ترجمة الملخص

The lunar theory is an important problem in astronomy at the whole world, that all civilizations interest in the lunar motion. The understanding of this motion is became a part of its culture, that use this understanding in calculation of time .Euler, Lagrange, Chapron and other researchers studied this problem. This study uses the perturbative methods. A strange resonance is noted, in secular problem, that doesn’t depend on parameters. In this memory, we study some points of the lunar theory. We start with an exposition on the determination of the position of an aster, using its elliptical coordinates. Then, we study the tow body problem, explaining some important points in it , and the variables describing the phase space. We study also the classical lunar theory, described by the classical and spherical variables. We study the secular problem with the classical coordinates, and note the celebrate resonance. We explain this resonance with the spherical variables. Then, with this variables, we give the conditions on its existence. This conditions are verified. Using the geometry, we demonstrate, that this resonance is result of a harmony in the perturbative 108 function. This harmony gives an infinite of relations, one of them is equivalent to this non-parametric resonance. The residue of the relations don't be used to understanding the dynamical signification of this relations, and its usage to explain the motion of moon. These are an open problem; we wish to solve it.
