4 measuring principle

1, a liquid drop on a solid surface, solid - liquid - gas-phase junction for gas - liquid interface tangent, the tangent and the solid-liquid deposit

It is the angle between the line between the contact angle. For a given system, the contact angle depends on the size of the three-phase interface (liquid/gas, solid/gas and liquid/solid) Room
