Określenie możliwych konfiguracji spinowych w sieci spinelowej NiFeAlO[4]
(1980)This article contains the results of theoretical computations which serve a model of the ordering of magnetic moments in the NiFeAlO[4] spinel lattice on the base of molecular field theory assuming the crystal anisotropy. ... -
Niejednorodne transformacje symplektyczne w mechanice klasycznej i kwantowej
(1980)The connection between quantum-mechanical unitary transtormations and canonical transformations of classical mechanics is discussed in the special case of nonhomogeneous symplectic transformations. The discussion is based ... -
Własności elektryczne roztworu stałego PLZT
(1980)The temperature dependences of the electric permeability, electric conductivity. Seebeck coefficient and current - voltage characteristics for the solid solution (Pb[0,92]La[0,08]) (Zr[0,65]Ti[0,55) O[3], were studied. ... -
Wpływ redukcji tlenowej na zmiany temperaturowe przewodnictwa elektrycznego niobanu sodu
(1980)A design of a new quartz thermostate is described. It controls: 1) The temperature of the sample from ambient temperature to 1270 K, 2) The pressure of the atmospheric air or other gases within the range from $133,3°10^{-6}$ ... -
Koncepcja wprowadzenia funkcji rozkładu Maxwella w kursie fizyki ogólnej
(1980)In the conventional teaching of the Maxwell distribution law to the beginners, the calculus of variation and Lagrange's method of undetermined multipliers are used. As a result the beginner must frequently employ mathematics ... -
Porównanie algebraicznej i geometrycznej metody kwantowania dla oscylatora harmonicznego
(1980)Two descriptions of the energy levels and states of a quantum harmonic oscillator are discussed: the method using its symmetry group SU/n/ and the "geometric quantization" method. The operator creating arbitrary n,l,m - ... -
Badanie stanów rozproszeniowych i związanych atomu wodoru metodami geometryczno-grupowymi
(1980)Bound and scattering states ot the hydrogen atom are described using Lie algebras of groups 0/4/, 0/3,1/, 0/4,1/. Comparison with the results of the geometric quantization is made. -
Charakterystyki prądowo-czasowe w układzie $metal-NaNbO_3-metal$
(1980)The temperature changes of current - voltage and current - time characteristics having been investigated, data are used to define the type of conductivity and to determine the activation energy of the charge carriers. ... -
Wyniki wstępnych badań nad przebiegiem procesu myślenia uczniów podczas rozwiązywania problemów fizycznych
(1980)Results of the preliminary investigations on ways of thinking processes in solving physical problems are presented. The investigations were organized in high school classes for groups of students regarded by teachers as ... -
