表面张力这一术语通常用于空气-液体界面，而界面张力用于其它界面，如液体-液体界面或液体-固体界面。
The term surface tension is usually applied to an air-liquid interface, and interfacial tension to other interfaces such as liquid-liquid or liquid-solid.
它可以减少液体、固体和气体界面间的表面或界面张力，容易在水或其他液体中混合或扩散，因而广泛应用于环境保护等领域。
It can reduce the surface tension between liquid, solid or gas. Because of being mixed or diffused easily in liquid, it has been widely used in environmental protection.
