定性分析类选择题在近年的各地物理高考试卷中不断涌现,解答此类问题要求我们要有较高的推理判断能力。下面举例说明,希望能够对同学们有所帮助。一、假设分析法如果由于某个物理量的变化,会引起多个物理量的发生变化,如果同时考虑这几个物理量的变化,可能常常会 Qualitative analysis of multiple choice questions in recent years around the physical entrance examination papers continue to emerge, to answer such questions require that we have a higher ability to reasoning. Here’s an example, hoping to help students. First, the assumption that if the analysis as a result of a change in the amount of physical, will cause changes in the number of physical changes, if you consider these changes in the physical variables may often
