【摘要】 木材的弹性模量是衡量木材刚度特性的一个重要指标。由于传统静态弹性模量测量方法对木材本身具有破坏性且操作繁琐，耗时长，为了提高测试效率等，主要介绍了动态测试木材弹性模量的研究背景，并介绍了基于动力学与声学法动态测试木材弹性模量检测法的原理和研究进展，以期为木材无损检测技术领域的发展做出有益的探讨和总结。更多还原

【Abstract】 Elastic modules of wood is an important indicator of the stiffness characteristics of wood. Since traditional static elastic modulus measurement methods are destructive to the wood, cumbersome and time-consuming. In order to improve testing efficiency, etc. This paper mainly introduces the research background of dynamic testing, and introduces the principle and research progress of dynamic testing wood elastic modulus detection method based on dynamics and acoustics, hoping to make useful discussions and conclusions for the development of wood non-destructive testing technology.更多还原
