摘要: Needle fir (Abies nephrolepis) wood was surface densified at two compression ratios (16.1 and 21.7 %), hot-pressing temperatures (160 180 °C) for a pressure holding duration of 10 min. Subsequently, it thermally treated (180 200 1 h. The equilibrium moisture content responses radial swelling strain were calculated thirteen types adsorption specimens under water soaking, respectively. Compared with untreated (control) but non-thermally ones, the hygroscopicity post-treated significantly decreased. Both temperature ratio showed insignificant influence on all specimens. Under current test conditions, increase thermal post-treatment decrease among specimens, deformation impact increasing according to statistical analysis.
