| Abstract: | Eight Picea generas wood were selected to examine and compare their Youngs module,loss tangent (tanδ), E/G parameters under bending vibration situation. The relationship between vibration property and variance coefficient of latewood percentage was analyzed to explore their effects to the P. genera wood quality. It established the foundation for how to evaluate the quality of P. generas instrument wood. |
