摘　　要：本文利用非线性动力学和流体力学方法研究闪烁偶极子流的混沌和混合机理,并提出用于度量混合程度的质点散布均匀度ξ的概念;利用多个非定常扰动可极大地促进混合。Using the methods of nonlinear dynamics and fluid mechanics, the chaos and mixing mechanism of blinking dipole flow is studied. It is found that the concept of particle distribution evenness ξ can be used to measure the degree of mixing, and using multiple unsteady disturbances greatly can enhance the mixing process.
