Some basic dynamic properties, such as symmetry, dissipation, continuous spectrum and chaotic behaviors of the butterfly attractor are studied. Furthermore, period-doubling bifurcations in a system with definite parameters has been investigated.展开更多

The existence domain of the peaked solitary waves are found. The analytic expressions of peaked solitary wave solutions are obtained. Our numerical simulation and qualitative results are identical.展开更多

Given that it was a particularly stimulating and informative weekend I wish to draw out and summarise some key themes I gained from the conference for the benefit of interested teachers who were unable to participate. The themes include insights into language teaching goals and possible cross-disciplinary directions across China. The article concludes with some suggestions for future conference papers. Having come from outside of China and currently practicing as an English teacher in China, and being one of only two conference participants teaching in China’s Southwest Yunnan province, I may be able to provide some broad and different insights that can be used as a basis for further discussion. In combining these conference themes, this paper calls for increased cross-disciplinary and cross-cultural dialogue in the context of English teaching research and practice in China.展开更多
