对大学物理课程中“e指数规律”的探讨

DISCUSSION ON“E-EXPONENTIAL LAW”IN COLLEGE PHYSICS

本文对大学物理课程中的一类物理过程,即物理量满足其改变率与其本身成正比的物理过程进行了分析与探讨,发现这些物理过程虽然具有不同的运动形式,但是相应的物理量随时间、距离等的变化均满足“e指数规律”。满足“e指数规律”的物理过程在大学物理中广泛存在,因此对这一类物理过程作总结可提高学生对相关物理知识综合理解。

In this paper,we analyze and discuss a special kind of physical processes in college physics,that is,the physical processes whose change rate is proportional to itself.Although these physical processes have different forms of motion,the corresponding changes of physical quantities with time,distance and other physical quantities satisfy the“e-exponential law”.Physical processes that satisfy the“e exponential law”exist widely in college physics.Therefore,summarizing these physical processes can improve students'comprehensive understanding of relevant physical knowledge.
