Dwustanowy regulator temperatury z korekcją mocy wyjściowej
(1980)A concept of improving the transient process in an on-off temperature control unit. The power fed to the heating element is gradually increased or decreased in response to a sawtooth waveform from a generator controlled ... -
Impulsowy, tyrystorowy regulator temperatury
(1980)The principle of operation of a silicon controlled rectifying regulator of temperature, driven by impulses, is discussed. The main design data of a prototype and its parameters are given. -
Prądy ograniczone ładunkiem przestrzennym dla $(Pb_{0,95}Sr_{0,05})$ $(Zr_{0,53}Ti_{0,47})O_3$ z domieszkami 3% mol $PbO$, 1% mol $La_2O_3$, 1% mol $Nb_2O_5$
(1980)The influence of the admixture of 3% $PbO$, 1% $La_2O_3$ and 1% $Nb_2O_5$ on the electric properties (electric permeability, electric conductivity, Seebeck coeficient and current - voltage, current - time characteristics) ... -
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 - ...
