物理现象千差万别。表里都相异的问题是大量的,然而,完全不同的两种物理理象,却在某个方面具有相似之处,这种情况也不是绝无仅有的。对两种相异的物理现象,由于它们有相似的物理规律,因此,将这两种物理现象进行类比,并且可以用其中一种已知的物理现象的规律去解决另一物理现象中的问题,我们把这一分析物理问题的方法称之为“相异相似法”。 Physical phenomena vary widely. There are a lot of questions that are different in the table. However, two completely different physical theories have similarities in one aspect. This situation is not unique. For two different physical phenomena, because they have similar physical laws, the two physical phenomena are analogized, and one of the known physical phenomena can be used to solve problems in another physical phenomenon. We call this method of analyzing physical problems the “differential similarity method.”
