我们使用高速摄影来观察两个紧密间隔的平行板之间的冰的树枝状冻结。测量枝晶的传播速度，我们调查是否有一个约束引起的热影响的速度超出了由一个单一的表面。隔热塑料板和中等导热玻璃板可单独或组合使用，温度在−10.6至−4.8 °C之间，间距在17至135 μm之间。在玻璃表面上的传播没有检测到约束的效果，但在绝缘板之间看到传播速度可能减慢。还研究了枝晶生长的模式，从弯曲到直枝晶的变化与从玻璃到塑料基板的切换密切相关。冰被冻结在平行板之间，以寻找对枝晶传播速度的限制效应。在20 μm以下的限制和-5 °C以下的温度下，没有发现这种效应的确凿证据。我们注意到一个强烈的变化时，从导电的绝缘基板的枝晶图案。
We use high-speed photography to observe the dendritic freezing of ice between two closely spaced parallel plates. Measuring the propagation speeds of dendrites, we investigate whether there is a confinement-induced thermal influence upon the speed beyond that provided by a single surface. Plates of thermally insulating plastic and moderately thermally conductive glass are used alone and in combination, at temperatures between −10.6 and −4.8 °C, with separations between 17 and 135 μm wide. No effect of confinement was detected for propagation on glass surfaces, but a possible slowing of propagation speed was seen between insulating plates. The pattern of dendritic growth was also studied, with a change from curving to straight dendrites being strongly associated with a switch from a glass to a plastic substrate. Ice is frozen between parallel plates to look for a confinement effect upon the speed of dendrite propagation. No firm evidence of such an effect is found with confinements down to 20 μm and temperatures up to −5 °C. We note a strong change in dendrite pattern when moving from a conductive to an insulating substrate.
