By developing the local resonat X-ray scattering technique using a synchrotron X-ray microbeam, novel sub-phases appearing in the chiral smectic liquid crystals were studies and new information about the inter molecular interaction and the phase transition mechanism has been obtained. A sub-phase with a six-layer periodicity which appeared between the ferroelectric and the antiferroelectric phases was found in the chiral smectic liquid crystal mixture and it agreeed well with the theoretical model. During the electric field induced phase transition, a 12-layer periodicity phase appeared. An x-ray intensity analysis suggested that the molecular configuration realized in this phase was the new intermediate phase between the adjacent phases.

通过发展同步辐射X射线微束局域共振X射线散射技术，研究了手性近晶液晶中出现的新亚相，获得了关于分子间相互作用和相变机理的新信息。在手性近晶液晶混合物中发现了介于铁电相和反铁电相之间的具有六层周期的亚相，与理论模型吻合较好。在电场诱导相变过程中，出现了12层周期性相。X射线强度分析表明，在该相中实现的分子构型是相邻相之间的新中间相。
