FRAGMENTATION OF 20 STEEL PERLITE AT NONSTATIONARY DIFFUSION OF HYDROGEN [№ 6 ' 2007]
The phenomenon of 20 steel perlite observed at hydrogenation is described in this article. The method of electron microscopy for studying of metal defective structure transformation is used here. It is shown that the reason of the phenomenon is a relaxation of concentration hydrogenous microstress. Observed phenomenon of perlite fragmentation is accommodative process of repeated type and is observed at room temperature on the stage of disbalance diffusion of hydrogen.

COMPUTER MODEL OF THE EXPERIMENT [№ 1 ' 2007]
The methodic of experiment’s modeling with given dispersion of s2в repeatability of the research object response is worked out in this article. Computer experiment at wide range of s2в dispersion (from 200 till 1600) with ten parallel vectors of responses for every task allowing specifying some regularities determined exactness of experiment and regression polynomials, is conducted here.

SYNERGETIC CONCEPTION OF HYDROGEN DAMAGEABILITY OF METALS AND METALS (STAGES OF DEVELOPMENT AND PERSPECTIVES) [№ 1 ' 2006]
It is shown in the article that synergetic approach to the phenomenon of hydrogen materials fragility, originated at the contact with damp hydric sulphide gas, allowed getting original scientific results, working out theory of hydrogen fragility and solving actual practical tasks of diagnostics and increase of steel hydrogen resistance. A new concept of fractal energy hierarchy of structural material conditions, which has an applied and fundamental meaning and opens opportunities of energy parameterization of microstructures were introduced in physics of durability and materials science.

DISSIPATIVE TRANSFORMATIONS OF THIN STEEL`S MICROSTRUCTURES IN CONDITIONS HYDROGEN`S DIFFUSIVE TRANSFER [№ 10 ' 2005]
The article is devoted to researches of open system steel - hydrogen in conditions of diffusive transfer of an embedding impurity. The method of x-ray diffraction in situ is used during electrochemical hydrogenation of membranes and electronic microscopy for studying transformations of defective metal structure. Repeatability of processes of accumulation and discharge of micropressure with reorganization of defective structure in ОКР are established, migration of borders, formation of deformation relief, a substructure and porosity are also examined. The initial structure of steel influences on the kinetics of transformations.

AUTOMATED CALCULATION PIRSON`S CRITERION (MATHEMATICAL STATISTICS WITHOUT STATISTICAL TABLES) [№ 9 ' 2005]
The new design procedure of criterion of consent by Pirson is developed which allows to program these calculations easily. The table for values of integrated function of distribution both for negative, and for positive values of the standard of a random variable is constructed. The table is interpreted by a polynom of regress, which is entered into the program of calculation of criterion Pirson.

SOME COMPUTER EXPERIMENTS RESULTS WHICH MODEL DISTRIBUTION PARAMETERS ESTIMATE PROCEDURES [№ 7 ' 2004]
Software model of distribution parameters static estimate was worked out. It includes original equations for critical points t- and -distributions. Equations were got and their stochastic connection strength in accuracy of sample estimates Mx* and Dx*, samples volume and general dispersion was estimated. Efficiency qualitative indices of interval estimates were attained. They were formulated according to average data of several samples.

CALCULATING AND TRANSFORMING CHAINS FORMATION BY MEANS OF THE OPERATIONS DIFFERED FROM THE BASIC ONE. [№ 3 ' 2000]
The possibility of the functional transformers formation is considered on the basis of reflection functions device. The use of these functions gives the possibility to get chain structures of nosn-base composition of operational elements at the expense of changing the pole-zero diagram's form.
