摘要：
Paulownia is one of the most important fast-growing species in China and the existing live wood stock volume of paulownia is 0.8 billion m(3). However, paulownia wood could discolor easily, which limits its industrial utilization and reduces the economic benefits. Therefore, the new chemical treated technology was applied to prevent paulownia wood from discoloration based on the lower wasterwater and chemical pollution. At the same time, the optimization of the antitamish technology has been systematically investigated. The results showed that the optimal formula for antitamish treatment was that: the concentration of the main antitamish agent, 1.5%; the concentration of the assistant antitarnish agent, 0.05%; the concentration of color protection agent,1% and the concentration of surfactants 0.1%. And the optimized innovative technology is that time is 6h, pressure is 0.4 similar to 0.6Mpa and temperature is 55 degrees C.

摘要：
Formaldehyde release not only pollutes indoor environment, but also severely impairs health of human body. Therefore, a novel technology using the mold pressing was introduced to realize binderless agglutination in wood-based panel and to earnestly safeguard the health of consumer and the indoor environment. Thermo-gravimetric analysis and conventional measurement were performed to determine the physical and mechanical properties of woodceramics body. The results show that temperature, time and pressure of moulding process all have significant effect on physical-mechanical properties, and that the mechanical properties of new binderless woodceramics body is superior to traditional medium density fiberboard.

Development Model;Bamboo industry in China;Development Countermeasure;Economic Crisis
摘要：
The global economy is facing economic crisis at present. And all the industries are face to serious problem relative to their fates. In addition, the bamboo industry in China is not relating to ecological environment construction for low utilization rate of raw materials, high energy consumption and low products extra value. therefore, the development model and countermeasure is urgent to be studied in order to help the bamboo industry in China placidly pass through the crisis. Based on survey reports and large numbers of literature and data about bamboo processing, the present conditions of bamboo industry in China was analyzed systematically. On this basis, the development model and countermeasure with Chinese Characteristics were proposed to promote healthy development of bamboo industry.
摘要：
In order to overcome the above-mentioned negative effects, the fresh Chinese-fir shavings were extracted in KOH soltion, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17.5%. The micro/nano particles in Chinese-fir shavings would be discharged sufficiently in the KOH solution with the increaing of extracting time.(2) The diameter the micro/nano particles of wood extractives and hemicellulose is comparatively scattered according to volume fraction. Micro/nano particles in the diameter of 91.3-342 nm, 91.3-342 nm, 342-1720 nm is the most at the extracting time of 3h, 16h, 24h, respectively (3)The diameter the micro/nano particles of wood extractives and hemicellulose is chiefly between 342nm and 6440 nm according to number fraction. Micro/nano particles in the diameter of 91.3-342nm, 91.3-342nm, 91.3-342nm is the most at the extracting time of 3h, 16h, 24h, respectively.
摘要：
Bamboo is the important resource for the sustainable development of Chinese forestry. The researches on the extracts of bamboo were mainly focused on the leaf, bark, shoot and distillate, however, the components of bamboo root extract is unresolved though it has the effect to cure some intractable diseases. Therefore, pyrolysis- GC/MS technology was used to identify and analyze the top value-added biomedical and bioactive components of benzene/ethanol extract of Moso bamboo root. The extract was pyrolyzed at 750 degrees C in helium atmosphere, and then the pyrolyzate was analyzed by online-linked GC/MS. Relative content of each component was determined by area normalization. 69 compounds representing 99.14% were identified from 74 peaks, and the main components were as: 1,3-benzodioxole, 5-(2-propenyl)- (6.83%), 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester (6.02%), phenol, 2,6-dimethoxy- (5.03%), 4.2.2 propella-2,4,7,9-tetraene (4.82%), benzofuran, 2,3-dihydro- (4.39%), phenol, 2,6-dimethoxy-4-(2-propenyl)- (total 4.24% from 3 peaks), 3',5'-dimethoxyacetophenone (4.05%), benzoic acid, butyl ester (3.48%), benzene, 1,2-dimethoxy-4-(2-propenyl)- (3.02%), mequinol (2.95%), eugenol (2.79%), etc. The result showed that the pyrolyzate of benzene/ethanol extract of Moso bamboo root is rich in biomedical components, and also contains some bioactive components which can be used as top value-added materials of high-grade spice, cosmetic, food, and chemical.
摘要：
Green composites made from bamboo fibers and biodegradable resins were fabricated with press molding. On the basis of the Weibull distribution and the weakest-link theory, the statistical strength and distribution of bamboo fiber were analyzed, and the tensile strength of green composites was also investigated. The result confirms that the tensile statistical strength of fiber fits well with two-parameter Weibull distribution. In addition, the tensile strength of bamboo fiber reinforced composites is about 330 MPa with the fiber volume fraction of 70%. This value is close to or higher than that of other natural fiber reinforced green composites.

摘要：
Paulownia slices are often used in the process of the teaching on plant anatomy. However, it is much difficult to obtain the perfect paulownia slices,which are susceptible to be polluted,brown stain,and vitrification during slicc's preparation. These are stupendously similar with some questions that we fall across in education, such as university students' degeneration, psychological illness and flimsiness.Therefore, in this paper, we attempt to give ideological methods to solve some questions in education through the discussion on the paulownia-slice preparation.

advanced materials of bamboo;industry design;benefit distribution;integration mode
摘要：
Industry design should aim at achieving a sustainable and optimal development of the corresponding industries relative to the target industrial chain, and it is necessary to consider the rational distribution of economic benefit in the industrial chain. Advanced materials of bamboo industry is the intermediate industry combining the primary industry of the original bamboo resource with great ecological benefit and the high-technique industry with large economic benefit. However, the relative low economic benefit of primary-industry population has seriously limited the stable increase of ecological resource. Therefore, the industry design should consider increasing the income level of primary-industry population. In this paper, a mode entitled "rear unitization and integration of high-technique industry" was presented to promote the development of the primary industry by adopting the mechanism of benefit distribution.
