摘要: Une theorie de fonctionnelle densite, fondee sur l'approximation densite aplanie, est presentee afin d'etudier les transitions phase systemes spherocylindres durs degres liberte entierement-translationnels et orientationnels. On trouve a la fois une transition nematique-isotrope nematique-smectique A dans large gamme quotients longueur/largeur (L/D). Les resultats cette concordent avec des simulations par ordinateur limite d'Onsager L/D→∞ retrouvee. Des commentaires l'application aux d'ellipsoides dures sont proposes
