该假说讨论了空化核存在于气泡中。由于表面张力的作用，小气泡会在很短的时间内溶解。当气泡大于5× 10−3cm，或者液体过饱和时，气泡可能会持续更长时间甚至稳定，但此时不存在空化阈值。该假说认为，原子核是非常小的气泡，由一层有机外壳稳定下来，它可以机械地防止扩散造成的气体损失。当皮肤破裂时就会发生空化，而阈值由薄膜的断裂强度和气泡的大小决定。
< jats: p> The hypothesis discussed that the cavitation nuclei consist in gas bubbles. Due to surface tension, small bubbles would dissolve in a very short time. If the bubbles are larger than 5× 10− 3 cm, or if the liquid is supersaturated, they may last longer or even be stable, but then no cavitation threshold exists.< jats: p> The hypothesis expressed that the nuclei are very small bubbles, stabilized by an organic skin, which mechanically prevents loss of gas by diffusion. The cavitation occurs when the skin breaks and the threshold is determined by the breaking strength of the film and the size of the bubble.
