The second order rate constants of DMS oxidation by H 2O 2 rang from 2.21×10 -2 ￣4.90×10 -2 L·mol -1 ·S -1 . The oxidation reaction rate is speeded up in the presence of Hg 2+ , which is especially apparent in artificial seawater medium.
The results show that the reaction is the second order kinetics at 303—318 K. The kinetic equation obtained is r=k[ZnCl_(2)/Clay-SA_(01)]~(0.8)[C_(6)H_(6)][C_(6)H_(5)CH_(2)Cl],with an apparent activation energy 88.6 kJ/mol.
thi reaction of the S_2O_3~(2-)+3I~-=2SO_4~(2-)+I_3~- is studied in this paper, the experimental results showed that this reaction is a second order reaction the possible reaction mechanism and its correctness are discussed
We got such data by experiment in the anaerobic and two-stage alternation intermission aerobic technology conditions: Y(microbial growth coefficient)=(0.200), K_d(attenuation coefficient)=(0.055 d~(-1)), K(microbial maximum specific growth rate)=(3.12 d~(-1)), K_s(saturation constant)=(38.3 mg/L);
Behavior near the boundary of positive solutions of second order parabolic equations
We state a localization principle for expansions in eigenfunctions of a self-adjoint second order elliptic operator and we prove an equiconvergence result between eigenfunction expansions and trigonometric expansions.
We also obtain a way of constructing an arbitrary number of non-Gaussian continuous time processes whose second order properties are the same as those of fractional Brownian motion.
The line search functions used are Han's nondifferentiable penalty functions with a second order penalty term.
Finally, we prove the global convergence and the local second order convergence of the algorithm.
In the second example, we obtain a proof of the Chalyh-Veselov conjecture that the Calogero-Moser system with integer parameter is algebraically integrable, using the results of Felder and Varchenko.
A local-global principle is proved by the second named author in the adjacent paper of this volume.
In the second part we apply this method to obtain pseudo-Riemannian homogeneous manifolds with real Killing spinors.
We derive two consequences: the first is a new proof of Lusztig's description of the intersection cohomology of nilpotent orbit closures for GLn, and the second is an analogous description for GL2n/Sp2n.
The second part consists in the normalization of the Burkhardt dual.
