USE OF AN IN PROCESSING WOOD & WOOD BASE MATERIALS AND MATERIAL-EVALUATION

本研究的目的是组织利用声发射技术进行研究的研究人员，以促进他们的研究，并建立能够应用于木材及木材基材加工和材料评价的声发射方法。本研究涵盖了目前ae应用的所有领域；即的AE源波分析表明通过AE源的AE信号形式,讨论使用AE在木头断裂的条件,分析断裂过程的胶粘剂层和刨花板强度评价和检测木和木基材料中的缺陷,推定在木材干燥应力,AE监测在木材切割过程中,使用木材和AE监测检测白蚁活动断裂过程的分析。这些研究得到了很好的结果，为未来指明了方向，特别是最后两项研究产生了几个第一个发现，并得到了世界范围的评价。

The objects of this research were to organize the researchers, who have used AE in their studies, in order to advance their studies and and to establish the AE methods capable of applying to processing wood & wood base materials and material-evaluation.This research covered all the fields where AE-is used at present; that is, a source wave analysis of AE which indicates at the source of AE through AE signal forms, a discussion of the condition of fracture in wood using AE, an analysis of fracture processes in adhesive layer and particle board, strength evaluation and detection of defects in wood & wood base materials, presumption of drying stresses in wood, AE monitoring in wood cutting processes, using AE monitoring to detect termite activity in wood and an analysis of fracture process in paper. These studies got good results to indicate the way in the future and, especially, the last two studies produced several first findings and are world-widely evaluated.
