摘要：
We present a way to construct and solve the small-polaron model with general open boundary conditions. The Bethe ansatz equations and the energy spectrum are obtained. It is found that the Grassmann numbers play a crucial role in the construction of the Hamiltonian as well as the reflection equations for the model. The way presented is applicable for some other fermion models, (C) 1999 Elsevier Science B.V.
