        摘要：The modulus of rupture（MOR） and ultimate tensile strength（UTS） of dimensional larch（Larix gmelinii） lumber were tested according to ASTM D 4761-1996.The probability density function was used to describe MOR and UTS data.The results indicated that logarithmic distribution had the best goodness of fit with MOR and Weibull distribution had the best goodness of fit with UTS.The relationship between MOR and UTS was established as a power function from the cumulative distributions of MOR and UTS.

        摘要：Chinese white poplar（Populous tomentosa Carr.） specimens were treated under a heat and steam chamber with oxygen content less than 2 percent.The effects of temperature（170～230 ℃） and time（1～5 hours） were investigated on selected physical and mechanical properties of the specimens.The results showed that increasing both the temperature and time,both dimensional stability and modulus of elasticity were improved,but the modulus of rupture decreased.

        摘要：Reconstituted bamboo lumber（RBL） made with phenol-formaldehyde resin（PF）,thermo-treated RBL also made with PF,and a commercial RBL product were compared and evaluated for mold and decay resistance performance.The results showed that all RBL samples had good decay resistance and met the grade requirement.However,all products had a little effect on mould growth and none were able to prevent blue stain fungus.

        摘要：Benzyl chloride was used to modify wood powder to improve wood and plastic compatibility for better bonding.Benzylated wood powder was tested for surface free energy,polarity,and thermoplasticity and wood-plastic composites were evaluated for tensile and flexural strengths.The results indicated that benzylated wood powder had low free energy and polarity that improved compatibility with plastic.It was also observed that the wood/plastic composite made with benzylated modified wood had higher strengths.

        摘要：The author investigated the influence on fast grown poplar veneer color caused by acid-based dye stains at various concentrations,times,and temperatures.She developed a quadratic regression model between the influencing factors and the color performance using a response surface method.She found the optimized parameters were: 0.52% dye concentration,4.2 hours dyeing time,and 72 ℃ temperature.The veneer color difference under the optimized condition was 62.54 NBS.

        摘要：The ecological economy benefited directly and indirectly from China’s timber forests in 2008 when output reached 1.2 trillion RMB Yuan.The ecological economy benefits should be considered when evaluating industry contributions.Carbon storing by wood products and timber forest carbon fixing should be emphasized in both domestic and international carbon trade,national policies,and the carbon tax,or the ecology tax,to promote the wood products industry.

        摘要：The current status of wood identification technology,which primarily includes macro-and macro-/micro-identification techniques,was reviewed in this paper.The description of the glossary,the definitions of wood features,and the assistant tools and the basis of wood nomenclature were explained.Three new technologies,DNA markers,stable isotope,and near-infrared spectroscopy（NIR）,were described.The authors believe that the new technologies could be used to identify the botanical species and trace the location from where the wood originated.However,further research and development should be enhanced for their commercialization in the wood identification field.

        摘要：To reduce wood drying energy consumption,the authors developed a solar drying kiln for drying wood.They fixed heat pipe and holistic collectors,and used paraffin to improve heat collecting and storing capacity.The kiln was used to dry a stack of poplar lumber and compared it with air and conventional kiln dried poplar lumber.The results showed that the heat utilization efficiency for holistic and heat pipe collectors were 22.2% and 62.4% respectively.The solar drying process had a faster drying speed and was less dependent on the weather.It was also noted that the solar drying process had about a 70.9% energy savings compared with conventional drying.

        摘要：The authors of this paper used a glass-fiber reinforced polymer（GFRP） to improve the properties of laminated paulownia panels.Two types of panels were made with GFRP placed in different locations（core and face）.The result showed that there were differences in the bonding strength,modulus of rupture and impact toughness between the two group of panels.The authors expected that these panels could be used as furniture and door parts.
