摘　　要：研究了稀土、过渡元素复合氧化物加少量贵金属汽车尾气三效催化剂的性能 ,包括蜂窝状第一载体粉碎后制备样品的性能。This paper discusses the behaviours of rare earth and transition element complex oxide catalysts with a small amount of noble metal for controlling the automotive exhaust. The behaviours include the behaviour of the prepared sample after the first alveolate carrier is shattered, the three way activity of a whole piece of alveolate catalyst which is shattered measured in the laboratory and the purification of a reactor made of a piece of alveolate catalyst installed in the Changan Aotus cars.
