摘要
导出了一类闭合曲线统一方程的表达式，圆、椭圆、三四叶玫瑰线、内外摆线都是它的特例．该方程为研究这一类曲线的共同性质提供了理论基础．
The authors derive a unitive equation of a class of closed curve, which special examples are circumference,ellipse,hypocycloid,three and four leaved rose curve.The equation offers a theoretical basis to study the generality of those curves.
