摘要通过光学显微镜检查了桤木和桉树的木材在通过Indurite工艺进行化学处理以增加木材硬度之前和之后。桤木的木材细胞浸渍方式与桉树有显著差异。在桤木木材中，所有细胞类型，例如。血管，纤维和射线，以类似的比例浸渍。相比之下，在桉树木材的浸渍材料主要局限于射线细胞和管腔的船只;其他类型的细胞要么没有浸渍或浸渍在非常少量。透射电子显微镜的桤木和桉树木材的纹理和孔隙度的孔膜的超微结构的差异可能是观察到的这些木材品种之间的差异的主要原因，就其可渗透性所使用的浸渍材料。
Summary The woods of Alder and Eucalypt were examined by light microscopy before and after a chemical treatment by the Indurite process to increase the hardness of the wood. The pattern of wood cell impregnation for Alder differed significantly from Eucalypt in some respects. In Alder wood all cell types eg. vessels, fibres and rays, were impregnated in similar proportions. In comparison, in Eucalypt wood the impregnation material was largely confined to ray cells and the lumina of vessels; other cell types were either not impregnated or impregnated in very small numbers. Transmission electron microscopy of Alder and Eucalypt woods suggests that ultrastructural differences in the texture and porosity of pit membranes may be the main reason for the observed differences between these wood species with regard to their impregnability by the impregnation material used.
