Imported radiata pine wood samples were heat-treated at four temperatures ranging from185℃ to 230℃ for 4 hours.At 215℃,the wood samples were treated for three,four and five hours,respectively.The bending properties and dimensional stability of the samples were tested.Results showed that the modulus of elasticity（MOE） of the samples fluctuated with the increase of treating temperature.The MOE reached the maximum value when treating temperature was 200℃.Meanwhile the modulus of rupture（MOR） of the samples kept falling as the treating temperature increased.The MOE and MOR were all slightly decreased when the treating time extended.The heat treatment improved the dimensional stability of the samples significantly.The equilibrium moisture content,moisture excluding efficiency and anti-swelling efficiency of the samples were more affected by the treating temperatures than the durations.
