摘　　要：较全面地评述了国内外在沸石分子筛吸附和扩散领域的研究现状;在此基础上,提出了该研究领域共存的若干重要科学问题;最后,以烷烃异构体在silicalite-1及二氧化碳和甲烷在DDR型沸石分子筛中的吸附和扩散为体系,展望了用于解决在该领域内共存的重要科学问题的实验和理论研究方法.发展基础理论和实验技术用于表征沸石分子筛,将极大地促进我国在沸石分子筛方面的深入研究.A comprehensive review was presented on the research status of the field of adsorption and diffusion in zeolites,several generic,bottleneck scientific problems in the conducted field were proposed.The adsorption and diffusion of alkane isomers in silicalite-1 and of CO2 and CH4 in the zeolite DDR were taken as an investigating system to anticipate experimental and theoretic approaches to solve the proposed generic,bottleneck scientific problems.It was suggested that development on new theories and experimental techniques for the characterization of zeolites would significantly enhance the research level of China in the conducted field and improve its international recognition.
