摘要：

A study of the dynamics of the cellular solid-liquid interface in directional solidification of a dilute CBr4 alloy has allowed us to observe a number of secondary instabilities (travelling states, optical modes, anomalous cells, etc.) some of which were well known and traditionally attributed to the effect of crystalline anisotropy. However, most of these instabilities are also observed in a hydrodynamic analog of directional solidification, directional viscous fingering (M. RABAUD, S. MICHALLAND and Y. COUDER, Phys. Rev. Lett. 64 (1990) 184). This analogy enables us to discuss the interplay of crystalline anisotropy and of the dynamics generic to one-dimensional systems in directional solidification.
