在垂直于其 c 轴生长的冰晶与其熔体之间的界面处观察到增强的光散射。通过光子相关光谱在一定范围的晶体生长速率和施加的温度梯度下研究该现象。将结果与使用 c 轴晶体的类似实验进行比较。监测从平衡状态过渡到生长稳态状态期间界面的运动，并提出描述该过渡时期的兼容理论。
Enhanced light scattering is observed atthe interface between an ice crystal growing perpendicular to its c axis and its melt. The phenomena is investigated by photon correlation spectroscopy over a range of crystal growth rates and imposed temperature gradients. Results are compared to similar experiments in which c-axis crystals were used. The motion of the interface during the transition from an equilibrium to a growing, steady-state condition is monitored and a compatible theory describing this transition period is presented.
