摘要：

Different electron microscopy techniques were used to investigate the modulated structure of the compound Ca0.85CuO2. The orthorhombic basic structure agrees with recent literature based on neutron and X-ray diffraction evidence, but the modulated structure along (011)0 or (011)0 differs from it. The origin of the modulation is related to the calcium distribution within the CuO2 framework. The Ca-Ca separation is different from the Cu-Cu separation in the surrounding network; five calcium spacings correspond with six copper spacings. This explains the deviation of stoichiometry from the CaCuO2 composition.
