Global attractor for a nonlinear plate equation with supported boundary conditions

AbstractIn this paper, we consider a two-dimensional nonlinear equation(∗)ρwtt+DΔ2w+εμwt−(N1+T2∫Ωwx2dxdy)wxx−(N2+T2∫Ωwy2dxdy)wyy=0 which arises from the model of the viscoelastic thin rectangular plate with four edges supported. By virtue of Galerkin method combined with the priori estimates, we prove the existence and uniqueness of the global solution under initial–boundary data for the above equation. Especially the existence of the bounded absorbing set in space E and the existence of the global attractor of system is also obtained

Teaching Practice about Flipped Classroom on Circuit Course

In view of the problems in circuit course, flipped classroom is introduced and new teaching mode is explored. Teaching design, teaching reform suggestion, teaching effects and results are presented. It is verified that this kind of teaching mode can enhance the enthusiasm, initiative and participation of the students, teaching efficiency is also improved. It is also a good way for comprehensive practice
