  The minimum supersymmetric standard model with bilinear R-parity violation is
studied systematically. Considering low-energy supersymmetry, we examine the
structure of the bilinear R-parity violating model carefully. We analyze the
mixing such as Higgs bosons with sleptons, neutralinos with neutrinos and
charginos with charged leptons in the model. Possible and some important
physics results such as the lightest Higgs may heavy than the weak Z-boson at
tree level etc are obtained. The Feynman rules for the model are derived in
$'$t Hooft- Feynman gauge, which is convenient if perturbative calculations are
needed beyond the tree level.
