摘　　要：本文选择了 8种主要云杉属树种 ,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 ,并分析了这些参数和木材构造中生长轮宽度、晚材率之间的关系 ,为深入评价云杉属乐器材品质 ,确立乐器材选材中合理应用木材生长轮宽度。In this paper eight \%Picea\% genera wood were selected to determine and compare the sound vibration parameters of Young's module,loss tangent (tan δ ) and E/G under bending vibration condition.The relationship between these parameters and growth ring width and latewood percentage was analyzed.The results of this study could be a basis of evaluating the quality of \%Pices\% genera wood for musical instrument and establishing the method of reasonably using the parameters of growth ring width and latewood percentage in the selection of wood for musical instrument production.

关 键 词：云杉属木材 生长轮宽度 晚材率 声振动参数 振动性能
