摘要：

The structure of frustrated smectic phases exhibited by binary mixtures of 4-n-octyloxyphenyl-4'-cyanobenzoyloxybenzoate (DB8OCN) and 4-n-octyloxybenzoate-4'-cyanoazobenzene (8OBCAB) have been studied by high-resolution x-ray diffraction. This system was previously reported to exhibit three incommensurate smectic-A phases. These incommensurate smectic A(i1) A(i2), and the soliton A(i2) phases are found to be coexistences of A(d) and A1; A(d) and A2; and A(d), A1, and A2 phases, respectively. As of now, there are no known incommensurate smectic-A phases.
