摘　　要：主要从超稳分子筛(USY)的制备与改性技术两个方面介绍了USY分子筛的改性研究进展。对USY分子筛进行改性,调变其结构和表面酸性,可以达到改善其催化性能的目的。常用的改性方法有:负载阳离子及氧化物、酸处理、再脱铝(生成DUSY)等;并对以后USY分子筛的改性进行了展望。The research progress on modification of USY zeolites consisting of preparation and modification technology was introduced in this article. Modified on the USY zeolites,modulated its structure and the surface of acidity, in order to improve its performance. The usual methods of modification are used：loading cation and oxide,acid treatment,and then redealumination （generated DUSY） and so on. The development prospects for modification of USY zeolites were put out.
