摘要
通过对控制平面、二次曲面及投影面三者之间相对位置的参数进行投影分析和对平面与二次曲面的交线投影成圆周条件的证明 ,为方便准确地求解二次曲面的截交线 ,提供了理论根据 ,为其程序编制及计算机绘图提供了新的行之有效的方法。
A theoretical foundation is turned out,through the analysis for the projection of parameters of relative positions of a cutting plane,a quadratic surface and its projection planes and the demonstration of the conditions for projected linecircle ofacutting plane and a quadratic surface,to reslove precisely the section line of a quadratic surface,And it also provides a new method for computer programming and drawing.
