临界状态是指物理现象从一种状态变化成另一种状态的中间过程,这时存在着一个过渡的转折点。临界问题的分析对象正是临界状态。与临界状态相关的物理条件则称为临界条件。临界条件是解决临界问题的突破点,在物理解题中起着举足轻重的作用,解答临界问题的关键是找准临界条件。临界条件一般是隐藏着的,需要同学们仔细分析题目才能找出来。但它也有一定
The critical state refers to the intermediate process of the physical phenomenon changing from one state to another state. At this moment, there is a transitional turning point. The critical problem analysis is the critical state. The critical physical conditions associated with the critical state are called critical conditions. Critical condition is a breakthrough point to solve the critical problem, plays a decisive role in physical problem solving, the key to answer the critical problem is to find critical conditions. Critical conditions are generally hidden, students need careful analysis of the problem can be found. But it also has some
