摘要：

W-1000 orthoconic antiferroelectric liquid crystal eutectic mixture was prepared in Military University of Technology. This mixture is probably the broadest antiferroelectric mixture, ever prepared. Precise dielectric measurements were performed in a broad temperature range. Some parameters of detected modes and their temperature characteristics are found. It seems that in different temperature regions of orthoconic antiferroelectric liquid crystal different numbers of modes should be anticipated to fit experimental results. Results are discussed with respect to the theoretical model.
