Wpływ defektów tlenowych na zmiany temperaturowe przewodnictwa elektrycznego niestechiometrycznego niobianu sodu
(1984)Measurements of electrical conductivity of nonstoichiometric $NaNbO_3$ were made in the air atmosphere under normal and reduced pressure. It was stated that the value of electrical conductivity is strongly effected by ... -
Elektryczne i fotoelektryczne własności monokryształów $PbMg_{1/3}Nb_{2/3}O_3$ w niskich temperaturach
(1984)Electric and fotoelectric properties of monocrystals $PbMg_{1/3}Nb_{2/3}O_3$ in low temperatures are discussed. It is found that in the region of low temperatures electric properties of $PbMg_{1/3}Nb_{2/3}O_3$ are to large ... -
Wpływ domieszek $La_2O_3$ na własności elektryczne niobianu sodu $NaNbO_3$
(1984)The temperature changes of electric conductivity and of electric permittivity were investigated for the $NaNbO_3$ and $NaNbO_3$ + /0,1%, 0,2%, 0,25%, 0,3%, 0,4%, 0,5% and 1% mol $La_2O_3$/ ceramics. Obtained data were ... -
Otrzymywanie ferroelektrycznych ceramik o dużej gęstości
(1984)The method of hot pressing permits to obtain the ceramics of high density. It consist in simulate neons application of high temperature and pressure on charge made of pressed powder. The authors elaborated several devices ... -
Magnetyczne związki o strukturze ilmenitu : konstrukcja sieci prostej i odwrotnej
(1984)This paper deals with the structural data of all known magnetic compounds of ilmenite structure. The parameters of the crystallographic and magnetic rhombohedral cells, also for the reciprocal lattice are compared. The ... -

(1984)The magnetic shielding of [23]Na nuclei in NaNO[3], NaClO[3], NaBrO[3] was investigated theoretically and experimentally. The theory of the magnetic shielding based on the perturbation theory approach of Ramsey was used. ... -
Potencjały cylindrycznie i sferycznie niezmienniczych pól Yanga-Millsa
(1984)A general definition of symmetries of gauge fields is proposed and a method developed for constructing symmetric fields for an arbitrary gauge group. This method was used to find SU(2) (and SU(3)) Yang-Mills fields ... -
Rola fizyki teoretycznej w kształceniu nauczycieli fizyki
(1984)Some thoughts concerning the role of theoretical physics in educating the teachers of physics are presented by the authors of the paper. They evaluate the importance of theoretical physics in the university syllabi and ... -
Poprawka relatywistyczna do przekroju czynnego na rozpraszanie neutronów przez jon paramagnetyczny
(1984)The relativistic correction is derived for the general formula of the cross section for magnetic scattering of thermal neutrons by paramagnetic ion, obtained by Lovesey for nonrelativistic approximation.
