摘　　要：在50 mm的微机化多功能精馏实验装置中,以乙醇-正丙醇为体系对4种高比表面积(分别为900,1100,1700,2500 m2/m3)的金属丝网波纹填料的流体力学和传质性能进行了研究。结果表明,2500Y型填料的阻力很高而传质效率较低。其他3种填料的传质效率随比表面积增大而提高,但900Y和1100Y型填料的综合性能较好。The hydrodynamic and mass transfer characteristics of 4 kinds of Y-type gauze corrugated packing with high specific surface area （900, 1100, 1700, 2500 m^2/m^3 respectively） were systematically studied in a multifunctional distillation column. The results show that the 2500Y packing has very high resistance and poor mass-transfer efficiency due to its extremely narrow flow channel. The mass-transfer efficiency increases with the specific area for the other 3 kinds of packing. However, the 900Y and ll00Y packing have better performance in general
