Applications and development of CT in the wood non-destructive testing
-
摘要: 介绍了计算机断层扫描技术(CT)技术在木材无损检测领域中的发展情况和独特优势,从方法应用、结果判定、测试范围等方面详细阐述了国内外木材计算机层析成像检测的研究现状,着重指出它在木材宏观构造识别、早晚材密度判定、木材内部缺陷预测、裂纹扩展过程的超高速扫描以及微观构造分辨等方面取得的技术成果。最后强调结合木竹材材性特征开发相应的CT无损检测技术,为木竹基础科学研究以及高效利用提供技术支持。参37Abstract: The paper reviewed the development and unique advantages of CT technology in the field of nondestructive testing of wood,elaborating on the status of timber CT inspection from method application,characteristics determination fest range. It highlighted the achievements of CT technology in the recognition of timber macro-structure,determining density of the early wood and late wood,predication of wood internal defects,ultra-high-speed scanning of crack propagation process and identification of microstructure. Finally,put stress on developing the corresponding CT technology wich combined with the characteristics of wood and bamboo,that provide technical support for wood and bamboo basic scientific research and utilization.[Ch,37 ref.]
