摘      要：The effective one-body method provides a framework to apply the black hole perturbation theory to the binary system where two masses can be *** study the gravitational-wave equation in the background of the effective one-body system for the spinless binary,which is in general available with the spherically symmetric background as *** obtain the gauge conditions for the decoupled wave equation,and also give the solutions to the gauge conditions in terms of the metric perturbation for a special case,which extends the result by Jing et al.(***.65,260411(2022)).Finally we obtain the gravitational-wave equation which is the generalization of the Teukolsky equation.
