中文摘要	A review is given of our previous work on the clustering, especially the oscillatory clustering for shaken fluidized granular matter in connected compartments, as examples for pattern formation and bifurcations in far fromequilibrium systems. Flux model is presented and discussed for mono-disperse and bi-disperse granular systems. Comparison of the flux model with simulation results is given. They show reasonably well agreements. Besides the homogeneous (HOM), segregation (SEG), and oscillatory (OSC) states, two new stationary states (d-OSC and s-HOM) in the bi-disperse granular system are predicted by our simulation. In our recent work these two new states are observed experimentally, and their flow diagrams are obtained based on the flux model, which shows qualitative agreement with the experimental results. Discussions of variations of the above system are also given, such as adding an asymmetric structure, changing the number of compartments from two to three, and adding more than two types of particles. This compartmentalized fluidized granular system turns out to be a good model system for studying nonlinear dynamics and pattern formation of far from equilibrium systems.
