摘要：
A fermion model consisting of two chains with interchain tunneling is formulated and solved exactly by the Bethe-ansatz method. The interchain tunneling leads to Cooper-pair-like bound states and a threshold energy is required to overcome the binding energy. The correlation functions manifest superconducting properties.
