摘要
通过对振荡曲线进行分析、筛选分段边界点、计算最佳拟合多项式的系数和阶数,完成对振荡曲线的拟合和曲线边界修正处理,从而得到力、位移、能量的特征值。
Through analyzing the oscillating curves,selecting the boundary points of piecewise curve,and counting the prime coefficient and rank of the best fitting polynomial,the oscillating curve is fitted,and the boundary of the fitting curve is amended. Then,the eigenvalues of force,displacement and energy are achieved.
