摘要：
The surface tension of normal liquid alkanes (chain lengths between 15 and 18 carbon atoms) has been measured as a function of temperature. In all cases the tension exhibits a well-defined change in behavior at a temperature close to, but distinct from, the melting point. The phenomena are consistent with a surface-induced phase transition in which the conformational degrees of freedom of molecules close to the surface are inhibited. Various properties of the transition vary smoothly with alkane chain length.
