摘要：
A jet-type instability was observed in two dimensions for the isothermal dynamics of a liquid strip surrounded by its solid phase. This instability was concluded to be due to both diffusion and capillary effects driven by the strong curvature of the solid-liquid interface. The dependence of the emission frequency and the droplets radius on the growth velocity was also studied.
