        摘要：Non woven liner was pretreated with different chemicals and the influence to the wood fiber synthetic fiber composite was studied. The result indicated that pretreatment could eliminated the adverse effect of non woven liner to the composite. The best dosage of chemicals for pretreating is 100% of the weight of the non woven liner.

        摘要：The study found that the major factors affecting dye up take were the constitution of the liquor and the parameters of dyeing process. The 0.5 mm sliced Paulownia elongata veneer was dyed in an experiment by the acid bright red. It was shown that NaCl produced an obvious effect. The percent of dye up take increased with the increase of NaCl concentration and then decreased after highest point at 1%. The dye up take increased with increase of liquor temperature. The percent of dye exhaustion gradually ascended with the time going in experiment until to reach the adsorption equivalent state. The result was satisfied for the 0.5 mm sliced Paulownia elongata veneer at 90 ℃ for 3 h. The dye up take was different with the change of dye concentration, and the best concentration was 1%. The adsorption was different with the change of the bath ratio of the liquor to wood. The suitable bath ratio was 15. Acetic acid took an active part in promoting the percentage of exhaustion with the best concentration of 1.5%.

        摘要：The house climate (including temperature and relative humidity of inside and outside of wall surface, the distribution in vertical space of temperature and relative humidity inside, etc.) of oriented structural board (OSB) building and brick building in winter and summer were tested by automatic recorder. It was indicated that the house climate of OSB building (the structure of wall is OSB+glass wool+OSB) was better than that of the brick and concrete building for human’s health. The indoor temperature of OSB building is steady.

        摘要：Acacia mangium belongs to the fast growing plantation species in the tropical area, the diameter of the tree trunk is small, and the proportion of the juvenile wood is large. The wood is easy to dry, but the collapse and inner crack occurs easily, so a low temperature schedule is recommended, and more conditioning should be done, so that drying stress and plastic distortion can be reduced, and the collapse and inner crack can be avoided. The integrated method of air drying and kiln drying is recommended to reduce drying time, energy consumption, and drying cost.
