【摘要】 通过对三个典型实例的分析，归纳出液滴表面呈球面的条件是液滴表面内外压强差处处相等。用热力学理论阐明了：在这种条件下，体积一定的液滴表面必呈球面。更多还原

【Abstract】 The condition for the surface of a liquid drop forming spherical surface was induced by analysing three typical examples. It is that the difference between intra-surfacepressure and extra-surface pressure remains equal all over the surface.Jt was expounded byusing thermodynamics that the surface of a liquid drop with invariable volume must formspherical surface under this condition.更多还原
