Properties of the Unified Coordinates
We shall call the system of coordinates (λ, ξ, η, ς) defined in (6.1) unified in the sense that it unifies the Eulerian system when Q = 0 with the Lagrangian when Q = q, and also in the sense that the system of governing equations (6.19) unites the geometrical conservation laws with the physical ones to form a closed system of PDE in conservation form.
