The computerized solution to lindstedt - poincare method
方法的計算機實現 -
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，以一具有時滯速度反饋的duffing系統為例，研究了經典攝動法如多尺度法， poincar - lindstedt法等在求解時滯微分方程級數解時的適用性和局限性問題，指出利用這些方法只能有效求得系統的前兩階近似解，而在求系統的三次以上近似解時會出現矛盾或二義性。 -
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進l - p方法、頻率增量法、改進的諧波平衡法、頻閃法等等。由於求解偏微分方程對于力學的發展起了很重要的作用，求解偏微方程特別是非線性偏微分方程引起了很多力學工作者的注意。
