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。
對樟子鬆活立木、原木及其闆材的應力波傳播速度進行檢測，得齣活立木與原木的應力波傳播速度非常接近；樟子鬆原木段與其闆材的應力波傳播速度具有較大的相關性，相關繫數為R2=0.6，因此可以通過活立木的應力波傳播速度來預測原木製成闆材後的應力波傳播速度。
대장자송활립목、원목급기판재적응력파전파속도진행검측，득출활립목여원목적응력파전파속도비상접근；장자송원목단여기판재적응력파전파속도구유교대적상관성，상관계수위R2=0.6，인차가이통과활립목적응력파전파속도래예측원목제성판재후적응력파전파속도。
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.
