摘要：
The high-grade resource recovery on acetic ether extractives in E. camaldulensis wood was analyzed by means of Py-GC/MS, and relative content of each component was determined by area normalization. Results showed that main constituents of acetic ether extractives were ergosta-4,6, 22-trien-3.beta.-ol (12.53%), 1-phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10,10a-octahydro -1,4a-dimethyl-7-(1- methylethyl)-, methyl ester (10.87%),oleic acid (10.65%), etc. So it can be concluded that rare medicinal materials and spice are not only abundant in acetic ether/acetone extractives, but also its by-products can be used as top-grade cosmetics, bioenergy etc.

摘要：
Now environment protection and resources conservation is rising on a global scale and carried out a green wave protection. The green rampart that formed on foreign trade was exerted a tremendous influences for product export in China. Therefore, the development countermeasure is urgent to be studied in order to help the industries in China placidly pass through the crisis. Based on survey reports and large numbers of literature and data about particleboard processing, the paper analyses the favorable conditions in developing the green foodstuff in China and puts forward some strategies and tactics in breaking through the green barriers and opening up the international markets. On this basis, the development countermeasure with Chinese Characteristics were proposed to promote healthy development of particleboard industry.

摘要：
There is the theology of the plywood formaldehyde-emission which is similar to the solid and the liquid. The mature theory of rheological is applied to study on the mechanism of the plywood formaldehyde-emission in this paper, and the loose models of the plywood formaldehyde emission are created. The formularies F-M = F(0)e(-0.1429t). and F-k = P0/kappa(1 - e(-0.1429t)) can be received and used to describe the influence of the placed time of sawed test piece to the plywood formaldehyde-emission. The deviation between the theory value and the test value is 0.52 mg/L.
摘要：
Lignincellose fiber was one of special fibers which were used for textile fiber, paper, engineering plastics, etc. And Eucalyptus camaldulensis has been widely planted in south China. Therefore, based on the single-factor method, the fresh Eucalyptus camaldulensis wood flour were treated by means of the alkali liquor extraction to obtain the best purification of lignincellose fiber. The results are as follows: During the the sorbitic-extracting process, MPC had significant influence on leaching rates of wood extractives and hemicelloses at 0.01 level. And sort of alkaline had significant effect on the leaching rates at 0.05 level. The optimum concentration of NaOH liquor, KOH liquor, LiOH liquor was 20.0%, 17.5%, and 12.5%, separately. The leaching rates was the highest when extraction time was 24 h. The optimum alkali liquor was NaOH liquor. The next was KOH liquor, LiOH liquor.

摘要：
Now the wood multi-layer floor industry in China is not relating to ecological environment construction for severe pollution, low utilization rate of raw materials, high energy consumption and low products extra value. Therefore, the development countermeasure is urgent to be studied in order to help the wood multi-layer floor industry in China placidly pass through the crisis. Based on survey reports and large numbers of literature and data about wood multi-layer floor, the developing present situation of wood multi-layer floor industries in China were in detail summarized. On this basis, the ecological management mode of finishing technology of wood multi-layer floor in China were proposed to promote healthy development of wood multi-layer floor industry.

摘要：
Wood-based composites is widely used in building and interior decoration field. However, it is easy for wood to get burnt, and abundant toxic smoke generating during the burning process has caused great casualties and property loss. In this study, poplar wood was chosen as test materials, and three fire-retardant were selected, i.e. the inorganic X type fire-retardant and the organic fire-retardant named F type, and the Z type fire-retardant which is an ordinary organic and inorganic combination fire-retardant and contains element Cl and N. Then after different treated process, three types of gluing composite lumbers were prepared. Thereafter, DSC, TG etc were adopted, and the fire-retardant, smoke-suppressant and mechanical performance of lumber were compared and evaluated. The results indicated that : (1) In a certain range of fire-retardant concentration, with the increase of concentration, all of these three fire-retardant had a much better fire-retardant and smoke-suppressant performance while the bonding strength of composite didn't show much variation and met the requirement of GB. (2) For the F type fire-retardant, when the concentration and process technique were the same, the fire-retarded performance of Y type was better than the other two types, and it also had a good smoke-suppressant performance. (3) X type fire-retardant had an excellent fire-retardant and smoke-suppressant performance when its concentration was relatively large. (4) For Z type fire-retardant, it had a good fire-retarding performance with a relatively small smoke amount, but some toxic gas such as HCI and NH(3) was generated.
