我们考虑了一类在定态下呈现凝聚跃迁的零程过程，其临界单点分布的衰减速度快于幂定律。我们在完全图上对系统在临界和凝聚阶段的粗化动力学进行了分析研究。与临界单点分布按幂规律衰减的零程过程不同，在目前的情况下，有限时间修正的作用对于理解定标方法是必不可少的。
We consider a class of zero-range processes exhibiting a condensation transition in the stationary state, with a critical single-site distribution decaying faster than a power law. We present the analytical study of the coarsening dynamics of the system on the complete graph, both at criticality and in the condensed phase. In contrast with the class of zero-range processes with critical single-site distribution decaying as a power law, in the present case the role of finite-time corrections is essential for the understanding of the approach to scaling.
