摘要：
We modify the usual directional solidification equations for the case of large pulling velocities (rapid solidification). Using these equations we describe a numerical method to analyze the stability for numerically obtained cellular structures. We find cells which are oscillatory unstable which will lead to the observation of banded regions in the experiment. The width of these bands are estimated and found to agree roughly with the experimentally observed ones.
