摘要
本文讨论四阶椭园方程一类周期问题的差分方法及在过渡面、自由曲面设计中的应用。同时通过实例讨论调整定解问题中的多数以修改曲面形状的方法。
The paper discusses the difference method of solving the 4th ordered elliptic partial dif-ferential equations and its application to the design of blending and free form surfaces. Also,studied is,via some samples,the modification of surface shapes by varying the boundary con-ditions,Results show that the method is feasible in free form surface design.
