Using numerical experiment one-dimensional unsteady processes of heterogeneous combustion in porous object under free convection in horizontal case have been investigated and compared with vertical case. It is shown that in the case of the horizontal porous object the oxidizer supply, which is the result of natural convection, is not sufficient for the appearance of stable wave of heterogeneous combustion. In contrast to the vertical position of the object, there are no long-lived combustion waves in the horizontal case, which completely burns down the solid combustible material. When the ignition zone is on the border of the object, the combustion wave near the vicinity of the boundary burns the oxygen and becomes extinct. When the ignition zone is in the center of the porous object, two combustion waves arise which may move very slowly, burn oxygen and become extinct.

One important way to control the technical condition of the high-voltage power equipment element is the monitoring and interpretation of electromagnetic radiation. Analysis of the spectra of emitted high-voltage equipment EMR provides information on which determines the intensity discharge processes occurring in insulation and other structural elements of high voltage equipment under the operating voltage without interfering with the process.

The study of optical properties of AlO, SiO, TiO, and Zn O nanoparticles in weak optical fields is presented. We found that some nanoparticles have unique optical nonlinearity: The values of portions to nanoparticle refractive index and absorption coefficient increase to maxima, and then decrease to zero when the radiation intensity changes from 1 to 500 W/cm2. We estimated electron energy structures of nanoparticles and experimentally determined that such nonlinearity is directly related to peculiarities of the energy structure. We obtained a good fitting of theoretical results to the experimental ones（e.g. absorbance spectra of nanoparticles;the dependence of nanoparticle refractive index and absorption coefficient on radiation intensity）.

In this paper we propose an original functional method which allows us to determine the effect of different deviations of nano-object shape on quantum characteristics of particles localized inside the nano-object. This method is ideologically similar to the perturbation theory, but the perturbation of the surface shape, rather than potential, is used. The results of analysis the quantumsize states of particles inside the nano-object with deformed sphere shape showed that the probability density of particle location is more sensitive to shape perturbations than surface energy spectrum and quantum states density are.
