摘要对两种无粘液体之间的球面界面的稳定性进行了理论检验。如果忽略表面张力，则发现界面是不稳定的还是稳定的，这取决于加速度是指向还是远离密度较大的液体。表面张力具有明显的稳定作用，并给出了破坏水中形成的空腔表面平衡所需的最小向外加速度的数值结果。这些结果被认为可能解释在水洞中测试的固定物体附近形成的空化气泡的行为。
ABSTRACT A theoretical examination is made of the stability of a spherical interface between two inviscid liquids accelerated radially from rest. If surface tension be neglected, it is found that the interface is unstable or stable according as the acceleration is directed towards or away from the liquid of greater density. Surface tension has a marked stabilizing effect, and numerical results are given for the minimum outward acceleration required to destroy the equilibrium of the surface of a cavity formed in water. These results are suggested as a possible explanation of the behaviour of cavitation bubbles seen to form near a fixed object under test in a water tunnel.
