标题： Field Theory Approach In Kinetic Reaction: Role Of Random Sources And Sinks

摘要： 在通过Doi型主方程的二次量子化得到的场论模型框架下，我们研究了随机源和汇对主方程描述中的反应动力学的影响。 我们表明随机源和汇显著影响模型的渐近行为，并通过标度分析对其进行了描述，确定了两个普适类。 我们将结果与同一过程的Langevin方程描述进行了比较。 显示英文摘要

摘要： In the framework of a field theoretic model obtained by second quantization of Doi-type master equation, we investigate the effects of random sources and sinks on the reaction kinetics in the master-equation description. We show that random sources and sinks significantly affect the asymptotic behavior of the model and identify two universality classes when describing them using scaling analysis. We compare the results with the Langevin-equation description of the same process.
