摘要：

Noise-induced synchronization vas investigated in a large number of chemical oscillators coupled to each other in the photosensitive Belousov-Zhabotinsky (BZ) reaction system. The oscillator consisted of an ionic head for absorbing catalyst ions and the reaction occurred only on it. We studied two different synchronization systems: a two-oscillator system for investigating the fundamental features of noise synchronization dynamics and a multiple-oscillator system in which the oscillators are coupled in a lattice arrangement for studying group synchronization by noise. The synchronization rate depended on the distance between chemical oscillators. 13 increasing the noise intensity. the number of synchronized oscillators increased and showed a maximum at a certain optimum noise intensity. That is stochastic synchronization in BZ reaction vas clearly observed in the spatially discrete distribution system.
