The free energy of activation of bimolecular radical substitution reactions can be calculated from the increment values of the transition state. The latter are calculated, starting from the general principle of the additivity of thermodynamic functions in the transition state. The values of the reaction rate constants calculated from them are in satisfactory agreement with experimental data. The values of the free energy of activation can be used as characteristics of the relative activity of the radicals and molecules in bimolecular substitution reactions. 相似文献

The dynamics of axisymmetric detonation waves in a round pipe containing an annular near-wall bubble layer with a combustible gaseous mixture are studied. The situations in which within the annular layer there are a pure liquid or a bubbly mixture with an inert (unexplosive) gas are considered. 相似文献

We prove the following: 1) if E is a B-convex Banach lattice, the space l(E) is a Grothendieck space; 2) if the space E has the p-Banach-Saks property for some p>1, the space c0(E) also has this property. It is shown by examples that these conditions are close to being necessary. These results are applied to study the geometric structure of limits of symmetric spaces.Translated fromMatematichni Metodi ta Fiziko-Mekhanichni Polya, Vol. 40, No. 3, 1997, pp. 39–44. 相似文献

In the case of Lipschitz extremals of vectorial variational problems, an important class of strong variations originates from
smooth deformations of the corresponding non-smooth graphs. These seemingly singular variations, which can be viewed as combinations
of weak inner and outer variations, produce directions of differentiability of the functional and lead to singularity-centered
necessary conditions on strong local minima: an equality, arising from stationarity, and an inequality, implying configurational
stability of the singularity set. To illustrate the underlying coupling between inner and outer variations, we study in detail
the case of smooth surfaces of gradient discontinuity representing, for instance, martensitic phase boundaries in non-linear
elasticity. 相似文献
