摘要

摘要: 提出平面场的梯度等于曲面切平面上Ｈ面最大斜度线对Ｈ面倾角的正切，以构作最大斜度线取代求偏导数。

Abstract: It is shown that for a curved surface,the tangent of the angle between the largest gradeline on its tangential plane and the horizontal plane is equal to the gradient of the surface.By the graphic method,the largest gradeline can be constituted in place of finding theirpartial derivatives.
