堵塞描述了颗粒（如颗粒或气泡）松散组合体中从流动或液体状态到固体或刚性状态的转变。相比之下，堵塞描述了颗粒物质通过瓶颈的流动停止。目前尚不清楚如何区分堵塞和堵塞，也不知道它们是不同的现象还是基本相同。我们研究了一个组件的磁盘移动通过一个随机的障碍物阵列，并确定从堵塞的过渡到干扰行为的磁盘密度的增加。堵塞转变具有吸收相变的特征，在临界发散瞬态时间之后，盘演变成非均相分离堵塞状态。与此相反，堵塞是一个快速的过程中，磁盘形成一个均匀的不动的包装，与刚性长度尺度，发散的堵塞密度接近。
Jamming describes a transition from a flowing or liquid state to a solid or rigid state in a loose assembly of particles such as grains or bubbles. In contrast, clogging describes the ceasing of the flow of particulate matter through a bottleneck. It is not clear how to distinguish jamming from clogging, nor is it known whether they are distinct phenomena or fundamentally the same. We examine an assembly of disks moving through a random obstacle array and identify a transition from clogging to jamming behavior as the disk density increases. The clogging transition has characteristics of an absorbing phase transition, with the disks evolving into a heterogeneous phase-separated clogged state after a critical diverging transient time. In contrast, jamming is a rapid process in which the disks form a homogeneous motionless packing, with a rigidity length scale that diverges as the jamming density is approached.
