What is Convective Heat Transfer? You have already experienced it. Difficulty lies in generalizing our experience; filtering it down to a few laws: learning how to apply these laws to systems we engineers design and use Here is what i want you to do:

工程实践中有多种振动问题,如桥梁或建筑物的振 动,机械机件、飞机机翼的振动,及一些稳定性分析和 相关分析可转化为求矩阵特征值与特征向量的问题 1已知A=(an)mn,求代数方程q(1)=det(I-A)=0 的根。φ(λ)称为舶特征多项式,一般有n个零点,称 为的特征值 2设为伯的特征值,求相应的齐次方程(4/-A)x=0 的非零解(即求Ax=λx的非零解),x称为矩阵A对应 于孔的特征向量

显然,a不是厄米算符,a≠a。但ata是厄米算符,(ata)=a'a。 问题:aa是什么力学量? [a=0,∴与i共同本征态,只要求解了首的本征方程,就求解了 的本征方程

1.设A是n阶矩阵,且经过 Gauss消去法一步消去后变为an (0A2 证明: (1)如果A是实对称矩阵,那么A2也是对称的; (2)如果ala(i=1,2,L,n),称A为(按行)严格对角占优矩阵,那么A2也是严格对角 占优
