There exists a threshold-sensitive dynamical transition between uniform and periodic growth modes in the domain growth of ascorbic acid crystals from its aqueous supersaturated solution film. The crystal growth induces solution flow. Humidity controls the fluidity of the solution. The solution flow varies the film thickness. The threshold exists in the thickness of the solution film. If the thickness becomes lower than the threshold, the solution flow and the crystal growth almost stop.

抗坏血酸晶体在水过饱和溶液膜中的磁区生长过程中，均匀生长模式和周期生长模式之间存在阈值敏感的动态转变。晶体生长诱导溶液流动。湿度控制着溶液的流动性。溶液流量会改变膜厚。阈值存在于溶液膜的厚度中。如果厚度低于阈值，则溶液流动和晶体生长几乎停止。
