Examples
- Finally , the results are compared with periodic and random chains . then we studied acoustic wave propagation in 1d quasiperiodic and aperiodic systems by means of he transfer matrix . transmission rate , reflection rate , energy flow , logarithmic energy flow , energy density and lyapunov exponent are computed numerically , and compared with periodic and random system
其次研究了声波在几种一维准周期和非周期系统中的传播，通过转移矩阵的方法，数值地得到了系统的传播系数t _ n 、反射系数r _ n 、能流密度j _ n ，能量密度e _ n和lyapunov指数，给出了以上各量与传播长度n以及频率之间的关系，同时发现能流及能量密度都具有分形结构，并与周期和随机系统的结果作了比较。 - Firstly , acoustic waves propagation in id quasi - periodic system is studied by means of the transfer matrix method . the transmission rate , reflection rate , energy flow , logarithmic energy flow , energy density and lyapunov exponent are obtained numerically . we explain all these parameters " relations with frequency and the size of system , and compare these p arameters with those o f periodic system . we find that these parameters are fractal in this quasi - period system
通过转移矩阵的方法，数值地得到了系统的传播系数t _ n 、反射系数r _ n ，能流密度j _ n 、能量密度e _ n 、李雅谱诺大指数_ n ，给出了以上各量与系统大小n以及频率之间的关系，发现这些量存在着与周期系统不同的准周期性质，其能量会出现局域化现象，能流以及能量密度都具有分形结构，给出了相应的理论解释。
