On the dynamic flows
  It is investigated a possibility of physical interpretation of vector fields (dynamic flows) in Euclidean spaces of higher dimension. There are analyzed the methods of measurements of dynamic flows, the characteristics of dynamic flow and the connection between its differential and integral characteristics. It is obtained the criterion of local minimality of (n-1)-surfaces that is not connected with interior geometry of surface. It is analyzed some analogy between harmonicity of dynamic flows and dynamic principle of nature.
