3 terminology and units of measurement

3.1 interface interface Usually refers to the transition zone thickness of about several elements of the two-phase contact, such as the one for the gas phase, this interface is often called Surface. 3.2 interfacial tension interfacialtension Along immiscible two-phase (liquid - solid, liquid - liquid, liquid - gas) acting on the interface between the vertical surface of the liquid per unit length Surface contractile force. Units of mN/m.

4 Overview

4.1 Structure Tension measured by the tension device, test bench, controlled mobile device and platinum loop, stirrup-shaped ring or platinum plates. According to the structure can be divided into mechanical and electronic tension meter tension meter types. 4.2 Principle One method of interfacial tension of two ways platinum loop method or platinum plate can be measured. 4.2.1 platinum loop method DuNouy known as the Tour de France, the bail law, from the Tour de France. It is measured as follows. ......
