草图反映了解题人对题意的理解,画草图的过程就是对试题的“翻译”过程,草图本身就是将题中的文字信息转化为形象的图形信息的过程.画好草图不但有助于理解题意、形成直观的视觉载体,而且对物理过程的分析、解题思路的确定和良好思维品质的形成等都具有重要的意义.一、画好草图便于展示物理过程,使问题的分析连贯、有序分清物理过程,是解决问题的基础.只有物理过程清晰明了,才能使问题的分析系统、全面、具体、准确.例1(2000年高考) 在原子核物理中,研究核子
The sketch reflects the understanding of the problem and the understanding of the problem. The process of drawing a sketch is the process of “translating” the test. The sketch itself is the process of converting the text information in the question into the image information of the image. Drawing a sketch not only helps Understanding the meaning of the questions and forming an intuitive visual carrier, and the analysis of the physical process, the determination of problem-solving ideas, and the formation of good thinking qualities are of great significance. First, draw a sketch to facilitate the display of the physical process and make the analysis of the problem consistent. The orderly separation of physical processes is the basis for solving problems. Only when the physical processes are clear and clear can the problem analysis be systematic, comprehensive, concrete, and accurate.
