| 1. | Recently , there are some methods are utilized to study it , such as the modified lindstedt - poincare method , frequency - incremental method , stroboscopic method etc . more and more , scientists pay attention to it , as the study of solving partial differential equation is very important for the development of mechanics
目前主要的近似求解方法有改进l - p方法、频率增量法、改进的谐波平衡法、频闪法等等。由于求解偏微分方程对于力学的发展起了很重要的作用，求解偏微方程特别是非线性偏微分方程引起了很多力学工作者的注意。 |
