摘要
In this paper, the Jacobi elliptic function expansion method provides an effective approach to obtain the exact periodic wave solutions of two-component Bose-Einstein condensates. Exact combined bright-bright and dark-dark soliton wave solutions can be achieved in their limit conditions. We also obtain the different formation regions of combined solitons. Our results show that the intraspecies （interspecies） interaction strengths clearly affect the formation of dar^dark, bright-bright and dark-bright soliton solutions in different regions.
