1 Definition Subordination means putting a grammatical unit in a lower rank or position. A grammatical unit that functions as a constituent of another unit of equal or lower rank of structure is called subordinate constructi, which might

1.某温度时,NH4C(s)分解压力是标准压力,则分解反应的平衡常数K为: C(A)1(B)1/2(C)1/4(D)1/8

一、齐次线性方程组 例1设A为n阶矩阵,证明 R(A)=R(). 证明由于若Ax=0,有AAx=0,这说明凡是 Ax=0的解必为AAx=0的解。 另一方面,若AAx=0,我们记Ax=y,则有 yy=x'a'ax=x(a'Ax)=0,则y=0,亦 即Ax=0.这说明凡是AAx=0的解必为Ax=0的 解。故A'Ax=0与Ax=0的同解。当两齐次线性 方程组同解,意味着它们的基础解系包含的向 量个数相等,亦即有: n-R(A)=n-R(A'A) 所以R(A)=R(A'a)

1.(01-1-03)设矩阵A满足A2+A-4E=O,其中E为单位矩阵,则(A-E)-1= 解应填(A+2E) 应设法分解出A-E因子.由A2+A-4E=O,有 (-)(a+2e)=2e,即(a-e)-(a+2e)=e
