摘要
用表面波传播法来测定刨花板的动态剪切弹性模量，并与利用弯曲振动试验测得的动态剪切弹性模量进行了比较分析，结果表明：利用表面波传播法来测定刨花板的动态剪切弹性模量是合适的。不同方法测得的弹性模量值不同．但它们之间存在着一定的内在联系。
A surface wave propagation method was proposed to measure the dynamic shear moduli of particleboard. The results indicate that the dynamic shear moduli by flexural vibration tests and surface wave propagation test were different. But there was a correlation between them. The surface wave propagation method was suitable for the measurement of dynamic shear moduli of particleboard.
