摘要翻译：
研究了一个粒子在有限距离上相互作用的自催化反应体系。我们研究了模型的离散颗粒特性对反应速率、猝灭现象和前沿传播等性质的影响，重点讨论了与连续情况的差异。我们引入了一个依赖于相互作用半径和粒子密度的重整化反应速率，并将其与系统的宏观可观测量（如前部速度和前部厚度）联系起来。

英文摘要：
An autocatalytic reacting system with particles interacting at a finite distance is studied. We investigate the effects of the discrete-particle character of the model on properties like reaction rate, quenching phenomenon and front propagation, focusing on differences with respect to the continuous case. We introduce a renormalized reaction rate depending both on the interaction radius and the particle density, and we relate it to macroscopic observables (e.g., front speed and front thickness) of the system.
