单叶双曲面上特殊截痕引导的参数方程

The Parameter Equation Deduced from the Hyperboloid of One Sheet of Special Section Line

从单叶双曲面上特殊截线出发,说明单叶双面的直纹性,导出单叶双曲面的另一种三角形式的参数方程.与微分几何中直纹面统一定义吻合.

From the hyperboloid of one sheet of special section line, the article analyzes its property of ruled surface and deduces the parameter equation of another trigonometric function form, which agrees with the definition of the ruled surface.
