讨论了荷电(磁)质点的量子力学波方程及其解.由磁场中解的奇异性讨论了磁单极的存在;由Rubakov.Callan模型推知中子星可能含有大量磁单极.然后采用中子星的结构方程,讨论了磁荷对中子星质量半径比的约束,分别得到了磁荷对中子星质量半径比上限的影响和磁荷对中子星质量半径比下限的影响的数学表达式.
In this paper, we use the wave equation of charged mass point to prove the existence of magnetic monopole. And according to Rubakov-Callan model there could be a lot of magnetic monopoles in neutron stars. Then using the structure equation of neutron stars we obtain upper limit and lower limit of mass-radius ratio for magnetic charged neutron star.
