解决物理学问题要有好的方法,才能做到准确简捷方便快速.针对某些动态变化的问题,如果按常规的方法计算和证明,不仅花费很长时间,步骤复杂,计算繁琐,而且有时还不易理出个头绪,如果用极端法解决则简捷而准确.一、极端法的概念极端法,又称极端假设法、极值法,就是通过对研究对象或变化过程的分析,提出一种或多种夸大或缩小的极端假设,并针对极端假设进行分析、比较,从而确定极端的变化结果,最终做出判断和选择的方法.极端法使用于条件不足(可能)无法求
To solve the physics problem has a good method, in order to be accurate and simple and convenient. For some dynamic problems, if calculated and proved by conventional methods, not only takes a long time, the steps are complicated, the calculation is cumbersome, and sometimes Not easy to find out a clue, if the extreme law to solve the simple and accurate. A, the concept of extreme law Extremes, also known as extreme hypotheses, extremes, through the analysis of the research object or process of change, or a A variety of exaggerated or reduced extremum assumptions, and analysis of extreme hypotheses, compared to determine the extreme changes in the results, and ultimately make judgments and choices.
