摘要：建立4种曲面面积的求解方法,为实际应用提供了选择性.第1种方法是根据平面面积等于其正投影面积除以该平面与投影面夹角的余弦,将此原理转移到曲面面积的求解;第2种方法是用传统数学方法求曲面面积;第3种方法是应用展开方法求曲面面积;第4种方法是用计算机表示的方法求曲面面积,这种方法将形、数、计算机相结合,适合于各种曲面面积的求解.
Four applications is divided by the kinds of curved surface area method are established, and the selection provided. The first method is based on the principle that planar area is equ cosine of the angle between the plane and the projection surface, thi for practical al to the area s principle is transferred to the surface area of the solution. The second one is to use the traditional mathematical method for surface area. The third one is to apply expansion method for surface area. The fourth one which is synthesized with graph, math and computer technology, is presented , suitable for all kinds of surface area of the model.
