核素分类是物质世界核素层次基本性质规律的统一。在自然科学中的意义类似于元素周期律 ,具有重要科学价值。近年来 ,核素分类研究在山西省自然科学基金与科技部攀登计划预选项目资助下 ,1997年出版了科学版《正方形核素图》 ,正式向国内外科学界宣布了核素比幻数更基本的规律 Radionuclide classification is the unity of the basic nature of the radionuclides in the material world. The meaning in the natural science is similar to the periodic law of the element, which has important scientific value. In recent years, the research on radionuclide classification was funded by the Natural Science Foundation of Shanxi Province and the Ministry of Science and Technology’s Climbing Plan Pre-selection Project. In 1997, the scientific version of the “square radionuclide map” was published and formally announced to scientists at home and abroad that radionuclides are more fundamental than their magic numbers The law
