摘要：

For aqueous solutions containing vesicles formed by sodium di-n-dodecylphosphate, the gel-liquid-crystal transition occurs near 35-degrees-C at the temperature T(m). When ethanol is added, T(m) decreases. When sodium chloride is added, T(m) shifts to higher temperatures whereas very complex scans with several transitions are recorded when calcium chloride is added. The complexities are attributed to the binding of Ca2+ ions by phosphate groups at the vesicle surface.
