摘　　要：以25mm厚杨木、桦木、柞木厚板为研究对象,进行微波处理,通过改变木材初含水率、辐射时间和微波辐射强度,以木材真空加压浸渍处理得到的增质率和上染率为评价指标,研究微波处理条件与木材染色性能的关系。结果表明:木材的增质率和上染率在含水率为30%时最大,并随初含水率的增大而减小,随微波处理时间的延长和强度增大而增大。In this paper, the 25 mm-thick poplar （Populus tremula ）, birch （Betula platyphylla ） and the oak （Quercus mongolica） by microwave treated as the object, were treated with the different microwave radiation intensities, treating time or moisture content（MC） before microwave treating, then vacuum and pressure impregnation in the treatment tank. It is discussed that the relationship between the conditions of microwave treating process and the permeability of dyed wood evaluated by the water absorption ratio（WAR） and the dye uptake. The result showed that the WAR and the dye uptake,the maximum at 30% （MC） ,increase with the decreasing of moisture content or increasing of microwave radiation intensities, treating time.
