Abstract:
The Hamiltonian operator ∇ and the common expressions such as the Laplacian operator, gradient, divergence, and curl generated by it are not the same in different curve coordinate systems. This paper defines a three-dimensional orthogonal curve coordinate system(u1, u2, u3), introducing coordinate factor h1, h2, h3, deriving the general form of ∇, ∇∅, ∇-A, ∇ΧA, ∇2, and the general expression of Poisson equation as well as Laplace equation.
