The optical potential of a nucleon in the nuclear medium is identified with the nucleon self-energy.

核子的光学势等价于核子在核介质中的自能，论文中RMOP的实部用G=V+AG在DBHF方法下计算得到，虚部则采用二级G矩阵极化图的虚部。

If we want to get the effective mass by the method of computing the meson self-energy , we need to consider the change of the effective mass of the nucleon along with the increasing density of the nuclear matter,namely considering the fluctuation of the vaccum.

很多研究[3，4，5，6，11，12]表明了上式描述的规律是正确的，如果用计算介子自能的方法来得到介子的有效质量，需要考虑核子的有效质量的随核物质的密度的变化，即需要考虑核子的真空涨落，当不考虑核子有效质量随核物质密度变化的时候，ρ介子、ω介子的有效质量一般是上升的。

Nuclear Physics 1930, the Star of energy will be satisfied with the solution to the rapid development of the internal structure of stars; Hours map and based on the experimental results, the establishment of a stellar evolution of scientific theory. Einstein's general theory of relativity, in 1917 by the structure of the universe, the establishment of a relativistic cosmology. In 1929 the Hubble Space Telescope found redshifts and distances of the future, relations between the people of the gravitational theory of general relativity River from the data objects, size and structure of the material movement and the formation of modern cosmology.

三十年代原子核物理学的发展﹐使恒星能源的疑问获得满意的解决﹐从而使恒星内部结构理论迅速发展﹔并且依据赫罗图的实测结果﹐确立了恒星演化的科学理论。1917年爱因斯坦用广义相对论分析宇宙的结构﹐创立了相对论宇宙学。1929年哈勃发现了河外星系的谱线红移与距离间的关系﹐以后人们利用广义相对论的引力理论来分析有关河外天体的观测资料﹐探索大尺度上的物质结构和运动﹐这就形成了现代宇宙学。
