数值实验表明,当驱动强度大于某一阈值,并且适当选择驱动频率和驱动相位时,阻尼型交流驱动的Toda晶格可以支持孤子的稳定传输。通过改变损耗因子和驱动参数,对这一现象进行了深入的研究。特别地,找到了与不同孤子速度对应的驱动参数的阈值。
It is demonstrated using numerical experiments that the damped AC-driven Toda lattice can support stable propagation of solitons, if the drive strength is above a certain threshold value, and the drive frequency and phase are properly chosen. This phenomenon is thoroughly studied by varying the dissipation factor and the drive parameters. In particular the threshold values of the drive parameter corresponding to different soliton velocities are found.
