A detailed study of the pressure oscillation induced by the film boiling of He Ⅱ is presented. The film boiling state and the stability of the vapour film are determined by the goveing parameter (i.e. the immersion depth). It is found that the power density spectrum of the pressure oscillation induced by the film boiling displays the 1/fα-behaviour. The exponent α was found to be within the range from one to two, which indicates the existence of self-organized criticality in the film boiling of He Ⅱ.
