Three-electron spin states and entanglement states
  In this paper, we have given the symmetrical and antisymmetrical spin and space wave functions of three-electron, and further given the full total entanglement states for the three-electron, which are related to their space and spin wave function. When we study particles entanglement we not only consider their spin entanglement and also consider their space entanglement. Otherwise, we find that electrons entanglement are restricted to the teeny range, when electrons exceed the space range, their entanglement should be broken down even disappearance, which is accordance with the experiments results.
