lindstedt meaning in English
林德施泰特
Examples
- The computerized solution to lindstedt - poincare method
方法的计算机实现 - Secondly , the effectiveness and limitation of the classical perturbation , such as the method of multiple scales and the poincare - lindstedt method , are discussed in detail through a duffing oscillator with delayed velocity feedback . it is shown that the two perturbation methods are effective only in solving the approximate solution of the first two orders . an ambiguity or paradox will be encountered when they are used to seeking for the third or higher order approximation of solution
其次，以一具有时滞速度反馈的duffing系统为例，研究了经典摄动法如多尺度法， poincar - lindstedt法等在求解时滞微分方程级数解时的适用性和局限性问题，指出利用这些方法只能有效求得系统的前两阶近似解，而在求系统的三次以上近似解时会出现矛盾或二义性。 - 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。
