二维约束轨道振动粒子的动力学
Kinetics of 2D-constrained orbitally-shaken particles
摘要:
我们提出了一个实验研究的轨道振动宏观粒子的动力学局限于一个二维有界域。折扣的强制作用的外部周期性的驱动,粒子显示平移速度和扩散率符合一个受限的随机游走模型。因此,这样的实验系统可以代表一个合适的宏观模拟研究方面的分子动力学和自组装。
英文摘要:
We present an experimental study of the kinetics of orbitally-shaken macroscopic particles confined to a two-dimensional bounded domain. Discounting the forcing action of the external periodic actuation, the particles show translational velocities and diffusivity consistent with a confined random walk model. Such experimental system may therefore represent a suitable macroscopic analog to investigate aspects of molecular dynamics and self-assembly.
