  We perform the complete computation of the contributions to $b\to s+\gamma,
b\to s e^{+}e^{-}, b\to s\sum \nu_{i} \bar{\nu}_{i}$ in supersymmetric model
with bilinear R-parity violation. We compare our calculations with the
evaluations in SM and the experimental results. We find that the supersymmetric
contributions can be quite large in those processes.
  From the analysis and experimental results, we can get some constraints on
the mass spectrum in the model.
