In the frame of the vortex self - organization dynamics the question of the interaction of binary vortices is investigated by using a numerical model and the differences and homogeneities of binary vortices interaction under the two types of conditions of weak enviromental fields and vortices swarm ambient flow are analyzed 摘要在涡旋自组织动力学的框架内，数值研究了涡群中双涡相互作用的问题，对比了弱环境流与涡群环境流两类条件下双涡作用的异同。
