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

化学反应速率与化学达到平衡的倾向的区别 We saw that a reaction with a very large equilibrium constant has a tendency toward the products so that very little of the reactants remain equilibrium is reached. Such a reaction is said to be spontaneous. However, as we have already pointed out, spontaneous doesn't mean fast

then there exists AE R\ such that (Kuhn-Tucker condition) G(s') =0 and 1. Lagrange Method for Constrained Optimization FOC: D.L(,\)=0. The following classical theorem is from Takayama(1993, p.114). Theorem A-4 (Sufficieney). Let f and, i= ,..m, be quasi-concave, where Theorem A-1. (Lagrange). For f: and G\\, consider the following G=(.8 ) Let r' satisfy the Kuhn-Tucker condition and the FOC for (A.2). Then, x' problem is a global maximum point if max f() (1)Df(x') =0, and f is locally twice continuously differentiable,or

定义1如果两个矩阵A=[ai]和B=[b]的行数和列数分别相等,且各对应元素也相等,即a=b (i=1,2m;j=1,n),就称A和B相等,记作 A=B

An individual has a comparative advantage in the production of a particular good if she can produce it at a lower opportunity cost than other individuals. An individual has an absolute advantage in the production of a good if she can produce more of that good than another individual. using comparable amounts of time. raw materials and effort
