技术革新、技术革命是实现四个现代化的必要手段。没有现代化的科学技术就不可能有现代化的工业、农业和国防。所、以要实现“四化”首先应改革现有技术。如果“草木依旧”,何来“万象更新”?我们只有通过一项一项的改革,才能给祖国带来“四化”的春天。就冶金工业来讲,开展双革具有非常重要的意义。我国冶金工业是在陈旧设备和工艺的基础上建立起来的,除近期建设 Technological innovation and technological revolution are the necessary means to realize the four modernizations. Without modern science and technology, there can be no modern industry, agriculture and national defense.
