我们知道,物理学是研究物质世界运动中普遍、最基本运动形式的一门学科。因此“运动的观点”应贯穿于解题的始终,本文所讨论的所谓巧解,其实也就是“运动变化”思想在各个方面的若干反映,本文尝试着将辩证法思想潜移默化于物理解题中,如极限思维方法(即是一般问题的特殊情形),或辩证地赋值、量纲辅助分析法对进一步提高同学对单位的认识很有益处,或者巧妙实现问题的转化等等。下面举数例予以说明。
We know that physics is a discipline that studies the universal and basic form of movement in the physical world movement. Therefore, the “sports point of view” should be applied throughout the problem-solving process. The so-called “sportsmanship solution” discussed in this article is actually a reflection of the “movement change” idea in various aspects. This article attempts to subtle the dialectical thinking into the physical understanding problem. For example, the limit thinking method (that is, the special case of a general problem), or the dialectical assignment and dimension analysis method is helpful for further improving the students’ understanding of the unit, or ingeniously achieving the transformation of the problem. Here are a few examples to illustrate.
