摘　　要：选择了8种主要云杉属树种木材,进行了弯曲振动条件下各项声振动特性参数的检测和比较,初步分析了振动特性参数与木材构造中晚材率变异系数之间的关系,探索了晚材率变异系数对乐器用材质量的影响,为深入评价云杉属乐器用材品质奠定了基础.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.
