The explicit expressions for density functions, the mean exit time and Laplace transform of the exit time are obtained by solving the corresponding Poisson problem. The results disclose the impact on mean exit time and the Laplace transform of the exit time as $\sigma_1$ tends to $\sigma_2$.  Furthermore, an appropriate upper bound and an appropriate lower bound on the probabilities are given for switching Brownian motion. 本年度学院报告总序号： 667
