| 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。指出：弱环境流条件下双涡合并的过程，在涡群环境条件下不再存在；同时，涡群环境流的引进可使涡强度显著增强。

| Abstract: | 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.It is shown that under the enviromental condition of vortices group the merger process of binary vortices happened in the case of weak enviromental fields no longer occurrs;and meanwhile,the introduction of vortices swarm might lead to the intensification of vortices. |
