for the further development of new material.
Super capacitor is a kind of new energy-storage component developed in recent years, with many advantages such as large energy-storage capacity, light quality, pollution free, multiple charging and discharging. Starting from the principle, development, and application of capacitor, the electrode materials including activated carbon fiber, carbon nano tube (CNT), ordered mesoporous carbon, and graphene used for the super capacitor are introduced in this article.
