摘要翻译:
我们讨论了在底物上自催化反应$a+b\到2a$的一个模型,其中反应物对空间进行紧致探索,即在光谱维数$\tilde{d}$为$<2$的晶格上。对于有限体系,根据两种不同的体系,即高浓度和低浓度的反应物,反应到最终标度的总时间$\tau$。在平均场近似下,讨论了Tau$与底物体积和反应物浓度的函数依赖关系。讨论了可能的应用。

英文摘要:
We discuss a model for the autocatalytic reaction $A+B\to 2A$ on substrates where the reactants perform a compact exploration of the space, i.e., on lattices whose spectral dimension $\tilde{d}$ is $< 2$. For finite systems, the total time $\tau$ for the reaction to end scales according to two different regimes, for high and low concentrations of reactants. The functional dependence of $\tau$ on the volume of the substrate and the concentration of reactants is discussed within a mean-field approximation. Possible applications are discussed.
