By means of error analysis of recursion process of precise integration , it is found that the essential reason of obtaining the high precise numerical results of exponential matrix in the precise integration method is that the relative error of numerical computation is not enlarged in a whole recurrent process
通過(guò)對(duì)精細(xì)積分法遞推過(guò)程的誤差分析，發(fā)現(xiàn)該方法能獲得高精度數(shù)值結(jié)果的根本原因是：數(shù)值計(jì)算的相對(duì)誤差不隨遞推過(guò)程的進(jìn)行而擴(kuò)散。
This paper suggests that the integral of the state equation is evaluated directly through the exponential matrix based on the pim , thus several series solutions are obtained . utilizing the symmetry of matrices and the idea of substructure , the computational precision and efficiency of the pim are improved
本文深入研究精細(xì)積分及動(dòng)力方程算法，基于指數(shù)矩陣計(jì)算、 pade逼近理論，在時(shí)域上對(duì)非線性動(dòng)力狀態(tài)方程直接積分求解，構(gòu)建若干系統(tǒng)響應(yīng)求解格式，并分析了算法精度、效率；通過(guò)矩陣變換，利用矩陣對(duì)稱(chēng)性、子結(jié)構(gòu)等方法改進(jìn)精細(xì)積分計(jì)算效率。
