我们给出了一种计算作用在向列点缺陷上的弹性力的一般方法：这些力是使缺陷运动的力，因此它们与缺陷动力学特别相关，这是最近引起人们极大兴趣的一个主题。这些力是由指向矢场中的缺陷引起的扭曲所调节的，例如，它们负责相反拓扑电荷的缺陷之间的吸引。
We present a general method to compute the elastic forces exerted on nematic point defects: these are the forces that set defects in motion, and so they are especially relevant to defect dynamics, a subject which is recently attracting much interest. These forces are mediated by the distortion introduced by defects in the director field; for example, they are responsible for the attraction between defects of opposite topological charge.
