本文预言了在周期场作用下,弯晶沟道的混沌行为。分析了系统的全局分叉性质和出现Smale马蹄的参数条件,指出系统通向混沌的过程就是粒子的退道过程,而相的沟道效应和沟道辐射都将表现出内在的随机性,为定量解释沟道效应和沟道辐射的某些特征提供了一种可能的理论分析。The chaotic behaviours of bend crystal channel under the action of periodic field was predicted. The properties of global bifurcation in the system and the condition for occurrence of Smale horseshoes were analyzed, and we showed that the process of approaching chaotic state is the dechanneling process of a particle, and the channeling effect and channeling radiation would exhibit intrinsic stochasticity. The results provided possible theoretical analysis for quantitative discription of channeling effect and channeling radiation.
