 high order differential equation
 高阶微分方程
 Solving high order differential equation, with main oscillation including first order base band, by equivalent small parameter method, could be simple and convenient. Approximate solution is exacter than that by perturbation method, KBM method, the multiple scale method, harmonic balance method, etc. 应用等效小参量法时,主振荡仅包含基波的高阶微分方程解法的特点是求解过程相当简单,近似解的准确度高于传统的扰动法、KBM法、多尺度法、谐波平衡法等。 短句来源
