domestic and foreign textbooks of atomic physics，authors just write down the expressions of splittings of atomic energy
levels caused by the magnetic hyperfine interaction without and with an external magnetic field，and show some
related research examples. Here，for the cases of without and with a weak or a strong external magnetic field，the
derivation processes of these formulas and discussions about diagram drawing of these splitted energy levels are described
in details. The contents in this paper will be helpful for teachers and students in understanding and truly
mastering the related parts of knowledge in the course of“Atomic Physics”.
