ABSTRACT To attack the problems of nuclear force at the root,thus obtain a universal law of nature.That is,atomic nucleus is a nuclear ring formed by protons and neutrons alternately arrange as keys in a more even order,then the head and the tail connect,and the forming nuclear ring can self-rotate at a high-speed about self-axis,so that forming a shell structure charged liquid spherical nucleus.The forming ring tension of nuclear ring is provided by protons repel one another.So We have obtained atomic nucleus,the architecture of microscopic quantum many-body,Looking directly structure image-nuclear ring.
