perturbation coefficient meaning in English

扰动系数
摄动系数

In this case , we give the formulajs to calculate first - to third - - order perturbation coefficients of the eigenva1ues and eigenvectors
在这种情形下，我们给出了计算特征值和特征向量1到3阶摄动系数的计算公式。
In this case , we give the formulas to caiculate first - to third - order perturbation coefficients of the eigenvalues and first - to second - order perturbation coefficients of the eigenvectors . 1n second case where the eigenprobiem for the first - order perturbation coefficients of a defective eigenvalue hajs repeated eigenvalues , we give the formulas to calculate the first - to third - order perturbation coefficients of the eigenvalues and first order perturbation coefficients of the eigenvectors . the third case is an extension of the first case , where one of the first - order perturbation coefficients of the eigenvalues associated with the lowest - order jordan blocks is zero
第一种情形是特征值一阶摄动系数都不相同，在这种情形下，我们给出了计算特征值1到3阶摄动系数以及计算特征向量1到2阶摄动系数的计算公式；第二种情形是特征值一阶摄动系数有相等的情形，在这种情形下，我们给出了计算特征值1到3阶摄动系数以及计算特征向量1阶摄动系数的计算公式；第三种情形是第一种情形的扩展，此时对应于最低阶jordan块的特征值一阶摄动系数有一个是零。
