Nous présentons une étude sous pression des anomalies qui apparaissent dans les mesures de résistivité à 145 K et 59 K dans le composé NbSe3. Ces anomalies sont supposées être dues à l'apparition d'ondes de densité de charge. Les températures de transition décroissent avec la pression avec la même pente dT/dp = 4 K/kbar. Nous avons aussi observé la suppression de ces deux anomalies par l'application d'un champ électrique que nous attribuons à un effet tunnel à travers des gap extrêmement petits introduits par les ondes de densité de charge.We report the effect of pressure on the two resistivity anomalies at 145 K and 59 K in NbSe3 and resulting from charge density wave formation.
