| 中文摘要: |
| 颗粒材料是一种常见的复杂多体物质，其形态各不相同，颗粒之间通过相互作用使其表现出十分复杂的流体或固体特性。因此结合理论、实验及模拟的方法对颗粒材料进行研究，可以进一步发现颗粒的物理规律并对其进行表征，同时也有助于学者对颗粒材料的特性形成更加系统的认识。本文对颗粒材料在不同物质状态下表现出的不同流态特性与多尺度特点进行简要介绍，同时回顾了颗粒材料流-固特性的研究现状与2种状态下的实验研究方法，概括了相关测量方法的优缺点。 |
| 英文摘要: |
| Granular material is a kind of common complex multi-body material. It shows complex fluid or solid characteristics with different internal particle morphology, which makes it difficult for scholars to form a systematic cognition of its physical laws. Therefore, it is of great significance to characterize its laws through theoretical, experimental, and simulation methods. Based on the above discussion, different flow characteristics, multi-scale characteristics, and some experimental methods of granular materials in different material states were introduced. Combined with the measurement objectives of particles in different states, the common measurement methods of particle flow and solid particle system were compared and analyzed. |
