以多节棍的摆动为例讨论用连续模型处理离散系统的条件,并利用系统之间的相似性,顺便给出一维原子链的相关结论.
The condition of treating with discrete system by using continuous model is investigated from swing of multi-section sticks.By the way,the interrelated conclusion about a linear monatomic chain is given by the use of comparability between systems.
