摘　　要：以拉伸强度(TS)、断裂伸长率(E)、透光率(T)、溶解度(S)、水蒸气透过性(WVP)和氧气透过性(OP)等为品质指标,研究超声波功率和处理时间对蜂胶/纳米SiO_2复合膜品质的影响。结果表明,超声波处理能显著改善复合膜的性能。在试验范围,当超声波功率200 W,处理时间15 min时,膜的性能最佳,TS为13.00 MPa,E为3.99%,T为89.00%,S为33.58%,WVP为3.92 g/cm·s·Pa,OP为1.13 cm3/(m2·24 h·0.1 MPa)。Effect of ultrasonic power and treatment time on characteristics of nano-propois film including tensile strength （TS）, elongation （E）, transmittance （T）, solubility （S）, water vapor permeability （WVP） and oxygen permeability （OP） were investigated. The results show that ultrasonic treatment significantly improved the quality indexes of nano-propois film. Treatment with 200 W ultrasonic power for 15 min obtained, within the experimental range, the best quality film with TS as 13.00 MPa, E as 3.99%, T as 89.00%, S as 33.58%, WVP as 3.92 g/cm.s.Pa and OP as 1.13 cm^3/（m^2·24 h·0.1 MPa）.
