高考物理压轴题都是能力考察的综合分析题,而这些综合分析题往往涉及到临界问题的分析,对于这样的试题确定临界点(状态)和临界条件是整个试题解答的关键,而正确分析临界点(状态)和临界条件是解题的着力点。对考生而言,如何找到并正确分析临界点(状态)和临界条件是很伤脑筋的。本文就这一问题作如下的讨论。 The college entrance examination physical pressure axis questions are comprehensive analysis questions of the ability to examine, and these comprehensive analysis questions often involve the analysis of the critical question, for this kind of questions to determine the critical point (state) and the critical condition is the key to the whole question answer, and the correct analysis of the critical Points (states) and critical conditions are the focus of problem solving. For candidates, how to find and correctly analyze critical points (states) and critical conditions is very nerve-racking. This article discusses this issue as follows.
