在今年全国初中物理知识竞赛试题中,用作图线的方法探索物理问题是试题的明显特点,而画示意图解竞赛题则不失为解题的良策.图在解题过程中起着极其重要的作用,图形象直观能启发思维和开导思路.在数学、物理等学科中探索问题和解决问题往往都离不开图.审题时画示意图常常是化难为易的好方法,不但形象直观,而且培养思维能力.画好示意图有助于建立物理图景、认清物理现象,利用图的数学 In this year’s national junior high school physics quiz contest, the use of graphs as a method to explore physical issues is an obvious feature of the questions, and drawing a schematic solution to a contest is a good strategy for solving problems. Graph plays an extremely important role in the process of solving problems. , Intuition of figure image can inspire thinking and enlighten ideas. In mathematics, physics and other disciplines to explore the problem and solve problems are often inseparable from the drawing. Drawing sketches are often a good way to solve difficult problems, not only the image is intuitive, but also to cultivate thinking Ability to draw diagrams helps to establish a physical picture, understand physical phenomena, and use graphs in mathematics
