1.Then,by the Formula,we give calculation formulas of regular curves curvatures ,and discuss the general helices and flatness of curves in R~n,finally we prove a geometry inequality of curvatures and arc length.本文按照R~3经典微分几何的研究思路，对R~n中的正则曲线作了初步探讨，我们首先从R~n中正则曲线的定义入手，然后介绍了正则曲线的自然参数表示和Frenet-Serret公式，接下来利用这一重要公式给出了R~n中正则曲线的各阶曲率的计算公式，讨论了R~n中的一般螺旋线和曲线的平坦性，我们还对R~n中的闭曲线证明了一个几何不等式。

硫化平坦性分子式：CAS号：性质：胶料硫化曲线达到最高点后，在较宽的时间内保持曲线不再进一步发生变化的特性。在硫化平坦阶段橡胶交联反应已趋完成，继而发生的是交联键的重排和裂解反应，因此胶料的一系列性能曲线出现平坦区。在该阶段，硫化胶保持最佳物理性能。胶料硫化平坦性主要取决于胶料配方，尤其是促进剂和防老剂的选择，也取决于硫化温度的高低。对厚橡胶制品而言，通常要求所用胶料具有较好的硫化平坦性，以保证厚橡胶制品的均匀硫化。在配方中添加抗过硫返原剂也可以有效延长胶料的硫化平坦性。
