同志们: 对这次大会的召开,我表示热烈的祝贺,并预祝大会取得圆满成功。借今天的机会,我谈谈“六五”期间,特别是1983年第七届技术交流会以来,我国轻合金加工工业的发展概况。大家知道,材料是四化建设的物质基础,金属材料,尤其是铝合金材料,在“六五”期间得到了迅速的发展,在“七五”计划中仍然是发展的重点。在这种情况下,怎样保证和促使我国铝合金加工工业均衡,协调和稳步的发展便成为一个极其重要的课 Comrades: I would like to extend my warm congratulation on the convening of this conference and wish the conference a complete success. On the occasion of today, I will talk about the development of light alloy processing industry in China during the period of the Sixth Five-Year Plan, especially since the Seventh Technical Exchange Conference in 1983. However, As we all know, material is the material basis for the four modernizations. Metal materials, especially aluminum alloy materials, have been rapidly developed during the “6th Five-Year Plan” and are still the focus of development in the “7th Five-Year Plan”. Under such circumstances, how to ensure and promote the balanced, coordinated and steady development of China’s aluminum alloy processing industry has become an extremely important lesson
