The solubility parameter differences between the prepolymer and the main components(NG,DEGDN and NC) of double base propellant are less than 4×10-3 J0.5m-1.5,showing that P(E-CO-T)-N100 system has good compatibility with the later.
The H2/CO ratio of equilibrium composition was mainly deter- mined by the H_2O/CO_2 ratio of feed composition,but it had little relation to oxygen content.
CATALYTIC REACTION PRINCIPLES AND CATALYSTS FOR COMPLETE CONVERSION OF C_5 FRACTION INTO ISOPENTENE Ⅱ. PRODUCTION OF ISOPENTENE BASED ON DEHYDROGENATION OF ISOPENTANE
The tribological behavior of different fraction diesel separated with distillation method was investigated and the lubricating performance of different polar diesel separated with chromatographic column separation method was evaluated.
Semi-invariants of quivers can be constructed by taking admissible partial polarizations of the determinant of matrices containing sums of matrix components of the representation and the identity matrix as blocks.
Finally the cubic surfaces of each component ofQ are studied in details by determining their stabilizers, their rational representations and whether they can be expressed as the determinant of a 3×3 matrix of linear forms.
This underlying group H1(X, T \bar{X}) can be described as a generalized Prym variety, whose connected component is either an abelian variety or a degenerate abelian variety.
We study the composition of the functor from the category of modules over the Lie algebra $\mathfrak{gl}_m$ to the category of modules over the degenerate affine Hecke algebra of GLN introduced by I.
We also establish a connection between the composition of the functors, and the "centralizer construction" of the Yangian ${\rm Y}(\mathfrak{gl}_n)$ discovered by G.
For Fourier-bandlimited symbols, we derive the expected formulae for composition and commutators and construct an orthonormal basis of common approximate eigenvectors that could be used to study spectral theory.

The following structure has been determined for the repeating unit: →6)-α-D-Glcp-(1→ This fraction exhibited significant macrophage activity through the release of nitric oxide
In the present study, the effect of picroliv, an irridoid glycosidic fraction of Picrorhiza kurroa, on the above said parameters of these alcoholic rats was studied.
Because of the existence of nanopores, the dielectric constant of PI films decreased by a wide margin and was less than 2.0 at a PU mass fraction of 20%.
The percolation thresholds of PS/PPy and Zn-SPS/PPy composites were 6.2% and 2.7% of the volume fraction of PPy, respectively, much lower than the theoretically predicted value of 16%.
