Specificity of implementation of the principles of didacticism in the formation of metable knowledge in the course of informatics

The article analyzes the specifics of the application of traditional principles of didactics in the formation of metasubject knowledge in the course of Informatics and ICT. The analysis of the philosophical and social aspects of the development and use of technology shows that the basic component of the technical culture of a person along with specific technical knowledge becomes metasubject (metatechnical) as a system of generalized knowledge of the techno-sphere (its structure, content, patterns of functioning and develo.В статье анализируется специфика применения традиционных принципов дидактики в формировании метапредметного (метатехнического) знания в курсе информатики

PECULIARITIES OF THE DETERMINATION OF THE TEMPERATURE OF A FREELY BURNING ARC DISCHARGE FROM SELF-REVERSED RESONANCE SPECTRAL LINES OF ATOMS.

The results of calculations of the nonuniformity parameter M, used in determining the plasma temperature by Bartels' method, for self-reversed Na I 589. 0/589. 6 nm and Al I 308. 2 nm lines, emitted by an arc discharge burning freely in air, are presented. The calculations were performed for models of the positive column of the arc taking into account the ionization of atoms and the changes in the broadening of the lines in the radial direction. The effect of these factors in calculations of M are discussed

Spectroscopic diagnostics of a strongly inhomogeneous optically thick plasma. Part 2. Determination of atom concentration and variations of different physical values in the plasma cross-section using asymmetric self-reversed emission and absorption lines

The possibility of determining electron impact half-width and electron concentration, atom concentration and radial distributions of different physical values using the profiles of asymmetric self-reversed emission and absorption lines simultaneously and sequentially recorded over the plasma cross-section is examined. © 1995

Spectroscopic diagnostics of a strongly inhomogeneous optically thick plasma. Part 1. The formation of asymmetric self-reversed emission and absorption lines: determination of electron impact half-width and electron concentration

An analysis has been carried out of the profiles of asymmetrically self-reversed emission lines and of absorption lines using various models for inhomogeneous optically thick plasmas. Conditions of impulsing discharge, exploding wires, sparks, plasma jets, laser ablation of a target, etc. were considered. The possibility of determining electron impact half-width and electron concentration from the wings of asymmetrically self-reversed lines is considered. © 1995 Elsevier B.V. All rights reserved

Reaction-diffusion equations with spatially distributed hysteresis

The paper deals with reaction-diffusion equations involving a hysteretic discontinuity in the source term, which is defined at each spatial point. In particular, such problems describe chemical reactions and biological processes in which diffusive and nondiffusive substances interact according to hysteresis law. We find sufficient conditions that guarantee the existence and uniqueness of solutions as well as their continuous dependence on initial data.Comment: 30 pages, 14 figure
