释义 | divergence(div) The scalar product of the gradient operator ∇ with a vector. For a vector u that has components u1, u2, and u3 in the x, y, and z directions, and is a function of x, y, and z, the divergence is given by: divu = ∇.u = ∂u1/∂x + ∂u2/∂y + ∂u3/∂z . The divergence of a vector at a given point represents the flux of the vector per unit volume in the neighbourhood of that point. See also curl; Laplace equation |
