术语“特征值”的详细信息

英译术语:

eigen vector

汉语语境:

设A为n阶矩阵，若存在常数λ及n维非零向量x，使得Ax=λx，则称λ是矩阵A的特征值，x是A属于特征值λ的特征向量。通过对端盖的振动模态测试与分析，测得端盖的各阶模态参数。用有限元法建立其振动特征方程，并通过子空间迭代法求其特征值和特征向量。

英语语境:

Let A be n order matrix, if there is a nonzero constant λ and n-dimensional vector x, such that Ax = λx, λ is called the eigenvalues of matrix A, x is A feature vector which belongs toeigenvalues λ of. The modal parameters of the endcover are measured by the experimental modal analysis, and the eigenvalue and eigenvector are calculated by solving the characteristic equation with the subspace iteration method.
