摘　　要：电偶极子是电介质理论和原子物理学的重要模型,探究两电偶极子间的相互作用对实际应用具有深远的意义.为了得出直角坐标系下两任意电偶极子间相互作用力的普遍表达形式,进行了相关计算.先通过电势叠加原理计算了两电偶极子间的相互作用能,然后根据相互作用能与相互作用力的关系,推导出了两电偶极子间相互作用力的普遍表达形式.针对一些特殊情况进行了分类讨论,得出了特殊情况下的相互作用能和相互作用力,并和相关文献进行了相互验证.所得结果为电偶极子的相关计算提供了借鉴作用.Dielectric dipole is an important model in dielectric theory and atomic physics.The research about Interaction of two dielectric dipoles is very important for practical application. Some calculation were carried out for getting universal expression about interaction force between two electric dipoles. First,interaction energy between two electric dipoles was concluded by superposition principle of electric potential. Then the universal expression about interaction force was concluded by the relationship between interaction energy and interaction force.The interaction energy and interaction force were discussed in some special cases,and the discussion was mutual verification with the relevant references.The result can be referenced in some similar cases.
