1Research on the Teaching Mode of Entrepreneurial Project Management General Courses显示文摘Under the background of 'the Belt and Road' and 'Internet +', innovation and Entrepreneurial education in colleges and universities has been pushed to the focus of education. The opening of the course 3.0 'Entrepreneurial Project Management' in General Studies course of Wuhan University is an innovative education mode under the requirements of the background of the times. The development of network information technology in the new era has brought about the subversion and reform of teaching mode. This paper first analyzes the problems and present situation of the teaching of Entrepreneurial project management, introduces the characteristics of the teaching mode, and makes effective research and exploration on the three teaching modes of Entrepreneurial project management, in order to provide reference for the curriculum teaching reform and to promote the teaching effect of innovation and Entrepreneurial courses in colleges and universities.Lai Yifei Zhao Xiaoqian Zhang Wan 2019教育研究前沿(中英文版)2019,9,2:4
2Dielectric Properties of Polytetrafluoroethylene/CaCu_3Ti_4O_(12) Composites显示文摘Polymer-based composite was investigated by embedding calcium copper titanate(CaCu_3Ti_4O_(12); CCTO) fillers into polytetrafluoroethylene(PTFE) matrix. The dielectric performances of the composite were investigated within the frequency range from 100 Hz to 1 MHz. It is indicated that dielectric permittivity(ε) and dielectric loss(tanδ) increase gradually as the filler content increases. Dielectric permittivity for the composite with 50 vol% CCTO filler loading is 33.5, approximately 16 times higher than that of pure PTFE(ε = 2.1) at 100 Hz. As the frequency increases, the dielectric loss decreases rapidly and reaches stability, and then remains low when the frequency rises to 1 MHz. The values for dielectric permittivity and dielectric loss in the microwave frequency(8-13 GHz) are lower than that in low frequency of 10 kHz for the composites because of different polarization modes. Several theoretical models were implemented to compare the experimental results with the theoretical calculations and the modified Lichtenecker equation was found to fit the best.梁飞 ZHAO Yifei CHEN Xizi WAN Qianxing Lü Wenzhong 2019Journal of Wuhan University of Technology(Materials Science)2019,34,1:3

6Research on Teaching Mode of 'Entrepreneurial Project Management' Course based on Flipped Classroom显示文摘Under the background of the era of “mass entrepreneurship and innovation”, innovation and entrepreneurship education in colleges and universities has been promoted to the focus of educational work. The establishment of self-improvement and entrepreneurship class in Wuhan University is an innovative education mode under the requirement of 'Double Creation' education. The development of network information technology in the new era has given rise to the subversion and reform of teaching models. The appearance of flipped classrooms has broken the barrier of traditional education and provides a new train of thought for innovation and entrepreneurship teaching model reform in colleges and universities. This paper takes the self-improvement entrepreneurship class of Wuhan University as an example, introduces the flipped classroom into the course of 'Entrepreneurial Project Management', and analyzes the application process of the flipped classroom in the course teaching from three aspects: before class, during class and after class, in order to provide a reference for the curriculum teaching reform and promote the teaching effect of innovation and entrepreneurship courses in colleges and universities.Lai Yifei Zhang Wan 2019管理科学与研究(中英文版)2019,8,1:1
