所谓“多次作用”问题,是指在某些物理过程中,系统内物体问存在着多次不同的相互作用过程的问题,求解这类问题,往往需要使用归纳法先总结出规律或先推导出一个通式,然后在此基础上求出问题的解,下面,举几例并作剖析,旨在说明数学归纳法在“多次作用”问题中如何应用。 The so-called “multiple effects” problem means that in some physical processes, there are many different interaction processes among the objects in the system. To solve such problems, it is often necessary to use induction to summarize the laws first or First derive a general formula, and then solve the problem on the basis of the solution, the following, to give a few examples and analysis, aimed at illustrating how the mathematical induction method in the “multiple effect” problem.
