Therefore, attention is paid to the collisional stresses in the study of rapid granular flows.
因此，碰撞应力是快速颗粒流研究的主要内容。
Particle collisions are the main mechanism of the momentum transfer, the energy transfer and the energy dissipation for rapid granular flows.
颗粒碰撞是快速颗粒流的动量传递，能量传递及耗散的主要机制。
Individual fingers are replaced by a single mass of granular material that, when pressed onto a target object, flows around it and conforms to its shape.
用大量微小的颗粒状材料取代了手指，当它要抓住一个东西的时候，颗粒材料就被吹起来以符合物件的形状。
