1. (3 ) the re-orthonormalization technique is used to solve the loss of orthonormality of basis vector during the classical gmres method solving large-scale three dimensional elasto-static be problems . based on the characteristic of fundamental solution and the coefficient matrix, several precondition methods are studied . by using the technique of re-orthonoramalization and precondition, the practical gmres method is developed based on the classical one
   (3)采用重正交技術(shù)解決了經(jīng)典gmres方法在求解大型三維彈性靜力邊界元問題過程中出現(xiàn)的基向量正交性喪失的問題；結(jié)合邊界元基本解和系數(shù)矩陣的特點以及并行化的要求，研究了幾種預(yù)條件技術(shù)；并以重正交技術(shù)和預(yù)條件技術(shù)實現(xiàn)了經(jīng)典gmres的實用化。
2. in order to improve the efficiency of the mesh generation, we employ the transfinite interpolation method . in low speed flow ( m < 0.05 ), the low mach will aggravate the difference between eigenvalues of the system and make the convergence sharply difficult . as for this, we use the preconditioning method to remove it
   另外，我們求解的是極低馬赫數(shù)下的流場(m0.05)，極低的馬赫數(shù)會導(dǎo)致可壓流動方程十分僵硬而難以收斂，對此，我們對n-s方程進行了矩陣預(yù)處理。
3. It's difficult to find precondition method in a sentence. 用precondition method造句挺難的
