我们调查积极有利的配置点向错在具有凸点几何形状的薄膜。凸块宽度Δ的逐渐扩大引起向错的稳定位置从凸块的顶部到边缘的突然移动。在阈值Δ t上观察到的位置偏移服从幂律函数：|Δ - Δth|表明了一类新的连续相变，它控制着弯曲薄膜中的缺陷结构。
We investigate energetically favorable configurations of point disclinations in nematic films having a bump geometry. Gradual expansion in the bump width Δ gives rise to a sudden shift in the stable position of the disclinations from the top to the skirt of the bump. The positional shift observed across a threshold Δthobeys a power law function of |Δ - Δth|, indicating a new class of continuous phase transition that governs the defect configuration in curved nematic films.
