摘　　要：选择了 7种我国具有代表性的云杉属木材及 1种作对比用的美国产西加云杉木材试件 ,考察了次生壁S2 层纤丝角对木材声振动特性参数的影响 ,云杉属木材次生壁纤丝角在 9°～ 1The objective of this study is to make clear the relationships between microfibril angle and vibration properties of eight Picea species, which grow in America, Sichuan, and Heilongjiang Province of China experimentally. The results show that eight Picea species have proper microfibril angles, and when the microfibril angle reaches 9°～13°, vibration properties of Picea species will be optimal.
