  We analyze the ground state structure of the supersymmetric sine-Gordon model
via the lattice regularization. The nonlinear integral equations are derived
for any values of the boundary parameters by the analytic continuation and
showed three different forms depending on the boundary parameters. We discuss
the state that each set of the nonlinear integral equations characterizes in
the absence of source terms. Four different pictures of the ground state are
found by numerically studying the positions of zeros in the auxiliary
functions. We suggest the existence of two classes in the SUSY sine-Gordon
model, which cannot be mixed each other.
