Abstract: This paper describes the measurements of the contact angles of wate-glass-oil and water-glass-benzene which is hard with optical ways with nuclear magnetic resonance imaging technique. The result is curve-fitted and the angles are calculated by the Matlab. This is the first time that the measurement of contact angles with MRI is introduced, it may lead to further applications of liquid-solid-liquid and gas-solid-liquid contact angles measurements.

Key words: nuclear magnetic resonance imaging （MRI）, liquid-solid-liquid, weighting imaging, contactangles
