Under the hypothesis of model,some probable characteristics such as transition probability,stationary distribution,staying time distribution were discussed(To date,we have not seen the application of the model in shooting effectiveness being discussed in Any public references).

ln statistical equilibrium,the author obtains the equilibrium distribution of queue length and that of waiting queue length,the average of queue length and that of waiting queue length as well as the equilibrium distribution of waiting time and that of staying time, the average of waiting time and that of staying time.
