摘要
对樟子松活立木、原木及其板材的应力波传播速度进行检测,得出活立木与原木的应力波传播速度非常接近;樟子松原木段与其板材的应力波传播速度具有较大的相关性,相关系数为R2=0.6,因此可以通过活立木的应力波传播速度来预测原木制成板材后的应力波传播速度。
The stress wave propagation velocities of standing timber, log and board of Mongolian Scotch pine is detected, with the result showing that the stress wave propagation velocities of standing timber and log are very close and the stress wave propagation velocities of log sections and board of Mongolian Scotch pine show great correlation,with a correlation factor of R2=0.6. Therefore, the stress wave propagation velocity of board made of log can be forecast based on the stress wave propagation velocity of living timer.
