本文分别对红松、白桦和黄波罗三个树种的腐朽材和健全材,用电子能谱仪和X射线衍射仪,测定了样品的氧碳含量和结晶度的变化,实验结果表明,腐朽材的相对氧含量上升,而结晶度下降。随腐朽程度的不同,碳氧含量的比例不断变化,在腐朽极为严重的情况下,氧的含量可能高于碳的含量。说明腐朽的主要机制是氧化过程,及结晶区破坏和结晶度下降。本文是木材腐朽检测的基础研究之一,为木材腐朽检测的研究提供基础数据和理论依据。
In this paper, the decaying and sounding materials of the three tree species of Pinus koraiensis, Betula platyphylla and Huangporo were determined respectively by means of electron spectroscopy and X-ray diffractometer. The results showed that the rotten The relative oxygen content of the material increases, while the crystallinity decreases. Depending on the degree of decay, the proportion of carbon and oxygen changes continuously, and in the case of extremely decadent decay, the oxygen content may be higher than the carbon content. That the main mechanism of decay is the oxidation process, and the destruction of crystalline regions and crystallinity decreased. This paper is one of the basic research on wood decay detection, providing the basic data and theoretical basis for the study of wood decay detection.
