<b>Abstract.</b> On the basis of experimental results a mathematical model for the non-stationary plasma with cylindrical symmetry was   proposed. In this model the plasma is stationary in the space, but each point of the torch participates simultaneously in two types of  temporal  pulsations:  a)  random  oscillations  following  a  Gaussian  distribution  and  b)  harmonic  oscillation.  In  this  model    the  distribution functions of the oscillations were found and radial intensities and temperature for the torch ICP (Inductively Coupled  Shapes) were calculated. The calculations were done for both the stationary and non-stationary cases. The effect of the pulsations in  the temperature was studied for different standard deviation values and amplitude of the temperature oscillations. The calculations  were made for the spectral line  Ar I 435.8 nm. The results show that the pulsations can affect the experimental measurements.
<b>Keywords.</b> Harmonic and random pulsations, model of the non-stationary  ICP plasma, temperature.
