| 摘 要： | 杨氏弹性模量是反映树干或板材抗弯、抗压强度的重要指标,是开展林木材质育种研究的重要内容。笔者通过对多株树分别采用FAKOPP(应力波速度测定机)和敲打法2种不同方法测量同一树干的杨氏弹性模量,并对2种测定数据进行相关性分析,检验用FAKOPP测量立木状态下树干弹性模量的准确性。通过对杨树试验证明:二者具有很强相关性,说明利用FAKOPP的方法能准确评价树干杨氏弹性模量大小。

| Abstract: | MOE reflects log or lumber material anti-bend,important index of the anti-press strength,which is the important contents for developing forest wood breeding.This test carries on relativity analysis by adopting FAKOPP(Microsecond Timer) and knock method's two kinds of different methods to measure MOE of the same tree trunk for mutil-trees respectively,as well as two kinds of measuring data,test the accuracy of tree trunk flexible mold under standing status by using FAKOPP.It can evaluate exactly the size of the trunk MOE by using FAKOPP method through a certification to Populus test. |
