实验表明，有界单胞中向错的交叉和相互交换依赖于指向矢的表面取向和向错的相对强度。相反强度的线在边界板之间切换销接端，并且如果曲面方向相切，则彼此独立地消失。相反，倾斜的表面取向保持线的稳定性。
It is shown experimentally that crossing and intercommutation of disclinations in a bounded nematic cell depend on surface orientation of the director and the relative strength of disclinations. Lines of opposite strength switch the pinned ends between the bounding plates and vanish independently of each other if the surface orientation is tangential. In contrast, tilted surface orientation preserves the stability of lines.
