行之有效的办法

• ( 5 ) the definitions , characteristics and all kinds of building algorithms of the voronoi diagram and the delaunay triangle are introduced . their applications in sdm are explored . that the voronoi diagram is an effective method to partition the influence regions between spatial objects and phenomena is put forward , and that the principle of building voronoi diagram is identical to the forming central place is proved
  ( 5 )系统研究了voronoi图和delaunay三角网的定义、性质及各种建立算法，并对它们在空间数据挖掘中的应用进行了探索性研究：提出voronoi图是界定空间目标(现象)的空间影响范围的一种行之有效的办法；从理论上论证了voronoi图的形成与城市中心地的形成是一致的，提出delaunay三角网是建立城镇网络体系的最佳模型；研究了利用voronoi图进行公共设施选址优化的算法及实现。
• Based on the above study , we draw the conclusion that the participatory instruction is an effective way to reform the traditional " spool - feeding way of teaching " it is also an effective means to quicken the steps of popularizing the compulsory education in the poor regions , it helps to promote the development and growth of student , enhances the teaching quality . and the action research enrich the teachers " professional knowledge and improve their practical ability . it is an ideal way to help to combine the teaching theory with the teaching practice
  通过研究得出了以下结论：参与式教学是改革传统的“注入式”教学的一个行之有效的办法；参与式教学是加快贫困地区普及义务教育步伐的有效途径之一；参与式教学促进了学生的成长和发展，提高了教学质量；行动研究丰富了教师的专业知识、学科知识，提高了教师的实践水平；行动研究是促使教育理论和教育实践相结合的理想途径。
