“稀有金属最可贵,战略前途更辉煌”,这是陈毅同志生前视察西南大三线建设时写下的光辉诗句,它凝聚着老一辈无产阶级革命家对我国稀有金属材料工业的深切关怀和殷切期望。 “Rare metals are the most valuable and the future of the strategy is even more brilliant.” This is a glorious poem written by Comrade Chen Yi during his inspection visit to the construction of the southwestern major three lines. It embodies the deep concern and ardent expectations of the older proletarian revolutionaries in China’s rare metal materials industry .
