原子和原子核物理学是研究原子和原子核内部结构和运动规律的科学 ,对于认识物质微观结构 ,揭示物质世界的本质 ,进一步学习现代化科学技术 ,进行辩证唯物主义教育、发展科学思维能力有其重要作用 .不仅如此 ,原子物理部分是其它各部分知识的扩展和升华 ,它与力学、电学、热学 Atomic and nuclear physics is the science that studies the internal structure and movement laws of atoms and atomic nuclei. It plays an important role in understanding the microstructure of matter, revealing the essence of the material world, learning modern science and technology, conducting dialectical materialism education, and developing scientific thinking ability. Not only that, the atomic physics part is the expansion and sublimation of other parts of knowledge, it is related to mechanics, electricity, and thermals.
