O nierównościach funkcyjnych jednej zmiennej
(1977)In this paper we shall deal with functional inequality (0.1). The main results are given in paragraph 2, where the algebraic structur of the family of solutions is given, and in paragraph 4, where a comparison theorem ... -
Wpływ składu procentowego na własności elektryczne roztworu stałego Pb/Zr[x]Ti[1-x]/O[3] dla 0,46 ≤ x ≤ 0,60
(1977)Temperature depedence of dielectric constant ε, electric conductivity, Seebeck's coefficient, were studied around the morphotropic boundary of the solution. On the ground of polaron theory of transport, charge carrier ... -
Przewodnictwo poeksplozyjnej plazmy metali Al, Sn, Pb, Ag, Cu, Au
(1977)Along with calculation results of relative electric conductivity of the plasmas as a function of temperature, an attempt at experimental verifying them within the temperature range of (10-30)10^3K, is reported. Within ... -
Wyznaczanie współczynnika efektywności termoelektrycznej niobianu sodu
(1977)To evaluate the possibilities of using sodium niobate in thermo-electric converters transforming heat energy into electric energy, the temperature changes of electric conductivity, of Seebeck coefficient and of the thermal ... -
Przyczyny niepowodzeń szkolnych w zakresie fizyki w klasach pierwszych szkół średnich
(1977)For most secondary school pupils physics proves to be a difficult subject. The reason for this is to be sought rather in the lack of proper didactic measures aiming at a well-graded mental development of the pupils than ... -
Zjawiska termoelektryczne w układzie $Pt-NaNbO_3-Pt$
(1977)Temperature changes of the electrical conductivity and of the Seebeck coefficient for the ceramics $NaNbO_3$, and $NaNbO_3$ + 0.2% mol $La_2O_3$, have been investigated. The obtained results have been used to define the ... -
Charakterystyki prądowo-napięciowe i przewodnictwo elektryczne niobianu sodu $NaNbO_3$
(1977)The temperature changes of electrical conductivity, as well as changes of the Seebeck coefficient and the electrical permeability of sodium niobate $NaNbO_3$, have been investigated. The obtained data were used to define ... -
New exsperiments on gas target spectroscopy. Atomic life-time measurements of some deuterium levels
(1977)The impact of heavy ions on various gaseous targets was observed within the energy range available in the Institute of Nuclear Physics, Cracow 200 keV accelerator. The ions passing through a gas target were recharged and ... -
Funkcja dydaktyczna klasyfikacji ornamentów
(1974)The paper presents a project of using the problem of defining and classifying symmetry groups of plane ornaments in teaching mathematics at various levels. Some of these problems are considered on examples concerning two ... -
Organizacja ćwiczeń z analizy matematycznej oparte na programowaniu indywidualnego przygotowania studenta do tych ćwiczeń
(1974)The article presents a report on investigation carried out by the author in the years 1967-1969. The purpose of the investigation was to elaborate a sort of work with the students of the first course of the mathematical ... -
Rozumienie implikacji przez uczniów liceum (fragment badań)
(1974)The paper presents part of larger investigation on "Formal and natural understanding by students the propositional connectors and quantifiers”. As the greatest difficulties met by students concern implication, which had ... -
Przyczynek do badań nad rozumieniem przez uczniów tekstu matematycznego
(1974)In the paper is presented an investigation and its results that concern understanding the contents of a mathematical statement by pupils of grammar schools (15-18 years old). An atempt has been undertaken to formulate ... -
Dydaktyczna rola skończonych i konkretnych modeli struktur matematycznych
(1974)In the article a finite and concrete model of a mathematical structure is called a system of sets and relations defined on those sets, being a model for the given structure and such that cardinal numbers of those sets ... -
Strategie rozwiązywania zadań matematycznych jako problem dydaktyki matematyki (fragment badań)
(1974)One of the main tasks of teaching mathematics is developing an ability to apply the acquired mathematical knowledge and skills for solving problems, as well as developing the student's creative attitude to problems on ...
