| 摘 要： | 使用计算机断层扫描技术进行原木无损检测,通过对原木树种断层 CT 值的统计,对 CT 设备在检测过程中的窗宽与窗位进行了设定,同时拟合出了木材 CT 值一密度值的线性方程,为原木缺陷的无损检测及木材密度的测定提供一种新方法。

| Abstract: | Computer tomography technology was applied for log nondestructive testing.After calculating the CT numbers of the different log tomography images,this paper set the CT window width and window level during log testing.Then the linear equation of log CT number and wood density was carried out.A new method of wood nondestructive testing and wood density mea- suring was provided. |

| Keywords: | nondestructive testing wood density CT number window width window level |
