In order to establish the necessary condition for such cavitation-erosion-tests in vibratory-erosion test-apparatus, the cavitation-nuclei size-distribution and the relative air content rate of test water were carefully measured with respect to test time, by means of a Coulter-counter and a van Slyke apparatus respectively. It is worth noticing in the vibratory cavitation apparatus that the exponent and the volume concentration characterizing the nuclei-distributions do not fluctuate with test time in the equilibrium period, which reaches after 60 min. And that the air-content-rate first decreases monotonously with the time, then it reaches a definite equilibrium value after 40 min, which is much longer than the ASTM recommended value.
