"Two new analytical models M3 and M4 describing processes with high volume compression and/or expansion ratios (occuring e.g. in the cavitation bubbles) and supposing the heat transfer is proportional to temperature difference between the ideal gas and surroundings are presented. Theirs simplicity is comparable with the one of the polytropic process (Mp). Properties and results of calculations of all models Mp, M3 and M4 are discussed. At the volume ratios 10(3) the results of M3 and Mp models differ in tenths of percent, the ones of the model M4 of about 30% more than of the model M3. The model M4 seems to be a little more suitable then the model M3."@en . . "Slovensk\u00E1 po\u013Enohospod\u00E1rska univerzita v Nitre" . "Bayer, Zden\u011Bk" . . .
