比较是确定研究对象之间差异点和共同点的思维过程和方法.各种物理现象和过程都可以通过比较来确定其差异点和共同点,为进一步抽象概括做好准备工作.比较是理论思维的一种重要方法,也是科学地认识自然的重要方法.比较是以已有知识为基础,为进一步认识事物的内在的本质属性和规律而必须做的第一步工作.比较方法能启发和开拓人们的思维,能给人们提供解决问题的线索,那么在物理问题解决中有哪些应用呢?笔者就比较法在 Comparison is to determine the differences between the research objects and common points of thought process and method.A variety of physical phenomena and processes can be compared to determine the differences and common ground for further abstraction to prepare for the work.Comparison of theoretical thinking Is also an important method of scientific understanding of nature.Comparison is based on existing knowledge, in order to further understand the intrinsic nature of things and the law must do the first step.Comparison method can inspire and develop People’s thinking, to provide people with clues to solve the problem, then what are the applications in the physical problem solving? I compare the law
