摘要：

Data are reported which show that the liquid-condensed-to-liquid-expanded (LC/LE) phase transitions of a pentadecanoic acid monolayer and a dipalmitoylphosphatidylcholine monolayer are first order. In particular we measured a zero slope of the pi-A isotherm in the LC/LE transition region using a continuous compression method. The data were obtained by using a very careful experimental protocol. We also examined the state of equilibrium or stability of the monolayer system.
