采用回归分析法，分析中密度纤维板（medium density fiberboard，MDF）剖面密度分布曲线特征参数与吸水厚度膨胀率、内结合强度、静曲强度和表面结合强度之间的相关性。结果表明，在相同平均密度水平下，MDF表芯层密度比与吸水厚度膨胀率呈极显著负相关关系（,P,＜0.001）。芯层密度、平均密度与内结合强度分别呈极显著相关性（,P,＜0.001）和显著正相关性（,P,＜0.01），同时芯层最低密度处不一定是试件破坏位置。受压面、受拉面的峰值密度（PD）与静曲强度的关系无显著差别；陡平型MDF峰面积的减小会导致PD与静曲强度相关性降低，平均密度与静曲强度呈极显著正相关性（,P,＜0.001）。铣槽深度处剖面密度与表面结合强度有极显著相关性（,P,＜0.001）。
The regression analysis method was used to analyze the relationship between the profile density distribution and thickness swelling rate, internal bond strength, static bending strength, surface bond strength of medium density fiberboard (MDF). The results showed that at the same mean density level, the density ratio of the surface-core layer of MDF has a very significant negative correlation with the thickness swelling rate (,P,＜0.001); the core density and the mean density have extremely significant correlation (,P,＜0.001) and significant positive correlation (,P,＜0.01) with the internal bonding strength respectively. The lowest density point of the core density was not necessarily the failure position of MDF boards. The peak density (PD) of the compression surface and the tension surface has no significant difference impact on the static bending strength. In the steep and flat type of MDF, the decrease of the peak area would weaken the effect of PD on the static bending strength. The static bending strength was extremely significantly affected by the mean density (,P,＜0.001). The profile density at the depth of the milling groove has an extremely significant effect on the surface bonding strength (,P,<,0.001).
