basis vector造句
例句與造句
- Coordinate basis vector
坐標(biāo)基向量 - Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it , we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity . then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually
將系統(tǒng)的哈密頓量在一個(gè)適當(dāng)?shù)恼换赶抡归_(kāi)并對(duì)角化，得到系統(tǒng)的能譜，分別計(jì)算系統(tǒng)能譜的能級(jí)間距分布函數(shù)和譜剛度，研究了該系統(tǒng)量子能譜的統(tǒng)計(jì)特征隨磁感應(yīng)強(qiáng)度大小的改變而表現(xiàn)出的系統(tǒng)運(yùn)動(dòng)由規(guī)則到混沌的漸進(jìn)變化。 - ( 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
