The Curl

旋度
The curl of a vector function is the vector product of the del operator with a vector function:
where i,j,k are unit vectors in the x, y, z directions. It can also be expressed in determinant form:

Curl in cylindrical and sphericalcoordinate systems

柱坐标和球坐标中的旋度
矢量函数的旋度是del算符与矢量函数的向量积:其中i,j,k是x,y,z方向的单位矢量。它也可以用行列式形式表示:
