泰勒近似
英文
taylors approximation-
Following is our main work and important conclusions : ( 1 ) the question of energy spectrum hardening. we used the klein - nishina ' s differential scatter formula, meanwhile utilize the thaler progression to spread out, and neglected the high - power, and then we deduced a theoretical formula of correction of energy spectrum hardening
其主要工作和結論如下: ( 1 )對x射線能譜硬化問題,把klein - nishina微分散射方程,利用泰勒級數展開,在忽略高次項的情形下,近似地推導出了能譜硬化修正公式。Kalman filter is an optimal filter algorithm in the minimum - mean - square - error sense, meanwhile extended kalman filter is a sub - optimal filter algorithm, which derived from the linearization of nonlinear system using taylor expansion. while the non - linearity of the system is not extreme strong, ekf can achieve approximately optimal filter effect
Kf是最小均方意義下的最優濾波演算法, ekf則是利用一階泰勒展開將非線性系統線性化而得到的一種次優濾波演算法,在非線性不是特別嚴重的情況下, ekf有著近似最優的濾波效果。The application of taloy series in approximation calculation
泰勒級數在近似計算中的應用This is analogous to the successive approximation given by the terms of a taylor expansion.
這類似通過泰勒法展開各項所給出的逐次逼近法。Firstly part of quadratic term of taylor series is chosen ; a low - dimension surface is used to approximate limit state surface ; and the modified reliability formula is derived
首次選取泰勒級數的部分二次項,用一個距原點最近點處擬合的超低維曲面近似極限狀態面。Based on the analysis of previous work in detail, a scheme of a - posteriori error estimation is introduced into the local boundary integral equation method ( lbiem ), which is constructed with the difference between the raw solutions of lbiem and the post - processing solutions with taylor expansion and moving least square approximation ( mlsa )
