摘要：In this paper it is proved that the chromatic index of every simple planar graph G with Δ=5 and without 6-cycles equaled to 5,i.e,such planar graphs are class 1.%运用Discharge方法以及临界图的一些重要性质,证明了每个最大度为5且不含六圈的简单平面图的边色数等于5,即这样的平面图是第一类的.
摘要：当前大学生心理健康课程体系存在着指导思想＂问题＂化、课程体系不完整、教学方式陈旧等问题,从而削弱了心理健康教育课程的作用。积极心理学视野下的大学生心理健康课程体系,将塑造积极人格作为教学目的,使用体验式教学方式,构建必修课加选修课的课程体系,并将学生的主观体验作为检验课程效果的依据。%There are following problems in college mental health curriculum.Guiding ideology is question model,the curriculum system is incomplete and teaching mode is obsolete.All these weaken mental health curriculum＇s position.The college mental health curriculum
摘要：Education includes teaching and learning,referring to teachers and students,and those two main parts are included in design of class teaching harmoniously.The key to foreign language teaching is interaction and the key to teaching interaction is the desig%教学包含了教和学两个过程,涉及教师和学生两个主体,而这两个主体和两个过程又和谐统一于课堂教学设计之中。外语教学的关键在于互动,而互动教学成功的关键又在于教学设计。互动教学设计体现了行为主义、认知主义和建构主义的教学设计观。外语互动教学的策略包括四个要点：注重以人为本、注重多媒体教学、注重启发式教学和注重模块教学。
摘要：It is an inexorable trend of the development to introduce the MCAI（Multimedia Computer Aided Instruction） into the professionally basal courses of mathematic,which have a higher theoretical and Abstract level.In the teaching of Mathematical Analysis which%将多媒体计算机辅助教学（MCAI）引入理论性强、抽象程度较高的数学专业基础课程是其发展的必然趋势.在传统的数学分析专业课程教学中融入这种新型的教学模式,还需要一个渐近和完善的过程.文章从揭示数学分析课程传统教学模式的弊端出发,结合教学实例有力地指出了MCAI引入数学分析课程的优势,讨论了MCAI环境下数学分析教学的体会与反思.
