【摘要】 落叶松木材树脂含量的测定,一直采用传统的苯醇抽提法。为适应生产实践的需要,作者探索出了两种简易的测定方法:红外灯法和双氧水法。与传统的苯醇抽提测定结果相比,后两种方法的测定结果与之相近,均能反映出木材中树脂含量的变化情况。更多还原

【Abstract】 The determination of resin content in larch wood is always used the traditional Benzene—Al-cohol Extract Method. In order to meet the need of production practice, the authors present two simple quick determination methods, IR Lamp Method and Hydrogen Peroxide Solution Method. Compared with the results of traditional Benzene—Alcohol Extract Method, the results of later two methods are nearly the former. Therefore both of the methods can reflect the change condition of resin content in wood.更多还原
