This paper tries to provide a new method of the plow bottom surface design by a mathematical method.
本文试图为犁体曲面的设计提供一种新的设计方法——用数学的方法设计犁体曲面。
In the design of plow bottom surface formed by horizontal straight-line elements, it is important to determine the shape and parameters of guiding curve.
在设计水平直元线犁体曲面时，确定其导曲线的形状和参数是重要的一环。
Based on this foundation, basic models of plow-bottom surface are ruled surface and negative constant curvature surface.
据此得出直纹和负常曲率两类曲面可作为犁体曲面的基本模型。
