1. for the regular curves, we find two killing fields for the purpose of integrating the structural equations of the p-elastic curves and express the p-elastica by quadratures in a system of cylindrical coordinates . for the star-like affine curves, we solve the euler-lagrange equation by quadratures and reduced the higher order structure equation to a first order linear system by using killing field and the classification of linear lie algebra sl ( 2, r ), sl ( 3, r ) and sl ( 4, r ) . we solve the centroaffine p-elastica completely by quadratures
   对于正则曲线的情形，我们发现了两个用于求解p-弹性曲线的结构方程的killing向量场并用积分将p-弹性曲线在一个柱面坐标系中表示出来，而对仿射星形曲线的情形，我们用积分方法解出了欧拉-拉格朗日方程，利用killing向量场及线性李代数s1(2，r)、s1(3，r)和s1(4，r)的分类将高阶结构方程降为一阶线性方程，因此我们用积分完全解出了中心仿射p-弹性曲线。
2. It's difficult to find affine curve in a sentence. 用affine curve造句挺难的
