The experimental spectra of 〈pt〉 versus the average pseudorapidity multiplicity density, 〈Ncoll〉, and 〈Npart〉 dependencies of the identified charged particles at midrapidity in Au+Au and Pb+Pb collisions at RHIC and LHC in (snn)1/2 = 62-5020GeV energy range are described well with the proposed simple power model function. The degree of flattening of 〈pt〉 of the charged pions and kaons, protons and antiprotons in the analyzed heavy-ion collisions at RHIC and LHC in (snn)1/2 = 62-5020GeV energy range are investigated analyzing the dependencies of the obtained exponent parameter α of the simple power model function on the particle species and collision energy (snn)1/2. The coincidence of the parameter α for pions and kaons in Pb+Pb collisions at (snn)1/2 = 5.02TeV, reflecting practically identical shapes of 〈pt〉 versus the average pseudorapidity multiplicity density, 〈Ncoll〉, and 〈Npart〉 spectra for pions and kaons in these collisions, is obtained. This important result is interpreted as due to creation of the highly thermalized QGP, where the difference between u, d and s flavors practically disappears, resulting in similar mechanisms of production of pions and kaons in Pb+Pb collisions at (snn)1/2 = 5.02TeV.
