摘　　要：一种利用共振法与DSP相结合,对木材的弹性模量进行无损检测的便携式系统。该系统能够准确得到木材的固有频率,进而求出木材的弹性模量来对木材的质量进行准确的判断。A portable system that combined DSP and resonance method to nondestructively detect the elastic modulus of the timber is introduced in this paper. Such a system can accurately obtain the natural frequencies of wood, in order to calculate the elastic modulus of wood so as to judge the timber quality.

关 键 词：DSP 振动法 弹性模量 便携
