摘　　要：近年来研究发现,颗粒物质堵塞(Jamming)和非晶相变(Glass-transition)这两个看似毫不相干的体系之间有着密切关联:颗粒物质的堵塞与非晶相变、颗粒堆积与非晶结构之间有着惊人的相似性,对颗粒物质堵塞过程的研究被认为是微观非晶转变的宏观化研究。本文概述了颗粒物质堵塞行为的基本特征和颗粒堆积结构等问题的重要研究进展,阐述了颗粒物质堵塞临界行为与非晶相变的内在联系和相互借鉴的科学意义。Recently, researches have revealed that the granular jamming and glass-transition of amorphous matter, which seems to be out of the picture, may be intimately related to each other due to the strong analogies between these two systems. The progresses on the characteristics of granular jamming and the descriptions of amorphous structure, and the connectivity between the granular jamming and glass-transition are presented and shown, and the potential scientific interests are introduced in this paper.
