The simplified solution to one kind of nonlinear differential equation set , and the expression to special solution are given 摘要給出一類非齊線性微分方程組特解和簡捷求法,并提供了特解的表達式。
It is proved that when frequency is low , there can be significant discrepancies between them , with frequency increasing , the simplified solutions converge to the new more rigorous one 研究表明它們與本文嚴格解的差別主要限于低頻段,隨激振頻率的提高,不同解將趨于一致。
