Résumé

Pour témoigner l'efficacité de la nouvelle methode d'analyse spectrale employant l'approximation des moindres carrés, on a analysé le mouvement du pôle terrestre utilisant des observations effectuées depuis Janvier 1951 jusqu'à Octobre 1966. Les résultats s'accordent avec les valeurs déjà établies des périodes et des amplitudes de la constituante annuelle at chandleriene. De plus, ces valeurs paraissent confirmer l'existence d'une periode d'à peu près 24 années qui fut revélée par Markowitz.
