在物理学发展史上,物理学家们对物理规律的研究特点是,一般先对一些物理问题进行定性分析,几乎不用任何计算就能够粗略地获得各量之间的关系,显示出该问题的物理景象,并产生一个能够得到预期结果的方案。而在定性分析中,经常采用的物理思想方法就是猜想。一、猜想需要以事实为依据猜想是人们根据一定的经验材料和已知事实,对未知事实或现象的原因及其规律所做的一种有一定 In the history of physics development, physicists’ research on the laws of physics is that qualitative analysis of some physical problems is generally conducted first, and the relationship between the quantities can be roughly obtained without any calculation, showing that the physics of the problem Scene, and produce a program that will produce the desired result. In qualitative analysis, often used method of physical thinking is to guess. First, the conjecture needs to be based on the facts Guess is that people based on certain empirical material and known facts, the reasons for unknown facts or phenomena and their laws have a certain
