摘要:After reviewing the present status and prospects of the wood industry in the world, the author suggested that in response to the economic globalization and China’s entry into the WTO, the Chinese wood industry should further develop IT application, optimize and upgrade industrial structure and raise quality of labor force, blazing a new trail to industrialization featuring high scientific and technological content, good economic return, low resources consumption, little environmental pollution and a full display of advantages in human resources, so as to enhance its international competitiveness to supply customers better products and services at lower cost.
摘要:This paper reviewed the status of China’s forest resources, wood supply, and demand. The study concluded that the way to solve the wood material shortage problem is to establish industrial plantations of fastgrowing tree species. It was further suggested that in order to encourage individuals or peasants to plant trees, a series of favorable government policies and administrative measures should be implemented.
摘要:This paper addressed the origin, research objectives and some solutions for solving the problem of indoor environmental contamination. It examines the health concerns posed by air contaminants, as well as detailed measures to improve indoor air quality. The authors reviewed current research on indoor environmental contamination, both in China and abroad, and measures to control it. Finally, the authors made some suggestions to promote research in this area.

摘要:This study tested the mechanical behavior of Moso Bamboo (Phyllostachys pubescens) under large compression deformation at different temperatures and directions (radial, tangential and longitudinal) with restricting conditions. Based on the experimental data, the relationship between stress and strain was established. The results showed that bamboo revealed the same mechanical properties under compression in both radial and tangential directions. The entire deformation process could be divided into three stages: linear plasticity, feeble linearity strengthening after yielding, and power strengthening.

摘要:Three types of fiberboard were made to study the influence of adhesive on heat conduction during the hotpressing cycle. The resin systems studied were PF, UF and a binderless system. Temperature recordings were made at the core of the fiberboard mat during hotpressing. Software was used to analyse the temperaturetime curves formed by the data, but there was little difference between the three curves. From the results, the authors concluded: 1) the effect of adhesive type on heatconduction through fiberboard mat during hotpressing is negligible and 2) the heatconduction property of bindeless dryprocessed fiberboard is also suitable for common dryprocessed fiberboard.
摘要:Joining the WTO has had a major effect on China’s economy and furniture manufacturing industry, for both Wuhan, the capital city of Hubei Province and the country as a whole. This paper investigates and analyzes the current status of furniture market in Wuhan, and forecasts the future of China’s furniture industry and the market for Wuhan after China joined the WTO. The authors also present some suggestions for Wuhan’s furniture manufacturers.
摘要:This paper presented a standardized drawer design based on the 32 mm system and 50 mm cabinet width modulus. Further discussion was focused on dimensional specifications featuring interchangeable drawers. Implementation of these features would further drawer standardization and improve the design of the 32 mm system for furniture.

摘要:Treatment for wood dimensional stability is an effective measure to improve wood properties and broaden its use. This paper reviewed the research on the dimensional stability of wood, including several principle treating methods as well as their mechanisms, effects and applications. It offers a general reference for those engaged in this field.
摘要:The deresinating mechanism and methods for Masson’s Pine( Pinus massoniana ) wood were discussed in this paper. The author deemed the only process necessary for deresinating Masson’s Pine was turpentine removal. Therefore, the removal ratio of turpentine, the spillage of oleoresin, brightness and wood strength as the quality testing indexes for deresinated wood were redefined. Furthermore, an experiment on mechanical properties of deresinated Masson’s Pine was conducted. Results showed that after treating with 0.5% nitridocompound at 100 ℃ for 1.5 h, the wood still had enough mechanical strength for finger jointing and was suitable for furniture and decorative materials.

摘要:Chinese Fir (Cunninghamia lanceolata), one of the main fast growing plantation species, is widely grown in southern China and is an excellent wood species for use in parquet flooring. Using planted Chinese Fir as the bottom layer and precious hardwood veneer, such as Padauk (Pterocarpus) as the surface layer, then coated by UV paint, the parquet has not only an excellent appearance, but also better physical and mechanical properties.
摘要:The modulus of elasticity (MOE) of the wood frame structure in the Beijing Yongle Great Bell Museum was determined, on site, by using ultrasonic nondestructive techniques.This paper can be used as a good reference for future studies applying the ultrasonic nondestructive evaluation method in ancient woodstructure buildings.
