Abstract：
In this paper we have introdnoed the concept of U interyals for denumerable Mar-
kov processes, then analysed the flying-points and U intervals for a process. We have
found relations between U intervals and Kolmogoroff's backward and forward equati-
ons. Using the concept of U intervals for ： a process, we can investigate the exit and
entrance problems for a process more clearly and effectively.
