The temperature function for the integral emissivity of certain materials below 300° KSpringer Science and Business Media LLC - Tập 14 - Trang 294-297 - 1968
R. S. Mikhal'chenko, A. G. Gerzhin, N. P. Pershin
We present the method for and the results from an experimental investigation into the temperature function of the integral emissivity for certain materials used in low-temperature multilayer vacuum insulation. We study the effect of fiberglas filler materials on radiative heat transfer.

The blood of healthy children aged 2–14 was investigated. No differences between the aggregation parameters depending on the sex were revealed. In the children under the age of five, the amplitude of aggregation and the time of formation of linear aggregates were reliably lower and the strength of the largest of them and their total strength were decreased in comparison with the other age groups. ...... hiện toàn bộ
Reduction of methodological errors in determining the temperature of metals by two-color pyrometersSpringer Science and Business Media LLC - Tập 79 - Trang 768-772 - 2006
A. G. Sen’kov, V. A. Firago
Two-color methods of optical control of the thermodynamic temperature of metals subjected to thermal treatment are analyzed. A technique for taking into account the nonmonochromaticity of the photoreception path is suggested and an analysis of methodological errors of two-color pyrometers with wide spectral ranges is performed by numerical simulation.
Transport phenomena in a nonequilibrium, partially ionized gas in a magnetic fieldSpringer Science and Business Media LLC - Tập 26 - Trang 641-652 - 1974

A small-parameter method in which the gas and electron temperatures can be different is used to solve the Boltzmann equation. The zeroth-approximation solutions are Maxwellian with different temperatures Te and Ts. Transition to the BGK formalism on the basis of an extremely crude estimate of the frequency of electron collisions leads to numerical results which agree well with the available data. ...... hiện toàn bộ
