There is adduced example of modern comparative analysis of the state and motion parameters in free supersonic gas jet and at its interaction with diverging part of supersonic nozzle. It is showed, that in both these cases sonic velocity M = 1 is attained in expanding part of the jet but not in the converging nozzle neck. It is adduced method for physically adequate reproduction of the state and motion parameters in supersonic gas stream by means of traditional tables of gas dynamic functions
