Belousov-Zhabotinsky（BZ）行波的波长是限制BZ自激振荡凝胶马达规模的关键因素。为了实现波长的控制，有必要评估波长对物种浓度和温度的依赖性。本文研究了反应参数对BZ脉冲波波长的影响。减小脉冲波波长的最有效方法是增加有机物质的浓度和/或温度。降低溴酸盐、氢离子或金属催化剂的浓度也会降低脉冲波的波长。这一工作提供了一种方便、直接的亚毫米波BZ波产生方法，可用于BZ波驱动的小尺度凝胶马达的设计，也为研究自振荡凝胶的其他涌现行为提供了理论依据。
The wavelength of Belousov−Zhabotinsky (BZ) traveling waves is the key factor that limits the scale of BZ self-oscillating gel motors. To achieve control of the wavelength, it is necessary to evaluate the wavelength dependence on species concentrations and temperature. In this work, the effect of reaction parameters on the wavelength of BZ pulse waves was studied. The most effective way to reduce the wavelength of pulse waves is to increase the concentration of organic species and/or the temperature. Decreasing the concentration of bromate, hydrogen ion, or metal catalyst also reduces the wavelength of pulse waves. This work provides a convenient and direct method to produce sub- millimeter BZ waves, which could be applied to designing BZ wave-driven small- scale gel motors as well as providing insight into other emergent behaviors of self- oscillating gels.
