<正>用Ｘ射线密度计测量刨花板和纤维板在厚度方向的密度分布，从而求得密度梯度的平均值和最大值。同时研究了胶和木材的质量吸收系数以及其它因素对测量结果的影响。

Density distribution of fiberboard and particleboard in thickness was measured by X-ray densicometry on the thickness direction. Density gradients were also determined.In the meantime,an investigation was made into the influence of some factors on the measuring results.
