摘要：

The phase transitions, effective molecular polarisibilites, molar volumes and order parameters of hexoxy and heptoxy cyanobiphenyl (6OCB and 7OCB) and the eutectic mixture E-6O7, composed of hexoxy and heptoxy cyanobiphenyls (41.5:58.5), were calculated and compared using accurate optical and density data measured at several temperatures. The order parameters calculated using the different methods of Vuks, Neugebauer, Saupe-Maier and Palffy-Muhoray are nearly the same for the liquid crystals considered in the present study.
