固体表面球冠状液滴开尔文方程推导

Derivation of Kelvin equation for spherical crown liquid droplet lied on solid surface

推导了固体表面球冠状液滴与气体两相平衡的热力学判据.并依据杨氏公式及球冠几何计算公式,直接证明了对于附着在固体表面的球冠状液滴的平衡气体压强与固体壁面的材质无关.证明过程物理模型清晰,热力学意义明确.

This paper deduces the thermodynamic criterion of two phase balance between spherical crown liquid droplet and gas. The gas pressure balanced with spherical crown liquid droplet is unrelated to solid material in terms of Young＇s formula and formula of spherical geometry. The process of proof has clear physical model and thermody- namlc meaning
