英文摘要: We discuss the possible solution of "coincidence" problem in the modified holographic dark energy (MHDE) model with an interacting term Q = 3 gamma rho(m). Theoretically, the phase-space analytical results of the automatic system of the equation of state (Los) parameter omega(d) and its evolution w(d)' show a scaling solution F-M appears in the interacting case which hints a possibility of alleviating the "coincidence" problem. On the observational side, the results from the combined data Supernova Legacy Survey (SALS) + Cosmic Microwave Background (CMB)/Baryon Acoustic Oscillations (BAO) + H-0 slightly favor a positive interaction it which meets the existing and unstable requirements of the scaling solution.
