Abstract: \[\left\{ \begin{aligned}

  & \mathbf{\dot{p}}=\frac{\partial H}{\partial \mathbf{q}} \\ 

 & \mathbf{\dot{q}}=-\frac{\partial H}{\partial \mathbf{p}} \\ 

\end{aligned} \right.\]

   is containing a full-time solution so there are  the limits of $\frac 1t\int_0^t {\mathbf p}(s)ds$  and $\frac 1t\int_0^t {\mathbf q}(s)ds$ as $t\to\infty$ for any bounded solution $(\mathbf {p,q})$ of  the Hamilton system.
