Abstract: Abstract: The quantum entanglement characteristic in a system composed of a multi-photon transition two-level atom interacting with an intermediate Number-Phase state is studied by means of the fully quantum theory. The influences of the atomic initial state, the parameter of field phase, the largest number of photon, the parameter of light field and the values of the transitional photon number on the entanglement degree of the system are analyzed. The results show that with the atomic initial state is entanglement state and the parameter of field phase is smaller, the entanglement degree in the system is increased obviously.; choosing appropriate values of the largest number of photon and the transition photon number, and decreasing the value of the parameter of light field, the entanglement phenomenon in the system is more obviously.
