摘要
The analogy between the theory of 2-level atoms and the relevant classical theory is ex-amined in detail. This familiar analogy shown in the Heisenberg picture will be damaged,when we calculate the values of physical quantities in specific states. This damage has rela-tion with the definition of state. If we use a pair of vectors to define the state of a system,that analogy can be kept without damage.
