这几年来随着经济的快速发展,我国工程机械也得到了快速的发展。但是在机械工程建造过程中却造成大量的材料消耗,这和可持续发展的战略方针背道而驰,必须要得到解决。接下来我们就来介绍一下机械工程中节约材料的途径。 In recent years with the rapid economic development, China’s construction machinery has also been rapid development. However, the huge amount of material consumed during the construction of mechanical engineering runs counter to the strategic principle of sustainable development and must be solved. Next we will introduce the ways of saving materials in mechanical engineering.
