摘　　要：采用低分子量酚醛树脂对速生杨木进行增强浸注,改性后统计分析改性材的质量增加率情况,以了解浸注性的分布规律。结果表明:速生杨木改性后质量增加率的数据整齐,集中在平均数附近。经过假设并检验后得出,速生杨木改性材质量增加率服从均值为41.87%、总体标准差σ为0.069 0的正态分布;并由此计算出速生杨木改性后,质量增加率落在参考区间为35%～55%的概率值。Fast-growing poplar wood was modified with PF resin.The distribution rule of the impregnation of modified wood was analyzed statistically.The results showed that the values of weight percent gain（WPG） were concentrated around the average and obeyed normal distribution（mean：41.87%,standard deviation：0.069 0） after testing the hypothesis.The probability of WPG falling between 35% and 55% was calculated accordingly.
