摘要
观察速生杨木素材和压缩率20~60％处理材的微观结构，测定其空隙度，探索杨木细胞压缩密化规律；建立数学模型，利用多元回归分析直接和间接导出木材绝干密度（ρ0）与测定空隙度（P1）、压缩率（r）的关系式分别为ρ0=-0.018P1-0.072r＋1.640和ρ0=-0.027P1-0.072r＋1.641。定量分析木材绝干密度与测定空隙度、压缩率之间的关系，为速生杨木压缩密化提供理论依据。
Observe the microstructure between fast-growth Poplar and its compression material with the ratio of 20%-60%, Measuring the Porosity;search the law Compression of Poplar wood cell, mathematical model is established to deduced the relationship of the mathematical model of oven-dry density （ρ0）, measuring porosity （P1） and compression ratio （r） directly and indirectly：ρ0=-0.018P1-0.072 r＋1.640 anρ0=-0.027P1-0.072 r＋1.641. the quantitative analysis of oven-dry density, wood compression ratio and measuring porosity would provide a theoretical basis for the densification of low-quality fast-growth wood.
