Oscillation reactions such as Belousov-Zhabotinsky (B-Z) reactions proceed periodically through the synergestics among substances, which resemble temporal orders and/or spatial pattern formations in nature. These oscillation reactions and pattern formation proceed through non-linear dynamics, whose science is in potential progress recently.Oscillatory phenomena of B-Z reaction can be seen by dramatic color change in beaker and in petri-dish.These color changes in temporal and/or in spatial oscillations are fantastic and attract young students. This will give them interested in science.In this project, we aim to developed the system and teaching aids for science education through the oscillation reaction and pattern formation. In 1992 and 1993, the basic mechanism of Belousov-Zhabotinsky and salt-water oscillation were mainly studied. Non-linear dynamic of these oscillatory phenomena were traced by electrochemical and spectrochemical methods. Various audio-visual aids were made.Chemical behaviors of B-Z reaction were studied by changing reaction conditions such as, initial composition of reactants, photo-illumination and types of reaction vessel.In 1994, the mathematical structure of B-Z reaction dynamics was clarified by the Oregonator, the basic model for B-Z reaction, and a text for junior course of the university students was made.The photo-modulation of B-Z reaction were studied and applied to a image processing. The educational approach of salt-water oscillator and various non-linear dynamics such as synchronization and attraction of oscillation.Various audio-visual teaching aids were made using oscillation reaction and pattern formation.

振荡反应如Belousov-Zhabotinsky（B-Z）反应通过物质之间的协同作用周期性地进行，这类似于自然界中的时间顺序和/或空间模式形成。这些振荡反应和图案的形成是通过非线性动力学进行的，这门学科最近正处于潜在的发展阶段，B-Z反应的振荡现象可以通过烧杯和培养皿中的剧烈颜色变化来观察，这些时间和/或空间振荡的颜色变化是奇妙的，吸引着年轻的学生。本计画的目的是透过振荡反应与模式形成，开发科学教育的系统与教具。1992年和1993年重点研究了别洛乌索夫-扎博廷斯基和盐水振荡的基本机制。这些振荡现象的非线性动力学跟踪电化学和光谱化学方法。1994年，B-Z反应的基本模型Oregonator阐明了B-Z反应动力学的数学结构，研究了B-Z反应的光调制，并将其应用于图像处理。介绍了盐水振荡器的教学方法和振荡的同步、吸引等各种非线性动力学，并利用振荡反应和图形形成制作了各种视听教具。
