运用积分微元法给出空间曲线旋转任意角度所形成的旋转曲面面积的一般计算公式，其它已知的旋转曲面面积公式是它的特殊形式，从而将平面曲线的旋转曲面面积推广到了空间情形。%Using of the element method of the integral,gave the general calculation formula of the area of curve surface of rotation in arbitrary rotation angle with space curve,other known formula of the area of curve surface of rotation is its especial format.So extend the area of curve surface of rotation of the plane curve to that of the space situation.
