摘要：
Pinus has been put into mass production. However, many heat release volatiles would produce air pollution during drying process. Therefore, the heat release behavior of Pinus biomass was studied by TD-GC/MS. The main constituents were at 100 degrees C 1,4-methanoazulene,decahydro-4,8, 8-trimethyl-9-methylene-(30.6%), 1,4-methanoazulen-9-ol,decahydro-1,5,5,8a-tetramethyl-(14.85%), 1,2,4-methenoazulene, decahydro-1,5,5,8a-tetramethyl-(8.56%), Ir-.alpha.-pinene(7.92%), epiglobulol(4.57%), bicyclo[2.2.1]heptan- 2-one, 1,7,7- trimethyl-, (1r)- (4.33%), caryophyllene oxide(3.37%), etc. And the main constituents at 110 degrees C were 1,4-methanoazulene, decahydro-4,8, 8-trimethyl-9-methylene-(40.31%), 1,4-methanoazulen-9-ol, decahydro-1,5,5,8a-tetramethyl-(15.35%), .alpha.-pinene(8.88%), bicyclo [2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)- (5.73%), cyclohexane-1,3-dione, 2-allylamin omethylene-5,5-dimethyl-(5.24%), naphthalene, 1,1'-(1,2-ethanediyl) bis [decahydro-(4.83%), spiro[5.5]undec-2-ene,3,7,7-trime thyl-11-methylene-(4.05%), etc. The heat release volatiles of Pinus biomass was safe to people during drying process.
摘要：
In order to select the optimal modification method of fire-retardant preservative formulationtion ratio for glued structural lumber of wood-based bridge deck by analysing the bonding strength of experimental samples. Through range analysis, the experiment results showed that: the mode of the best fire-retardant preservative formulationtion ratio was 45ml/(40cm X 40cm) preservative, I g/(40cm X 40cm) flame retardant and 18h soaking time of adhesion. And the glued structural lumber had enough bonding strength under high flame-retardant properties, which was fit to make glued structural lumber for wood bridge.

摘要：
This thesis aims to select the optimal assemble patterns of wood species for structural lumber for wood-based bridge by analysing the bonding strength of eucalyptus veneers, poplar veneers and bamboo mats. Through variance analysis, the experiment results showed that: the compound mode: bamboo mat was used as the core panel, eucalyptus veneers as the surface panel, and the bonding strength is above the national standard. What draws special attention was that thickness of eucalyptus veneers was above 1.3 mm to crack.
摘要：
Manglietia glauca leavies has a strong bactericidal Manglietia health capacity. However Manglietia glauca leavies are still underutilized and hence wasted. In order to better utilize Manglietia glauca leavies resources, the biomedicine resource of benzene/alcohol extractives from Manglietia glauca leavies were analyzed by GC/MS. Relative content of each component was determined by area normalization. The main ingredients of benzene/alcohol extractives of Manglietia glauca leavies were tritriacontane(4.84%), 9-octadecyne(4.19%), ethyl alcohol(3.23%), 2-furanmethanamine, tetrahydro-(3.1%), .beta.-sitosterol acetate(2.84%), vitamin e (2.77%), triacontanoic acid, methyl ester(2.67%), .gamma.-sitosterol(2.33%), nonacosane(2.15%), 5-acetoxy-6-methyl-12,13-dioxa-tricyclo[7.3.1.0(1,6)]tridecane-10-carboxylic acid(2.14%), d:b-friedo-b':a'-neogammacer-5-en-3-ol, (3.beta.)- (1.88%), pyridine-3-carboxamide, oxime, n-(2-trifluoromethylphenyl)- (1.84%), 1-heptadecyne(1.84%), friedelan-3-one(1.75%), 5-eicosene(1.72%), dibutyl phthalate(1.7%), 2,3,5,6-tetrafluoroanisole(1.6%), phenol, 4,4'-thiobis-(1.5%), etc. The results obtained fully indicated that the benzene/alcohol extractives of Manglietia glauca leavies had the great potential of noble natural biomedicines.
摘要：
Bamboo leaves has been used to heal some diseases in the Chinese Folk for a long time. In order to explore the wide biomedicine utilization, the chemical components of benzene-alcohol extractives from the fresh bamboo leaves was studied by Py-GC/MS. The results indicated that the main components were decanoic acid, 1,2,3-propanetriyl ester(5.6%), 9-octadecyne(3.21%), tricosane (2.88%), .gamma.-sitosterol(2.81%), phenylpropionic acid,.alpha.-amin o-2-fluoro-4-hydroxy-5-methoxy-(2.76%), stigmastan-3,5-diene(2.69%), 4h-benzo[f]pyrrolo[1,2-a][1,4]diaz epine, 4-(2-phenyl -propyl)-5,6- dihydro-(2.67%), vitamin e(2.51%), nonacosane(2.25%), tetratetracontane (2.25%), .beta.-tocopherol(2.04%), etc. So the benzene-alcohol extractives of bamboo leaves could be used as biomedicines.

摘要：
Bamboo is so easy to moulding that bamboo products haven't been high value added utilization. Therefore, the effect of wood extractives molecules on bamboo biology moulding was studied based on full-factor test. The result is: (1) The effect of tree species of wood extractives on bamboo biomass moulding was highly remarkable. The effect of treatment time on bamboo biology moulding was not remarkable.(2) The better anti-mold effects of wood extractives were Cassia siamea, Cunninghamia lanceolata, Eucalyptus urophydis, Populusdeltoides in turn. So this pointed out the direction for the development of the biologic mould inhibitor.
