我们介绍了一种实验方法来结晶合奏的非布朗球限制在狭窄的容器。该方法是基于程序振动和冷却过程（退火）。从颗粒状气体开始，系统缓慢地松弛成固体有序结构：根据毛细管的尺寸获得体心四轴和面心立方单晶。干燥和润滑珠行为不同，表明颗粒之间的粘附系数是重要的结晶动力学。
We introduce an experimental method to crystallize ensembles of non-Brownian spheres confined in narrow containers. The method is based on programed vibrations and a cooling procedure (annealing). Starting with a granular gas, the system slowly relaxes into a solid ordered structure: Body-centered-tetragonal and face-centered-cubic single crystals are obtained depending on the dimensions of the capillaries. Dry and lubricated beads behave differently, indicating that a sticking coefficient between the particles is important in the dynamics of the crystallization.
