摘要
给出了单叶双曲面新的参数方程和旋转与非旋转的单叶双曲面的腰曲线方程,进而证明了旋转单叶双曲面的腰曲线是它的腰圆,非旋转的单叶双曲面的腰曲线不是它的腰椭圓。
In this paper we have established a new parametric equation of hyperboloid of one sheet and equation of the trace of central point of a straight generator of hyperboloid of one sheet. Furthermore, we have proved the trace of central point of a straight generator of hyperboloid of one sheet of non-revo-lution is a twisted curve.
