摘要：

We find a one-to-one connection between a variable-coefficient (3+1)-dimensional coupled partially nonlocal nonlinear Schrodinger equation and the constant-coefficient one, and get the analytical combined MA breather solution via the Darboux transformation based on this connection. From this analytical result, two types of combined MA breathers built from second-order Peregrine solution (PS) structures and PS triplet structures are constructed when the ratio of the growth rate parameters related to the modulation frequency is fixed as 1 : 2. The excitations to the original shape, summit and rump of PS structures in combined MA breathers will sequentially happen by selecting suitable parameters to compare the values between the maximum of the accumulated time and every summit locations of PS structures.
