遵照毛主席关于独立自主,自力更生。走自己发展科学技术道路的教导,我们从去年七月起采用了爆炸—冷拉和爆炸—挤压—冷拉制造多芯铌三锡复合超导线材新工艺。通过实验,用爆炸—冷拉法制得的线材规格和性能是:
Follow Chairman Mao’s principle of independence and self-reliance. Taking our own teaching on the path of science and technology, we started the new technology of manufacturing multi-core niobium-tin composite superconducting wire rod by explosion-cold drawing and explosion-extrusion-cold drawing since July last year. Through experiments, wire-rod specifications and properties obtained by explosion-cold-drawing are:
