教师信息化素养是教师整体素养的有机组成部分,但当前高校教师存在观念陈旧、信息意识淡薄、信息技术使用的创新能力不高等问题,制约着高校教育现代化的发展。要提高高校教师的信息化素养,教师必须更新观念,增强其对信息的敏感度和创新能力。同时高校还要建立一套行之有效的管理制度,做好教师的培训工作。  相似文献   

Some Problems in Nonlinear Dynamic Instability and Bifurcation Theory for Engineering Structures     

彭妙娟  程玉民 《上海大学学报(英文版)》2005,9(1):29-34

In civil engineering, the nonlinear dynamic instability of structures occurs at a bifurcation point or a limit point. The instability at a bifurcation point can be analyzed with the theory of nonlinear dynamics, and that at a limit point can be discussed with the theory of elastoplasticity. In this paper, the nonlinear dynamic instability of structures was treated with mathematical and mechanical theories. The research methods for the problems of structural nonlinear dynamic stability were discussed first, and then the criterion of stability or instability of structures, the method to obtain the bifurcation point and the limit point, and the formulae of the directions of the branch solutions at a bifurcation point were elucidated. These methods can be applied to the problems of nonlinear dynamic instability of structures such as reticulated shells, space grid structures, and so on.  相似文献
