Summary Almost sure convergence theorems are proved for Cesaro averages of continous functions in the case of the symmetric exclsion
processes in dimension d≧3. For the occupation time of a single site the same result is proved in all dimensions.

Central limit theorem for additive functionals of reversible Markov processes and applications to simple exclusions 总被引:3,自引:0,他引:3
We prove a functional central limit theorem for additive functionals of stationary reversible ergodic Markov chains under virtually no assumptions other than the necessary ones. We use these results to study the asymptotic behavior of a tagged particle in an infinite particle system performing simple excluded random walk.Supported by NSF Grant MCS-8301364, ONR Contract N00014-81-K-0012 and a Fellowship from John S.

The Wiener-Hopf method is used to find a solution to a symmetric problem that gives a criterion for the onset of growth of
long shear cracks emanating from a corner point on the boundary of a hole and filled with a plastic material

Reactions of dimethyl ether (DME) over γ-Al2O3 at 250°C have been investigated in a flow catalytic reactor. The main products of the interaction between DME and alumina are methanol and water. Heat evolution is observed as DME is passed over alumina, and replacing DME with nitrogen gives way to heat absorption. Calcination of alumina before the reaction considerably strengthens the exotherm, which is due to DME adsorption, while the endotherm is due to the desorption of weakly bound DME. The role of the hydroxyl groups of γ-Al2O3 in methanol and water formation has been elucidated. Treating alumina with water vapor after bringing it into contact with DME completely restores the hydroxyl cover and replaces strongly adsorbed DME with hydroxyl groups. 相似文献

The peculiarities of methanol transformation on the surface of perfluorinated copolymer, fluoroplastic, containing sulfo groups
were studied. At temperatures of 70–120°C, the polymer was established to have high initial activity during the conversion
of methanol into dimethyl ether; this reaction was, however, accompanied by strong water sorption that leads to a rapid drop
in the activity. The sorption/desorption processes were characterized by temperature effects such as heating during sorption
and cooling during desorption. The structure of the polymer in the salt (sodium cations) and acid (hydrolyzed polymer) forms
was studied by IR spectroscopy. H3O+SO3− ionic pairs were found to be present in the acid form. 相似文献
