In this paper, we mainly discuss the "penalty function" of the risk processes of a Markovian risk model.Using the Integro - differential equation we established, we get the Integro - differential equation for the ruin probability, the distribution of the deficit at ruin, and the joint cumulative distribution of the deficit at ruin and the surplus before ruin respectively.
