摘要：

The guiding principles to reduce superconducting-anisotropy were derived for high-T-c cuprate superconductors. Based on the principles, we have attained the least superconducting-anisotropy gamma=1.6 for a Cu-based CuBa2Ca3Cu4O12-gamma (Cu-1234) superconductor. Further lower superconducting-anisotropy has been proposed for Cu-1245 (gamma=1.3) and Cu-1256 (gamma congruent to 1.0) Cu-based superconductors.
