摘要: The evolution of morphological instability in solidifying succinonitrile has been investigated with high-resolution videomicroscopy. Quantitative analysis the early development demonstrated critical role noise, and indicates significant disagreement predictions Mullins-Sekerka theory. ratio tip radius rho/sup */ steady-state dendrites to length scale lambda/sub max/ initial was found be approximately 0.5, reasonable agreement a recent theoretical prediction Barbieri, Hong, Langer.
