摘要
基于微分几何曲线理论，将曲线弧长自然参数引入活塞环自由状态曲线方程，推导出了一种准确的活塞环自由状态曲线方程．该方程与传统的活塞环自由状态曲线计算方法相比，具有方法简便、计算精确等优点，在理论和实际上都具有重要意义．
? Based on differential geometry, a natural variable, invariant of curve, has been introduced into the developed mathematical models of the unrestrained piston ring curve and the corresponding simultaneous equations are given. Compared with the traditional calculation methods, it has been shown that the developed models can be considered to be more vigorous and easier in calculating. Numerical analyses and programming have shown the great significance both in theory and practical applications.
