Abstract. The work shows that the laws of dynamics describe the basis of the vision of the universe. The formulation of Planck's constant dependence on time, which we called the evolutionary index, is given. The law of evolution, the boundaries of the distribution of parametric criteria, the uncertainty principle of Werner Heisenberg on all evolution are determined. The ratio of synchronism and symmetry of parametric criterior`s of the Universe is considered.
Key words: parametric criteria, evolutionary index, Heisenberg uncertainty.
Summary. The paper deals with a problem with initial conditions for a beam equation with embedded ends. The problem was solved in two ways: as a sum of the Fourier series in the system of eigenfunctions of a one-dimensional spectral problem, and using finite-difference approximations, a numerical solution was obtained. The quantitative coincidence of the results of numerical and analytical calculations of beam deformation is obtained.
Key words: oscillations of a beam, the Euler equation, the initial-boundary conditions.

Summary: This work is dedicated to the study of almost everywhere solution of one-dimensional mixed problem for one class of semi-linear fourth order equations. Conception of almost everywhere solution for mixed problem under consideration is introduced. In the conventional method, i.e. multiplication of the equation on the right function and subsequent relevant term by term integration (including some integration by parts), a theorem on a priori estimation of the solution almost everywhere under consideration of the mixed problem.
Key words: semi-linear equation, mixed problem, almost everywhere solution, a priori estimate.

Annotation: The purpose of work is development of the computer program of design of cluster structure of fusions of simple metals with the crystalline grate of type of body centered cubic (BCC) for comparison with experimental data of X - raying. For this purpose methods are worked out:
1. Calculation of coordination numbers on a cluster for their subsequent middling according to sample and comparison (approximations) with the experimental radial function of distribution of atoms (RFDA). Thus the choice of form of cluster was carried out in accordance with principle of Curie-Woulf and Brave - about a minimum of superficial energy of crystal, being in an equilibrium with the liquid, and that a crystal is limited to the atomic planes with the maximal closeness of atoms. For BCC of grate clusters correspond them in a form: bipyramids, prisms, threepyramids, moreover first from named corresponds most ratio of volume toward the area of surface, i.e. she is most credible.
2. For the forms of clusters indicated higher the discrete functions of form and their continuous analogues were certain in different directions of translations.
3. To the finding functions were certain Fourier- characters (intensities) for description of types of diffraction peaks for the case of bipyramids.
The use of finding dependences is work out the computer program of design of cluster structure, which consisted in approximation of experimental data of X - raying researches of fusions of alkaline metals a theoretical model.The results of approximation it is been: determination of mean value of coordination number, middle interatomic distance, optimal clustersize, middle distance between clusters. Calculations is executed for many alkaline metals in the wide interval of temperatures. Data for a rubidium at the temperature of 513К have next values: middle interatomic distance - 5,755 Å, optimal clustersize - 12,756 Å, middle coordination number - 1,325, middle c distance between clusters - 0,518 Å.
Key word: co-ordinating numbers, optimal clustersize.
