In the framework of the discrete self-trapped model and its generalizations, the dynamics of two nonlinear elements of different physical origin is considered. The influence on the dynamics of their own nonlinearity, various types of interaction nonlinearity and nonequivalence of subsystems is investigated. Exact solutions of dynamic equations are found and investigated. Particular attention is paid to the study of essentially nonlinear inhomogeneous states with different levels of excitation for identical subsystems as a discrete analogue for different solitons.

耦合非线性系统的动力学。二、离散自陷模型

在离散自陷模型及其推广的框架中，考虑了不同物理起源的两个非线性元素的动力学。研究了子系统自身的非线性、各种相互作用的非线性和非对等性对动力学的影响。找到并研究了动态方程的精确解。特别注意研究具有不同激发水平的相同子系统的基本非线性非均匀状态，作为不同孤子的离散模拟。
