摘要
初步研究了赤桉和单板层积材声发射模拟信号源线性定位的可能性。研究结果表明:在该种材料上进行声发射线性定位是完全可行的,在木材上进行线性定位具有一定的方向性,这为未来对由该种材料所组成的结构进行整体安全监视提供了可靠的数据基础。
The thesis carried through study on linearity orientation of acoustic emission （AE） analog signals source in red river gum and LVL, it indicated presumably that linearity orientation of AE was all feasible for this kind of material. It was discovered linearity orientation has definite directions. The test study also attenuation characteristic of AE in its spread distance. This study data will accumulate hardy and basic data for whole safety and stake out of the structure of this material in the future.
