化学波是由于反馈步骤与扩散的相互作用而以恒定速度传播的浓度脉冲波。在一些化学、物理和生物系统的“活性介质”中观察到这种波和结构，例如，多相催化反应、燃烧或种群迁移。180年前，Luther 2首次演示了波在自催化化学系统中的传播。化学波的研究在过去的15年中取得了重大进展，其中Belousov-Zhabotinsky（BZ）反应及其改进的反应已被用于化学波的实验。丙二酸-溴酸盐-亚铁体系3”19是
Chemical waves are waves of concentration impulses travelling at constant velocity due to interaction of feedback steps with diffusion. Such waves and structures are observed in “active media" in several chemical, physical, and biological systems, eg, heterogeneous catalytic reactions, combustion or migration of populations. 1The first demonstration of wave propagation in autocatalytical chemical systems was performed by Luther2 80 years ago. Significant progress in the study of chemical waves has been achieved during thepast 15 years, in which the Belousov-Zhabotinsky (BZ) reaction and its modifications have been employed for such ex-periments. The malonic acid-bromate-ferroin system3" 19 was
