英文摘要	Raman spectra of the unreduced and reduced barium titanate(bt) and potassium tantalate niobate(ktn) are examined. the fano asymmetric cut-off is on the low-energy sides at raman features at 196 and 474 cm(-1) in bt and at 210 cm(-1) in ktn, which indicates nonlinear interference with a positive coupling coefficient. the origin of their lineshape distortion and sign of the coupling coefficients are discussed owing to nonlinear interaction between one-and two-phonon states. the results are well compared with those in distorted perovskite oxide y- and bi-system superconductors.
