从本世纪40年代起，随着美国原子弹爆炸的成功，一场新的科技革命──核技术革命开始了，核能从科学理论的研究阶段进入了实际应用阶段。核能的应用极大地推进了科技进步和生产力的发展。但是，事物总是一分为二的，原子弹所展示的巨大威力，又成为少数几个掌握核技术国家进行 Since the 1940s of this century, with the success of the atomic bombing in the United States, a new revolution in science and technology - nuclear technology revolution has begun and nuclear energy has been put into practical use from the research phase of scientific theory. The application of nuclear energy has greatly advanced the progress of science and technology and the development of productivity. However, things are always divided into two parts. The great power demonstrated by the atomic bomb has also become one of the few countries that have mastered nuclear technology.
