选择７种我国具有代表性的云杉属木材及１种做对比用的美国产西加云杉试材。分析了纤维素结晶度对木材声振动特性参数的影响。根据纤维素结晶度与木材声振动特性参数之间存在的关系．总结出一些基本规律．云杉属木材纤维素结晶度达到５９％后．木材声振动特性可达最佳。
Choose 7 species of representative Picea wood and 1 species of comparative Xega spruce material for comparison. The influence of cellulose crystallinity on acoustic vibration characteristics of wood was analyzed. According to the relationship between the crystallinity of cellulose and wood acoustic vibration characteristics parameters. Summed up some basic rules. Picea wood cellulose crystallinity reached 59%. Wood sound vibration characteristics up to the best.
