物理过程的阶段性分析

Analysis of physics process' steps

以 2 0 0 0年一道高考试题的物理过程分析为例 ,将一个复杂的物理过程按发生的先后分成几个阶段进行分析 ,使物理问题简化 ,体现了分析物理过程的重要性。

With one physics question from the 2000 years' College Entrance Examination as the example, the author makes physics questions simpler and shows the importance of the analysis of physics process through analysing a complicated physics question by several steps according to process steps.
