20世纪核科学技术取得了突飞猛进的发展,并为人类社会的进步和文明做出了重大的贡献。天然放射性和核裂变的发现,使世界进入了原子能时代,并开始有了核工业。原子核的裂变和聚变可以释放出大量的能量,可以用来发电,也可以用来制造原子弹和氢弹。原子核的裂变和衰变及各种核反应可以产生各种粒子和射线,并用来研究各种物质的特性和应用于能源、工业、农业、医学和环保等领域。当今,核技术在国际上许多方面已经形成了巨大的产业。根
The 20th century nuclear science and technology have made rapid progress, and made great contributions to the progress and civilization of human society. The discovery of natural radioactivity and nuclear fission brought the world into the atomic energy era and began to have nuclear industry. Nuclear fission and fusion can release large amounts of energy, can be used to generate electricity, can also be used to make atomic bombs and hydrogen bombs. Nuclear fission and decay and various nuclear reactions can produce a variety of particles and rays, and used to study the characteristics of various substances and applications in the fields of energy, industry, agriculture, medicine and environmental protection. Today, nuclear technology has formed a huge industry in many aspects in the world. root
