采用单因素试验法,分析马尾松溶出的纳米粒子特征,探索马尾松木材纳米粒子在索氏抽提、超声波抽提中的溶出规律．结果表明：(1)回归曲线显示, 在索氏抽提过程中,马尾松木材纳米粒子溶出量随时间延长呈上升趋势,但增长趋势逐渐减弱；(2)在索氏抽提过程中,以体积分数为评价指标时,溶出的纳米粒子直径主要集中在50．7～142nm；以数量分数为评价指标时,溶出的纳米粒子直径主要集中在37．8～106nm； 48

Based on the single-factor method, the fresh pinus massoniana lamb shavings were treated in the sorbitic extractor and supersonic wave extractor. The extractives were analyzed by ZETA and STZER to find out the leaching rule of nano particles from pinus massoniana lamb wood, hence to obtain the way to lower the negative effect of turpentine. The results were following as： （1） the regression curve showed that the extraction mass increases when the extracting time extends in the sorbitic extractor; （2） diameters of leached nano particles dist...
