摘　　要：杨木是我国人工林培育的主要树种之一。为了加强对杨树木材的高效利用,改善杨木的渗透性,探究了常温下压缩空气微爆破处理中杨木试材初含水率、爆破压力和爆破次数对杨木渗透性的影响。结果表明,杨木木材试件经微爆破处理后,渗透性明显提高,初含水率和微爆破压力对杨木渗透性影响显著,微爆破处理的次数对杨木渗透性影响不显著。压缩空气微爆破处理对杨木力学性能影响不显著。Poplar is one of the chief species in planted forest cultivating. In order to extend the applications of polar and improve its permeability, test samples with different moisture contents are treated by compressed air explosion at different pressure and with different explosion frequencies. It is indicated that the compressed air explosion obviously improves the poplar permeability. Both initial moisture content and explosion pressure have notable effect on the permeability, but explosion frequency has little influence on it. Meanwhile, the compressed air explosion has little effect on the mechanical property of poplar.
