The dynamical local lattice distortion in the CuO 2 plane of the cuprate high‐temperature superconductors is investigated with the numerical diagonalization study for finite clusters of t ‐ J model. It is found that the in‐plane vibrations of the oxygens play an important role in the formation of some static orders like CDW and SDW through the polaronic self localization effect. The 1/8 problem is also discussed based on the present result.
