A new set of phase variables is proposed and justified to develop automatically by computer the solar terms in Lunar Theory. The dependence of the perturbation function on the mass ratio MoonEarth Moon is completely elucidated. A recursive procedure is proposed to develop that function so as to keep explicit all its dAlembert characteristics. The perturbation series obtained by computer is compared with Delaunays development.
