| 单词 | curl |
| 释义 | curl(rot) The vector 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 (with respective unit vectors i, j, and k), and is a function of x, y, and z, the curl is given by: curlu = ∇ × u = (∂u3/∂y - ∂u2/∂z(i + (∂u1/∂z - ∂u3/∂x)j + (∂u2/∂x - ∂u1/∂y)k.
