摘要：

The expected chirp mass distribution of observed events for future gravitational wave detectors is extensively investigated in the presence of an exotic fluid component with an arbitrary equation of state, -1 less than or equal to omega (x) = p(x)/rho (x) < 0, i.e., the so-called dark energy component. The results for a at model dominated by dark energy are compared to those for the standard at model dominated by cold dark matter. It is found that for a at universe the chirp mass distribution shows a sensitive dependence on <omega>(x), which may provide an independent and robust constraint on the cosmic equation of state.
