This paper discusses the method of the composition for second order linear equations . it is analogous to other second order linear equations with polynomial coefficient 摘要討論一類(lèi)二階線(xiàn)性合成方程可能的合成方式,討論方法可以用到類(lèi)似的方程上。
In this paper , we investigate the increase - order of solutions of higher order homogeneous linear differential equations with polynomial coefficients . we have obtained the precise result 摘要研究了多項(xiàng)式系數(shù)高階齊次線(xiàn)性微分方程解的增長(zhǎng)級(jí)問(wèn)題,得到了比前人更精確的結(jié)果。
In order to make it possible that unbalance of the nonlinear rotor system may be identified online , the expression of nonlinear oil film force is improved , in which the three - order polynomial coefficients may be evaluated based on the journal orbit 因此,在進(jìn)行不平衡量在線(xiàn)識(shí)別或無(wú)試重動(dòng)平衡時(shí),如果采用不變的軸承動(dòng)力系數(shù)或僅僅是隨著轉(zhuǎn)速變化的軸承動(dòng)力系數(shù),那么識(shí)別結(jié)果就會(huì)產(chǎn)生較大的誤差。
It is shown that randomized algorithms can decrease the computational complexity dramatically instead of seeking worst case guarantees . in addition , examples in this paper show that employing randomized algorithms is very efficient and has obvious advantages especially when uncertain interval parameters appear multilinearly or nonlinearly in the characteristic polynomial coefficients 研究表明,在不考慮最壞情況的意義下,隨機(jī)化算法可以顯著降低計(jì)算復(fù)雜性,另外,當(dāng)不確定區(qū)間參數(shù)以多線(xiàn)性或非線(xiàn)性的方式出現(xiàn)在特征多項(xiàng)式系數(shù)中時(shí),采用隨機(jī)化算法具有明顯的優(yōu)點(diǎn)并且是非常有效的,文中給出了計(jì)算實(shí)例。
