节约用铜已在我们全国范围内行动起来了。各个设计、建设单位以及制造厂在执行中共中央和国务院节省有色金属的指示中,曾做了很多工作,多方面研究如何切省用铜,以及采用铜的代用品。最近人民日报所发表的沈阳,上海,天津等地在制造上节药用铜的巨大成绩清楚地说明了这一点。但是我们在设计中对节约用铜的指示还是执行得不够的。当然,旧有的避免在设计中采用铝的规定是一个客观原因。 Saving copper has already taken action in our country. Various design, construction units, and manufacturing factories have done a lot of work in the implementation of the directives of the Central Committee of the Communist Party of China and the State Council to save non-ferrous metals. They have studied in many ways how to cut copper and substitute copper. The great achievements in the manufacture of copper for medicinal use in Shenyang, Shanghai, and Tianjin recently published by the People’s Daily clearly illustrate this point. However, we have not implemented enough instructions for saving copper in our design. Of course, the old rule to avoid the use of aluminum in design is an objective reason.
