摘　　要：硫化学非线性反应体系是非线性化学的一个重要部分,在均相和反应扩散介质中均表现复杂自组织现象,尤其该类体系在前沿波作用、迷宫波及倍增分裂波研究和近几年斑图系统设计的突破起着关键作用。根据参与的物种数量将硫化学反应体系分为简单的两组分和三组分反应体系两大类。本文重点介绍了近三十年来这两类硫化学振荡器和反应-扩散斑图的研究进展,简述了该类反应体系在生物及其软物质领域的应用。最后,对硫化学振荡体系研究中存在的问题进行了探讨,并对今后的研究方向进行了展望。Sulfur-contained nonlinear reaction system is a significant branch of nonlinear chemistry, which can display complicated dynamics both in the homogeneous and reaction-diffusion medium. In particular, it also plays a critical role in the aspect of fronts interaction, labyrinthic pattern, self-replication pattern and systematical design of pattern formation in recent years. According to the number of oscillatory components, sulfur-contained oscillatory systems are mainly divided into two-component systems and three-component systems. The progress on sulfur-contained compound oscillators and pattern formation during the past three decades are introduced in the review. Furthermore, the potential application of the sulfur-contained oscillators and the involved reaction systems in biological field and responsive gel medium are systematically summarized. The difficulties existed in this active field are discussed in detail and the future directions are prospected.
