Abstract: A graphic svstem of superconductor models developed by the aid of a basie IBM-PC microcomputer is presented. This system has been designed to store informarion on structures and properties of superconductors and related compounds discovered so far, to display and plot three dimensional crystallographic structure and coordination polyhedron structure, to search for oxide superconductive structural features to realize screen module design'. A suitc of interactive programs has been written to run on this system, and it fits especially for the study of high temperature oxide superconductive structure-property relationship. Meanwhile it is also expected to be useful in the guidance of discovering new high temperature superconluctors.
