Using d'Alembert equation as the approximation of Einstein's equation, a solution is given in this paper to the time‐dependent gravitational equation of the Earth in consideration of the Earth's features, which describes the characteristics of pulsation of the Earth and the structures of spherical layers of its interior, thus providing a theoretical basis for establishing the idea of mantle pulsation.
