摘要：
The basic parameters, describing the polarization and electrooptical properties of mixtures, composed from lamellar matrix and dopants of chiral molecules, are measured. The model was proposed assuming the inclination of chiral molecules even in orthogonal phase. According to this assumption the essential Fluctuations of biaxial order in vicinity of the Ferroelectric phase transition temperature take place. The induced biaxiality noticeably changes the temperature behaviour of basic characteristics of ferroelectric liquid crystal, for instance the polarization to tilt ratio and response times in this transient range, where some characteristics possess very sharp dependences on temperature and on external electric field.
