摘要
针对曲面线型图的缺陷，本文提出变线位置、变化率线等新概念，论证复杂曲面的变化规律，给出一种更准确、更科学表达曲面空间形状的新方法。为解决复杂曲面造型及图形处理程序化提供切实可行的方案。
It is posed in the original draft the new concepts of the change lines it′s position and the lines of change rate which is aimed at the defect of curved surface drawing or lines, the changeable regular pattern of the complex curved surface is proved in the draft and a new method is given in it which is more exact and scientific to express the space form of curved surface and a feasible scheme is also provided to solve the model of complex curved surface and procedure of graph treatment.
