    "abstract": "We propose a spin-half approximation method for two-component condensation in\ndouble wells to discuss the quantum entanglement of two components. This\napproximation is presented to be valid under stationary tunneling effect for\nodd particle number of each component. The evolution of the entanglement is\nfound to be affected by the particle number both quantitatively and\nqualitatively. In detail, the maximal entanglement are shown to be hyperbolic\nlike with respect to tunneling rate and time. To successively obtain large and\nlong time sustained entanglement, the particle number should not be large.",
