Dinizia excelsa Ducke under three different cut conditions were carefully analyzed. The morphology and stereometry of different wood cutting surfaces (longitudinal radial, longitudinal tangential, and transversal) were studied by SEM and AFM. The results obtained in this study suggest that both the height parameters and the advanced stereometric parameters of the surfaces did not reveal a significant difference, indicating that the spatial patterns do not change according to the type of cut. In this way, the surface microtexture does not vary depending on the cut type. Similarly, the Hurst's coefficients did not show any significant difference in the spectrum of the PSD fractal region. On the other hand, Minkowski functionals presented a morphological difference between the samples. These results showed that the microtexture of the wood surface does not change as a function of the type of cut submitted to the same polishing process.
对三种不同切割条件下的Dinizia excelsa Ducke 进行了仔细分析。通过 SEM 和 AFM 研究了不同木材切割表面（纵向径向、纵向切向和横向）的形态和体视学。本研究结果表明，表面的高度参数和先进的体视学参数均没有明显差异，表明空间模式不随切割类型而改变。因此，表面微观结构不随切割类型而变化。同样，在 PSD 分形区域的谱中，Hurst 系数也没有显示出任何显著差异。另一方面，Minkowski 函数在样本之间表现出形态差异。这些结果表明，在经过相同的抛光处理后，木材表面的微观纹理不会随切割类型的变化而变化。
