摘　　要：采用介质阻挡放电产生的常压冷等离子体对杨木单板进行改性处理，研究处理功率、处理速率和处理次数对杨木单板胶合特性的影响。结果表明：常压冷等离子体处理能显著改善杨木单板的胶合特性；经不同条件常压冷等离子体处理后，杨木胶合板的胶合强度提高幅度为10％～40％。较优的处理条件为：处理功率4．5kW，处理速率14m／min，处理次数为1次。The improvement bondability of poplar veneers by atmospheric pressure dielectric barrier discharge （DBD） treatment was investigated in this paper. The effect of processing power, treatment rate and treatment times on the bond- ing strength of plywood were evaluated. The results showed that the treatment could improve the veneer bonding strength remarkably. The improved rate of bonding strength ranged 10% -40%. Optimized processing conditions were as fol- lows：processing power 4.5 kW, treatment rate 14 m/min and the treatment times 1.
