Abstract: A new generation of gun propellant, named Modified Single Base Propellant (MSBP), was successfully studied recently. The MSBP was prepared from single base propellant grain by impregnation with blasting oil, followed by deterring with deterrent in water medium. The function components in this propellant were nitroglycerine (NG) and polymer ester (NA). The concentration profiles of them were studied by Fourier Transform Infrared (FTIR) Microspectroscopy. The combustion performance of this propellant was investigated by means of closed-bomb tests and interior ballistic tests. It is found that the concentration profile of the function component is the key factor in MSBP. The static combustion performance and the characteristic of the interior ballistic are dependent on the concentration profile of function component.

Abstract: Pinus massoniana resources have been used as meidicine for a long time. Therefore, the 120°С volatiles of Pinus massoniana biomass were identified by TD-GC/MS. The main function components of Pinus massoniana Lamb biomass at 120°С were 1,4-methanoazulene, decahydro-4,8, 8-trimethyl-9-methylene-(36.04%), 1,4-methanoazulen-3-ol, decahydro-1,5,5,8a-tetramethyl-(13.95%), .alpha.-pinene(9.36%), 1,2,4-methenoazulene,decahydro-1,5,5,8a-tetramethyl-(5.95%), tricyclo[5.4.0.0(2,8)]undec-9-ene, 52,6,6,9-tetramethyl-(3.74%), caryophyllene oxide(2.9%), tricyclo[5.4.0.0(2,8)]undec-9-ene, 2,6,6,9-tetramethyl-(2.87%), bicyclo[2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)- (2.82%), p-menth-1-en-8-ol(1.92%), 1,3-benzodioxole, 5-(2-propenyl)- (1.4%), (+)-longicamphenylone(1.39%), eucalyptol(1.21%), etc. It showed that the volatiles of Pinus massoniana Lamb biomass at 120°С had some biohealth function.

Abstract: Black bamboo is becoming a major biomass in rooms. Therefore, the chemical components from black bamboo were identified by TD-GC/MS. The main function components of black bamboo biomass at 40°С were acetic acid(24.71%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(17.58%), 1h-indole-2-carboxylic acid,6-(4-ethoxyphenyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-, isopropyl ester(16.85%), cyclooctasiloxane, hexadecamethyl-(15.28%), cyclotrisiloxane, hexamethyl-(4%), etc. And the main function components at 50°С were acetic acid(40.39%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(24.47%), octasiloxane,1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(16.39%), bicyclo[2.2.1]heptan -2-one, 1,7,7- trimethyl-, (1s)- (3.73%), tricyclo[2.2.1.0(2,6)]heptane, 1,7-dimethyl-7-(4-methyl-3-pentenyl)- , (-)-(3.57%), etc. Black bamboo biomass was more healthy to human at 40°С than 60°С. So black bamboo biomass was fit to use in rooms.

Abstract: Phyllostachys heterocycla, who was considered to have biohealth function in folk, is becoming a major biomass in rooms. Therefore, the chemical components from Phyllostachys heterocycla were identified by TD-GC/MS at different temperature. The main function components of Phyllostachys heterocycla biomass at 40°С were 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester(21.32%), [1,1':3',1''-terphenyl]-2'-ol(9.16%), (2,3-diphenylcyclopropyl)methyl ph enyl sulfoxide, trans-(6.54%), cedrol(6.11%), bicyclo[2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)- (6.04%), 1,6-cyclodecadiene, 1-methyl-5-met hylene-8-(1-methylethyl)- (4.82%), 1-heptadecanamine(4.79%), propanedioic acid, methyl-, diethy l ester(4.36%), squalene(4.25%), etc. And the main function components at 60°С were1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester(14.02%), camphor(10.57%), [1,1':3',1''-terphenyl]-2'-ol(6.91%), pentanoic acid, 2-benzenmethanimin yl-5-guanidinyl-(5.68%), 1,6-cyclodecadiene, 1-methyl-5-methyl- (5.27%), cedrol(4.83%), 2-bromo-2,2-dichloroethylcarbamic acid, ethyl ester(4.56%), n-n-butylpropionamide(4.49%), bicyclo[3.1.1]heptane, 6,6-dimethy l-2-methylene-, (1s)- (4.12%), etc. Phyllostachys heterocycla biomass was more healthy to human at 40°С than 60°С. So Phyllostachys heterocycla biomass was fit to use after drying.
