摘　　要：采用酸性染料对速生杨木单板染色,考察染液质量分数、染色时间和染色温度对单板色差值的影响。采用响应面法(RSM)建立二次回归模型,并对染色工艺进行优化。结果表明:在染液质量分数0.52%、染色时间4.2 h、染色温度72℃时,能够获得比较理想的染色效果,杨木单板的色差值为62.54 NBS。The author investigated the influence on fast grown poplar veneer color caused by acid-based dye stains at various concentrations,times,and temperatures.She developed a quadratic regression model between the influencing factors and the color performance using a response surface method.She found the optimized parameters were： 0.52% dye concentration,4.2 hours dyeing time,and 72 ℃ temperature.The veneer color difference under the optimized condition was 62.54 NBS.
