摘要： A method of manufacturing glass rod for optical waveguides is proposed. In this method, several gaseous mixtures or powdery mixtures of materials for glass forming are reacted at a high temperature and deposited on the top or end of a rotating glass rod which is initially deposited on a rotating base plate and grown in the form of a rod of a fixed powdery or vitreous state. It is possible to obtain the glass rod having a predetermined radial distribution of index of refraction.

摘要： A superconducting ceramic wire is prepared from a superconducting ceramic-forming oxide composition by melting, the composition and quenching the melt to form a dense glass, which is soften and wire-drawn in a furnace. The resulting wire is heat-treated to form crystals and made into a superconducting ceramic wire. The wire has a flexibility and remarkable superconductivity which can further be improved by applying pressure to be made more dense and repeating the heat-treatment.
