摘　　要：采用Plato水热-常压过热蒸汽联合热处理工艺对云杉木材进行热处理,对不同温度水平处理前后云杉木材的顺纹抗压强度进行了测试。结果表明,未处理云杉木材的顺纹抗压强度为65.75 MPa,经130、145及160℃水热-常压过热蒸汽热处理后云杉木材的顺纹抗压强度分别为70.86、68.07和64.15 MPa,并运用化学成分分析法对热处理工艺对云杉木材顺纹抗压强度的影响进行了分析。Spruce wood samples were thermally treated by Plato process, in which wood was first subjected to hydrothermal treatment, and then treated in superheated steam. The compressive strength parallel to grain （CSPG） of the treated samples was studied. Wet chemical analysis was performed to analyze the influence of heat treatment on the CSPG of spruce wood. The results show that the average CSPG of the samples treated at 130℃, 145℃ or 160℃ is respectively 70.86 MPa, 68.07 MPa and 64.15 MPa, compared to 65.75 MPa of the control samples.
