摘要: 为进一步增大盐水振荡产生的电势差,并使盐水振荡可逆,该文将液膜振荡与盐水振荡耦合,组成一个耦合的振荡器.实验结果发现:(1)由于两振荡器耦合形成共振,所以此耦合振荡器的振幅明显增大; (2)耦合后的化学振荡器变为可逆振荡器.耦合振荡机理如下:扩散过程中形成的缔合物存于油相,难溶于水,通电后缔合物发生解离,因此造成反扩散,形成可逆振荡,且可逆程度及逆反应产生的电势差(即振幅)大大提高,扩展了盐水振荡在二次电池开发方面的应用.

Abstract: In this thesis, the coupling interactions of the salt-water oscillator and liquid membrane oscillator have been investigated in order to increase the potentials and create a reversible chemical oscillator. The results indicate that:(1) the increase of the potentials may be attributed to the resonance of the coupling; (2) a reversible oscillator was formed by the coupling of the salt-water oscillator and liquid membrane oscillator. And a possible mechanism for the coupling and reversible oscillation was presented: a coordination compound was produced in the diffusion process, which dissolves in the oil phase but not in the water phase. Furthermore, when electrified, the coordination compound dissociates and the reversible oscillation takes place. So the application of the salt-water oscillator, especially in the second battery, may be extended.
