Development Tendency and Research Progress of Non-destructive Testing for Wooden Material's Defects

从基于成像技术、信号传播速度变化、人工模拟缺陷和信号处理的木质材料缺陷无损检测以及木质材料缺陷对其力学性能的影响5个方面论述了木质材料缺陷无损检测的研究进展,简要分析了目前研究中存在的主要问题及其发展趋势。

Non - destructive testing for defects is an important technology for utilizing of wooden material effectively and reasonably. Facing the shortage of wooden material in the world nowadays, the effective non - destructive testing for wooden material＇ s defects appears importance. The main course of researches on non - destructive testing for wooden material＇ s defects is reviewed, including the imaging technique, the changing of signal propagation velocity, defects of manual simulation, signal processing of non - destructive testing for wooden material＇ s defects and influence of wooden material＇ s defects upon meChanical property. Then the existing problems of non - destructive testing for wooden material~ defects are analyzed in brief,and development tendency is forecasted.
