摘要
本文以数学摆为例,说明不满足线性微分方程的物理规律不能应用叠加原理.通过晶格的微振动论述了对于同一线性系统用牛顿力学方法和分析力学方法处理,得到的结论是一致的.
In this papar,itis illustrated that the principle of superpositioncannot be used to study the physical law of unsatisfied differentialequation,by taking the mathematical penduhm for example.Andthrough the lattice vibration,it is expounded that the similarconclusion can be drawn if the the same linear system is delt with byboth Newton's mechanical method and analytic mechanical method.
