The results of the computation indicate that the gradient of the gaseous medium and the velocity of gas atoms from the jet cannot cause detectable effects in experiments.
When measured in the medium temperature gradient exists, The average temperature of the measured temperature is the temperature of the components within the dielectric layer in the.
