The macroscopic mechanical property and the stability of granular mechanics system are determined by packing structure. Cells play a fundamental role in granular statistical mechanics and thus cells were utilized in this paper to research the packing structure of disk particles and gear particles in a two-dimensional cubic container. The probability distribution of cell order satisfie... https://www.ealisboa.com/great-deal-Pentair-Union-Collar-2-U11-200PS-super-offer/
