Abstract
It is showed that Stability of Birkhoffian system can be determined by its conserved quantities. If a conserved quantity or a combination of some conserved quantities became a Liapunov function,then it can be used to study the stability of equilibrium and the stability of motion of the system.

Keywords:
Birkhoffian system /

conserved quantity /

Liapunov stability
