The response of a nonlinear state to a variable forcing periodic in space is studied in an extended dynamical system consisting of a liquid crystal layer driven to convection. Both the statics and the dynamics of the entrainment and the locking effects are analyzed. The dynamics of the evolution are controlled by topological singularities that allow a diffusion of the phase. The mechanisms involved are related to the role of the defects in systems undergoing spontaneous symmetry breakings.
在一个由被驱动至对流的液晶层构成的扩展动力系统中，研究了非线性状态对在空间上呈周期性变化的强迫作用的响应。对夹带和锁定效应的静态和动态特性均进行了分析。演化的动力学过程由允许相位扩散的拓扑奇点控制。所涉及的机制与缺陷在经历自发对称性破缺的系统中的作用有关。
